I am enjoying discovering the gutter creatures who share my home. Gathering video footage of an alternative cosmos to go towards making work which will be shown in Occupied: Strange Company at the Safehouse next year, a group exhibition curated by Julie Hoyle.

My experiments growing citric acid crystals have been going well. I am filming these transformations under polarised light which reveals the many vibrant colours but I also like the images without the filter. The structures remind me of feathers so I am thinking about creatures that flutter as well as those that swim.

Time in the studio has been spent checking over and preparing works that will be showing in Cosmos: The Art of Observing Space curated by Ione Parkin which opens in the new year. I am thrilled to be part of this exhibition bringing together contemporary and historic artists and featuring an extraordinary range of work inspired by the cosmos. I have completed a test build of The Azimuth Obelisk (of sedimentary knowledge) using a new internal structure for before packing it all away again ready for transport to The Royal West of England Academy in Bristol. This work is a reimagining of an permanent azimuth mark erected at Hartland Magnetic Observatory in North Devon from which the drift of the magnetic north pole is monitored. Made of many layers hand torn from recycled works on paper it echoes the geological and magnetic history of the Earth which is secreted in the strata of sedimentary rock. The protruding tabs of paper seen in these studio images are markers for each section of paper squares of a tapering size and will get tucked away at installation in the gallery. With the added thickness of my new studio roof insulation the obelisk only just fits in now.

I have started work on inserting copper segments into the new sculpture for the Instruments of the Anemoi series. The other larger pieces of etched and patinated copper were added at the time of casting, held in place with tape and hope when the concrete was poured into the mould. This series of sculptures are suggestive of the pedestals that support various instruments used in monitoring the Earths’ magnetic field but are envisaged here as speculative objects used by the wind gods as the first emissaries of navigation.

I am still battling with writing text for The Book of Reversals, an artist book that responds to the record of Earth’s magnetic field reversals being written in bands of minerals on the ocean floor.

The Earth’s magnetic field has been a fascinating mystery for many hundreds of years and Gillian Turner’s book North Pole, South Pole recounts the stories of those who sought to solve its origin and mechanism. Something I hope to look at in more depth is how pottery and bricks preserve the direction of the magnetic field in their minerals during the process of firing which heats and then cools the clay – the same process that occurs in a lava flow. Iron-bearing minerals (like magnetite) in clay become “magnetic” when heated in a kiln. As the pottery cools, these minerals lock into the Earth’s magnetic field direction and strength at that time. The study of the magnetic properties of ancient pottery, known as archaeomagnetism, has been used to make records of the inclination of the magnetic field from past millennia. Inspired by these studies of manmade artefacts to determine the historical position of the north magnetic pole, physicists Bernard Brunhes and Pierre David took samples from exposed lava flows and their underlying clay in central France. In 1906 they came to the astonishing conclusion that about six million years ago the magnetic field seemed to point in the opposite direction, the first indication of magnetic field reversals.

Also with thanks to Gillian Turner’s book North Pole, South Pole I have learnt that there were early hydrogen balloon ascents to determine if the Earth’s magnetic field intensity varied with altitude, helping to decide if the magnetic field came from within the Earth or was extra terrestrial. In 1804 Jean-Baptiste Biot and Joseph Louis Gay-Lussac made a pioneering ascent to 4,000 feet (1.2km). In Turner’s book she writes that the dip needle necessary to take the measurements iced up and so the results were unreliable. I feel for them, but it seems they conducted many other experiments on temperature and gases in the atmosphere while aloft and in any case we now know they would have needed to ascend many kilometres higher than they achieved to notice any weakening in the magnetic field.

This plate is from John Howard Appleton’s (1844-1930) Chemistry, Developed by Facts and Principles Drawn Chiefly from the Non-Metals, published in 1884.

I am trying to remember when I first had the idea to launch a cloud chamber in the payload of a high altitude balloon. I knew about the hot-air balloon experiments carried by Victor Hess to determine the origin of cosmic radiation, and his discovery in 1912, when he made an ascent to over 5km during a near-total eclipse of the Sun, that radiation had to be coming from further out in space.

Hess on his return from the 1912 balloon ascent – Alan Watson pointed out that this was obviously staged at another time as he would not have been standing looking so well after his ordeal.

I remember looking into the dark skies during a residency at Allenheads Contemporary Arts and wondering about all the activity that I couldn’t see. I decided then I would like to film at 15km where most subatomic cosmic ray activity takes place, even if nothing would show on the film.

A high altitude balloon flight seemed the perfect solution and I was very grateful for the help I subsequently received from Imperial College Space Society and The UK High Altitude Society. The decision to include a cloud chamber in the payload was always a risk and as it turned out nothing of the cosmic ray activity was captured on film. However, the balloon did reach an altitude of over 37km and the payload was successfully recovered with some amazing video footage of its journey.

The record height for a hot air balloon ascent is 21km so in theory it could be possible to send a cloud chamber up in a hot-air balloon and film at altitude with potential for more success if some brave person were on board to operate the camera. Unlikely to be me.

Some intriguing news of ORC’s on the RAS websiteThe most distant and most powerful ‘odd radio circle’ (ORC) known so far has been discovered by astronomers. These curious rings are a relatively new astronomical phenomenon, having been detected for the first time just six years ago. Only a handful of confirmed examples are known – most of which are 10-20 times the size of our Milky Way galaxy. ORCs are enormous, faint, ring-shaped structures of radio emission surrounding galaxies which are visible only in the radio band of the electromagnetic spectrum and consist of relativistic, magnetised plasma. the three new cosmic rings – discovered not by automated software but by sharp-eyed citizen scientists – represent an important step toward unlocking the secrets of these vast, puzzling structures.

Out and About

A wonderful evening with artist in residence Melanie King at Passengers connecting the celestial with the architecture of the grade II listed Brunswick Centre in Bloomsbury, London. Melanie used the residency opportunity to explore the duotone cyanotype process using multiple layers of cyanotype to mimic astronomical imaging construction and even used cyanotypes to create an of the Moon. The beautiful results were presented at an evening event with the additional treat of live telescope viewing of the Moon and Saturn from the second floor terrace of the Brunswick centre under the engaging guidance of astronomer and science communicator Paul Hill.

Liz Elton’s sensitive work Black and Blue (compostable bio materials, cabbage and fruit dye saddened with iron, silk, poppy and sage seeds) showing in A Changed Environment at Messums London. This group show examines changing ideas of beauty, ecology, and sustainability, as well as themes of place, memory, and identity, revealing how connections to the natural world can inspire both understanding and hope. I love the delicacy of this new work and the term ‘saddened by iron’ which is used in the dying process to dull a colour, and which, as Liz says, also emotes the hardships of industrial life.

Cosmic Dust talk by expert on extraterrestrial space dust, and how it can impact astronomy and wider human endeavours in space, Penny Wozniakiewicz at The Royal Astronomical Society. ‘Natural’ cosmic dust is being polluted by man made dust from space debris. This is a real problem created by dead satellites, old upper stages of rockets, fragments form exploded rocket or stages, flecks of paint, aluminium oxide spheres from solid rocket burns, dropped space equipment. When any of this debris collides a cloud of smaller debris is ejected, this process is self propagating and even the tiniest piece of debris can cause serious damage to spacecraft and satellites. This is called the Kessler syndrome, a cascading effect that could render orbital space unusable for generations, threatening satellites, the International Space Station, and future space travel.

Good to visit the The London Group show 2025 at Copeland Gallery where lots of friends are showing excellent work and also to discover new work and artists.

I found Majid Majid’s video Faith Amongst The Ruins a difficult but compelling work. So scary and horrific because we know this is real footage, some of which I had seen before at the time of the attacks on hotels housing asylum seekers and refugees, but it is still so disturbing to watch these people, with so many children present, cheer on the violence. They have no empathy with the terrified people trapped inside the hotel or for the person in the car who is ambushed and stabbed. The glee of those filming the assault is chilling.

He writes: “As a refugee, I know places shaped by fear and rejection. This work revisits UK sites of last summer’s Islamophobic and racist violence, a mosque, a street, and a hotel housing asylum seekers transforming them through prayer. Placing a mat where hostility flared, I reclaim space as sacred ground. Video and traces of violence form a counter-narrative of dignity, belonging, and resilience.”

Three beautifully directed films screened at FormaHQ as part of The Open Road series of artists moving image works, co-commissioned by a partnership of visual arts organisations. The works are loosely inspired by The Canterbury Tales, drawing from a disparate cast of characters to recount competing stories in a patchwork of styles. David Blandy (Commons), Amaal Said (Open Country) and Sam Williams (The Eel’s Tale) each draw on storytelling traditions to give fresh perspectives on their journeys, on foot, by sea and through time. Heartbreaking to hear how terrified Amaal Said was to leave London for the open country of the south coast, especially with the current rise in overt racism, when out looking for locations and that they did suffer racist abuse while filming. Hers is a gentle and warm study of a mother and daughter and an absent grandmother, a longing for home and to feel ‘at home’. Sam William’s film sets the plight of the highly endangered glass eels who journey 4,000 miles from the Sargasso Sea to the Medway wetlands in Kent, swept along by currents, undergoing bodily transformation, following an instinctive desire on this epic migration alongside two other watery tales of transformative journeys across boundaries of identity and freedom. Coincidently, a recent episode of the Infinite Monkey Cage is all about these mysterious eels. David Blandy turned his attention to the vast and disparate collection of artefacts held in the Tunbridge Wells museum and gave some of these specimens a voice to tell of how they had lived before they became a part of this collective of human taxonomy.

Cristina Iglesias The Shore at Hauser & Wirth features large-scale bronze works from the artist’s Littoral (Lunar Meteorite) series, part of her ongoing exploration of geological themes. The word ‘littoral’ refers to something relating to or situated along a coast or shore, or the region where the land meets the water. The weightiness of the objects is impressive ( I can’t imagine how they were brought into the gallery even with the technology available today – after coming here from the talk on stone henge and the incredible feat of bringing the standing stones across rough terrain for many kilometres and up a slope 5000 years ago seems even more impossible – yet there they are). The sound of water bubbling within each piece draws you to peer within and stay with the piece perhaps longer. The audience is invited to touch the sculptures. The bronze is polished and does need to be used and worn away in a more effective organic and dirty process. They are very clean.

The Royal Astronomical Society lecture Sighting the Sun and Moon? at Stonehenge – by Archaeoastronomist Prof. Clive Ruggles. Debunking many myths and overspeculation, concerning the use of the monument for observations of the sky the professor was clear about what can sensibly be said about the relationship of Stonehenge to the Sun, considering the conventional archaeological evidence that has been uncovered in recent years. He also recommended visiting the day before or after the actual solstice if possible for an experience without the many crowds as the alignment is almost identical. Also visiting at sunset can be just as magical and quieter. He turned his attention to the Moon, questioning if our prehistoric forebears also celebrated the occurrence of a major lunar standstill, an event occurring every 18.6 years around which time the Moon can be seen at fortnightly intervals exceptionally far to the north and south.

Karl Singporewala’s sculptural interpretations of Zoroastrian symbolism in Cosmos, Memory, Scale at SOAS Gallery convey a meditation on how material and memory intersect to shape the human experience. Cosmos speaks to both his fascination with astrophysics together with a metaphysical belief in the alignments of life. Stars and geometric forms recur as motifs, refracting both spiritual navigation and mathematical structure. Memory is treated as a living, shifting phenomenon. Inspired by oral tradition, family stories and inherited rituals. Scale, is used both literally and metaphorically in shifting perspectives and unexpected relationships. Good Thoughts, Good Words, Good Deeds.

I spent a happy morning at the Geologists Association Festival of Geology 2025. This included a fascinating lecture The Early Evolution of Animal Life by palaeobiologist Frankie Dunn focused on the origin and early evolution of animals and particularly on the fossil record of the late Ediacaran Period (approximately 570 – 540 million years ago) – just before the Cambrian explosion of life. The aim of her research is to understand how animal body plans evolved in deep time. There also was some amazing and unique pudding stone on display.

I also picked up a great little book full of wonderful geologically enriching words by Marcia Bjornerud.

The Geological Unconscious had a wonderful six week run at Hypha HQ, Euston. Responding to Jason Groves’ inquiry into the mineral imaginary in his eponymous book, as well as the ‘Writing of Stones’ as proposed by writer and mineral collector Roger Caillois, the exhibition exposes the complex entanglements between the organic and the inorganic; the human and the lithic. 

Very happy to receive lots of positive feedback for my video installation Lithos Panoptes. People were very engaged with how the work reveals itself in stages, from the kaleidoscopic imagery displaying on the two way suspended screen to discovering the board of distorting lenses behind the screen and finally stepping back to see the original film from the human perspective before it is transformed by the lenses.

Referencing a many-eyed giant of Greek mythology, Argos Panoptes (always eyes still awake), the work considers the perpetual vigilance of rock as record keeper and witness. Video of human activity projected through distorting optical lenses transforms the anthropocentric position to imagine the perspective of the rock.

The pattern of lenses is informed by the molecular structure of magnetite, a mineral found in magma and metamorphic rock in Earth’s crust as well as in meteorites and the cells of organisms.

Through actual and metaphoric lenses, the relationship between the organic and non-organic is explored.

Mined magnetite is used in industrial and mechanical processes and its use in combustion engines and vehicle braking systems is releasing nanoscale pollutant particles into the air which are finding their way into human brain cells, vastly overwhelming the innate magnetite present, causing concerns linked to the development of degenerative brain diseases.

As well as referencing an ever watchful, many-eyed giant of Greek mythology, Lithos Panoptes also considers the numerous eyes (ocelli) of the chiton (a species of mollusc) whose rock crystal lenses have evolved over many millions of years to keep watch along rocky coastlines across the globe.

The only creature with eye lenses made of mineral and not protein, the chiton is also unique in having rows of teeth primed with magnetite which allow chomping on the hard rock surfaces it clings to. Some chiton’s teeth also contain the recently discovered mineral santabarbaraite, named after the mining district Santa Barbara in Italy where it was found – it is one of the few minerals named after a woman.

I was surprised to discover that the benedictions of Saint Barbara are still sought today, with shrines installed at tunnel entrances at Crossrail and even at CERN, the epicentre of scientific rigour. Before the boring machines were set in motion, services seeking her blessings were performed by local priests, with some even being winched down excavation shafts to carry out their duties.

Saint Barbara, who is associated with sudden death from fire, lightning and explosions, including military armaments, was adopted as patron saint of miners and tunnellers when the use of explosives in mining escalated during the 1600’s.

As the statues of Saint Barbara installed at these tunnel entrances are now buried, I have substituted images of my mother Barbara, coincidently born within hours of this Saint’s Day, in my video installation Lithos Panoptes.

Tucked into a dark recess of the gallery, Belly of a Rock suggests an imagined place of chemical conversations at the intersection of the organic and inorganic. A hybrid between rock, mollusc and technology this video sculpture responds to an early lifeform’s emerging self-awareness, desire to communicate and urge to create as described by Italo Calvino in his story ‘The Spiral’. We don’t always know what we are creating.

Thrilled to show these works alongside Julie F Hill @juliefhill, Rona Lee @ronaleeartist, Charlie Franklin @charlie__franklin and Deborah Tchoudjinoff @deboraht_ff

Julie F Hill’s sculptural print installation Parent Body uses scanning electron microscope imagery of samples recently returned from asteroid Bennu. The cave-like entrance, provides an embodied experience of the data and invites intimate contemplation of expanded scales. The ambiguous rock-like yet flowing forms echo the words of Jeffrey Jerome Cohen ‘stone is fluid when viewed within its proper duration’. Hill’s miniature work Return, considers the chemical and molecular cross exchanges between earth and space and in a gesture of reverse sample return (scientific missions and human extractive processes both take), a bead of Iridium is returned to the belly of asteroid Itokawa. Her small-scale embroidery work Water and Night, is based on observational studies of moonlight on water, continuing her explorations of water as the eye of landscape as proposed by Gaston Bachelard.

Deborah Tchoudjinoff’s moving image installation work The City of Gold (with sound in collaboration with Joe Farley) considers vast, beyond human, geological timescales when continents have once again become as one. Starting as a short fiction text, Deborah began to form an imagined world of cities in a future Amasia. The fictional cities are named after minerals that are heavily sought – rare earths, copper, uranium, gold, and coal – hinting at a narrative of an Earth depleted of the resources we rely on. The City of Gold is one of the five imagined cities. In a world where these natural resources are no longer, she questions what it would look like and who would be the inhabitants.

For Litho/Domous Rona Lee has chosen to work with book plates originating in the post-war period of the ‘great acceleration’ – a time in which population numbers, use of natural resources, popular consumerism, technological dependency and environmental degeneration burgeoned. Unified in their varying representations of the geologic but broking no contradiction between their celebration of extractive processes such as tourism and industrialisation and idealisation of the ‘wild’, the images selected by Lee conjure a pre-fall world in which imaginaries of lithic instability are firmly suppressed.

Two handfuls of silt (the residue of scientific samples collected at a depth of 4,000 meters), squeezed into the artist’s hands, fired and then gilded, form Rona Lee’s I want, I want, I want (2012), the title of which references William Blake’s engraving of the same name, wryly conjures the possibility of reaching down into the ocean’s depth, as though into a rock pool, while simultaneously cautioning against the folly and voracity of such ambitions.

The sculptures presented by Charlie Franklin, Landform and FRAGS, are lumpy, solid looking forms that speak of geological debris or ruins. All three pieces were soaked in the waters of the North Sea, on the easterly edge of the UK. This process allowed the natural elements to determine their individual patination or colouring, along with indentations and scuffs, where materials have been worn away by salt and stone. Cave Drawings (Aladdin’s Cave, Series of Grottos, Marble Curtain, Fairy Grotto, and Solomon’s Temple) are a series of five found postcards depicting the caves at Cheddar Gorge in Somerset, UK which have been hand coloured by the artist. Franklin is interested in how the addition of colour can provoke a personality or aura within each cave interior, allowing for grand experiments to be realised on an intimate scale.

A highlight of our events was an Urban Geology Walk led by geologist Ruth Siddall.

“The gravel pit, like other mining holes, is the reverse image of the cityscape it creates — extraction in the aid of erection.” Lucy Lippard

Ruth lead a group walk to explore the geology of the local built environment around Regent’s Place and Fitzrovia. Her knowledge of geology is astounding and her passion for stone infectious. Everyone came away incredulous, having their eyes opened to the deep time history of the rocks that build our city. The deep, black, Archaean dolerite from Mashonaland in Zimbabwe that Ruth points to is 2.2 billion years old. The large block of polished stone shaped like a giant pebble, itself crammed with pebbles of other rocks, is a sculpture by John Aiken, Monolith & Shadow. A patchwork of Jurassic limestone from southern Spain is crowded with the spire-shaped fossil shells of the gastropod Nerinea, stained red and yellow with ochres.

After the walk Ruth joined us for a tour of the gallery – it was fantastic to hear her insight and corroboration on some of the research that fed into the artworks.

I offered Lithomancy drop-in sessions on Friday afternoons as part of a programme of events for The Geological Unconscious. Visitors were invited to throw gemstones with specially assigned characteristics onto a wooden board divided into geologically themed sections. They are then given personal interpretations based on the position of the cast stones by drawing from the esoteric ritual of lithomancy which seeks to divine the future from the reading of stones.

This performative experience proposes insights into the power and allure of stones emanating from the symbolic meanings attributed to them and exposes the entangled relations between the human and the geologic found in our language and desire to align the human condition with the lithic.

We had many interesting visitors to The Geological Unconscious and have made some wonderful new contacts. Not least among these was meeting Melanie Wheeler who has recently completed a residency in the UCL Geology Department where she worked with the technician to re-curate the rock room. Julie and I were lucky to be taken on a tour of the newly curated collection and receive gifts. So excited to have a beautiful sample of magnetite.

In ancient Greek, magnetite was known as “magnes lithos,” meaning “stone from Magnesia” – the region in Thessaly, Greece, where magnetite was first discovered, supposedly by a shepherd who noticed the nails in his boots were sticking to the rock under his feet.

As an additional daily drop in activity during The Geological Unconscious we offered cheong tasting. Chef Moonhyung Lee explored human-mineral entanglements through digestion using stones to create cheong (Korean fermented syrup). The use of weighing stones helps create the environment for preservation, a process which amplifies the bioavailability of minerals in food. Moonhyung Lee is a food designer with a background in graphics. She is currently based in London and works at zero waste restaurant Silo.

It was great to have so many people join us for our Closing Event artist talks and the launch of the exhibition publication with preface by Jason Groves and short essay by Ruth Siddall.

We also had the microscope set up at the closing event to look at some crystal growth in solutions prepared by Julie who works extensively with crystals.

I had tried some ‘Vitamin C’ crystal growing microscopy experiments at home. These images use a polarising filter under the microscope to reveal the vibrant colours. Next step will be to set up a timelapse of the crystals growing.

Summer Solstice 2025. The shortest night of the longest day brought an awful darkness. Collected the last two solargraphs I had installed at the Hogsmill Nature Reserve. These have been collecting light from the sun for a whole year, recording every sunrise and sunset. May the light shine through.

I was delighted that my video Cosmic Chiasmus: crossing the universe was included in CARBON: Under Pressure, at the Mazumdar-Shaw Advanced Research Centre as part of Glasgow Science Festival 2025, in a special exhibition partnership with Science Gallery Bengaluru.

The video offers a glimpse into a subatomic world where cosmic rays travel from distant galaxies to collide and silently interact with atoms and technology on Earth. Alongside the screening of the video I was also invited to give an artist talk and cloud chamber demonstration. It was great to share the wonders of the cloud chamber with visitors who were able to see cosmic ray trails for themselves.

It is an incredible journey that cosmic rays make, blasted across space, spiralling along magnetic field lines to end up entangled with carbon in our bodies.

Not only is all life physically permeated by cosmic rays with the potential for nuclei collisions, but some cascading particles smash into atoms of nitrogen and combine with oxygen to create radioactive carbon-14 which enters our atmosphere. Plants absorb it during photosynthesis, and it is incorporated into their carbon skeleton, which we then eat. While plants and animals are alive, carbon-14 is continually replenished as the organism takes in air or food. But when an organism dies no more carbon-14 is absorbed and that which is present starts to decay at a constant rate. By measuring the radioactivity of dead organic matter, the current carbon-14 content can be determined and the time of death established. Cosmic ray activity gives us carbon dating techniques.

Reading

The Geological Unconscious – Jason Groves. Returning to this book that sparked the ideas we explored in our exhibition. A redirection of geology to consider a type of connection between things that are not in themselves geologic. Stones that stare, stones that speak. An image of the human could develop through geologic processes, becoming part of the mineral consciousness. Quoting Heather Sullivan ‘There is a difficulty for biology and philosophy to maintain a reliable distinction between life and non-life.’

The Writing of Stones – Roger Caillois. A paean to the capacity of minerals to form images within the imagination, which in turn is considered to be nothing more than an extension of matter.

The Performances of Sacred Places: crossing, breathing, resisting – edited by Silvia Battista. I read this for some background research while thinking about how I might make work responding to the abandoned sites of the cosmic ray detector huts at Haverah Park on the North Yorkshire Moors.

‘An horizon stands, in modern hermeneutics, for what is possible to see from the position of a specific observer. That is, not only a location in space but also a position in the cultural and historical apprehension of the world.’ Silvia Battista

The book opens by questioning relationships between the site and its ascribed attributes, which may be mercurial qualities not easy to define or quantify. It reflects on the performativity theories of Karen Barad which argue that matter, in its complexity, is an active participant in our relationship to the world and Jane Bennet’s call to recognise the ‘vitality of matter’ that crosses the human non human divide. In the section on ‘crossing’ the sensitive work of Louise Ann Wilson explores ritual around death, grief and loss through walking in rural locations echoing walking an interior landscape of memory. Walking the labyrinth and the pilgrimage are also considered as journeys that take place in physical and metaphysical space.
