The Poetics of Fire

The Poetics of Fire; the soda-fired vessels of Jack Doherty

Article: The Journal of Australian Ceramics | The Flame Issue | July 2017


Breathed by dragons, run through the streets by Olympic athletes or simply to be gazed into on a midwinter’s night. Fire is indeed the most primal of forces. One of the four elements in ancient western culture it is believed to be fundamental to life; it is also the most unpredictable, volatile and capricious.

The French philosopher Gaston Bachelard says in his writing, the Poetics of Fire “fire is the element in the centre of all things.” Universally it is at the heart and hearth of many creation myths from the beginnings of time; cultural, traditional or religious, mankind has envisaged the world formed from flames. Creation comes from a state of chaos.


The symbolic reading of fire evokes a powerful image. It can represent pure spirit, vitality and passion but also brutality and destruction. In character it is both passive and active with the ability to bring change. Greek mythology differentiates between the destructive fire associated with Hades, the god of the underworld and the creative, benevolent fire connected to Hephaistos, the god of blacksmiths, sculptors and craftsmen. From industrial manufacture to contemporary arts practice, the forge, the foundry and the kiln harness the raw energy of this natural resource for practical and creative application.

Irish potter Jack Doherty makes porcelain soda-fired vessels. His work is concerned in a way with function; containing, holding and storing, but not necessarily utility. He describes them as revealing qualities of art and utensil. He states “I am intrigued and inspired by the potency of archetypal vessel forms. Anonymous and uncomplicated pots from pre-history used for storing, cooking and keeping people safe through winters and giving protection in the everyday world can also function in other ways. I see them as figurative objects. As guardians of emotion and connectors with the spiritual, I want my work to inhabit our domestic spaces in the light, shadow and darkness with qualities that neither painting or abstract sculpture can.” Over the years his working process has become simpler and more refined in the belief that stripping away what is unnecessary can produce work with complexity and depth. His work is made using one clay, one colouring mineral and a single firing.


For Doherty the kiln is a practical tool. It is also the subject of an intimate relationship, a skilled and finely tuned process delicately balanced between science and art. Fire is the essential collaborator in his creative process. It becomes the catalyst for change, a transformer, converting objects into other forms, through heat, flame, smoke and soda. An interdependent partnership at it’s most primal; artist and fire working together.

“He knows his kiln; they have been together for a long time. He plays the kiln for hours, stifling it until the flame darkens, then flooding it with air, and all the time he is teasing the copper from his pots. She is his element, the source of colour in his work, but flirty and volatile, never settling, always wanting something else.”
— Craft Historian and writer, Dr Eleanor Flegg describes this special connection in her article Troubled Light (Ceramic Review 261)

Firing is a focused and demanding process. Doherty adds that this personal dynamic in the relationship with the kiln is also a very grounding and pragmatic experience. He says “I try to ditch all the emotional stuff. I have designed and built each of my kilns. I carry the responsibility if it doesn’t work. The technical side of my work has focused on using soda, gas firing and the space within the kiln as a vital creative element in the process. I use soda firing not to replicate the qualities of salt glaze or wood firing. Instead I have experimented with many materials in order to develop a new palette of colour and surface texture closely integrated with the form. The colours are developed by alternating the kiln atmosphere between oxidisation and reduction, blasting the surface of the pieces with the sodium solution at high temperature.”


In Doherty’s studio there is a shelf of well-thumbed kiln diaries listing all of his firings dating back to the 1970’s. From these tentative experiments into soda-firing they record every detail at every half hour intervals. They note not just gas pressure, temperature rise, failures and successes but weather conditions, timings, sketches and drawings.

This is the memory bank where a potters knowledge is stored; a resource or library of accumulated skill and technical experience. His work does not stand still but evolves and expands. Doherty says “I want to make all of my processes add to the nature of the finished piece and to be brave enough to not stand still. The hour or so that I spend spraying the soda is probably the most concentrated and focussed of my life. There is no need to talk. The job here is to work the chamber, directing the sodium solution through and around the silhouetted forms into the gaps and spaces. This physical connection is as close as I get to making with fire.” There could be an assumption that the kiln does the work but here is a potter working with the interaction of the flame, the spaces and atmosphere of the kiln, like a performance or dance, working in harmony as a musician plays his instrument.

Doherty works in porcelain, a clay most commonly associated with fragility and translucency, he utilises the quality of whiteness and brightness to compliment the simplicity of his vessels. There is a vulnerability to these simple un-fired forms clustered in groups in the kiln chamber. They are exposed to extreme heat and danger as the flames move around the pots like water flows around rocks in a river. Subjected to the trauma and fierce atmosphere, there is a significant amount of risk involved. Fire commands respect and can be very unforgiving.


The nature of working closely with this complex unpredictable process of channeling fire Doherty says is not about magic but about vigilance, memory, time and patience. He describes his intentions:  

“For me firing with flame and soda is a dynamic way of making ceramics where the kiln is an exciting and essential creative environment. Sometimes I gently caress the forms, enticing and teasing colour from the copper. Sometimes blasting the pots with the sodium solution, etching into their surfaces almost to the point of destruction.”
— Jack Doherty

Michael Moore, head of the Centre for Applied Arts Research at the University of Ulster writes, “These works to me seemed to be survivors. But not in a defeated sense, more that they had emerged from the ferocity which fire and soda can impart combined, with dignity, to create absolutely bespoke forms and surfaces.

Through the potentially destructive turbulent firing cycle the work is brought to life. Doherty’s bold and elemental pots are scarred, engulfed and marked by the fire that brings beauty to the forms through nuances of subtle colour and textured surfaces.
