How Pit firing is used

The artist forms and thoroughly dries the clay, often burnishes it or applies terra sigillata, then may bisque-fire it at a low temperature. The work is packed into a pit, barrel or fire ring with wood, sawdust, leaves, salt, minerals, metal oxides or other combustibles. A fire is built, allowed to smoulder or burn down, and the pieces cool gradually before cleaning and sometimes waxing or sealing.

What Pit firing looks and feels like

Organic smoke trails, flame flashes, carbon-black areas, warm red, orange, pink, brown, grey or silver tones, irregular mineral staining, ash deposits and exposed raw clay. Surfaces may be matte, satin or glossy when burnished, with highly variable markings and occasional firing scars.

Commission applications

Decorative vessels, sculptural forms, memorial objects, abstract wall pieces, ritual or contemplative objects, rustic interior accents and bespoke gifts. The technique is particularly effective when the client values natural variation, symbolism and a one-of-a-kind surface rather than exact replication.

Suitable for

Gifts, Home interiors, Wall art, Sculpture, Memorial, Garden, Public art, Hospitality, Retail display, Events

Materials and practical considerations

Low-fire or grogged clay, earthenware or suitable stoneware; terra sigillata, slips, burnishing tools, wood, sawdust, leaves, straw, salt, copper or iron-bearing materials, dung or seaweed where appropriate, metal sheeting or a saggar, and optional wax or acrylic sealer.

Durability and care

Sintered but generally porous and lower strength than fully vitrified kiln-fired ceramics. It can be vulnerable to impact, frost, prolonged moisture, staining and abrasion. Treat as decorative unless the artist specifically confirms a suitable clay body, firing temperature and sealant for another use.

Questions to ask before commissioning

Buyer guidance: Expect every piece to be unique, with limited control over colour, marking and survival during firing. Finished work is usually porous and decorative rather than food-safe or watertight. Confirm whether the artist will make a single piece or several attempts, how breakage is handled, whether the work is sealed, and whether delivery, outdoor-fire permissions and installation are included. Buyer questions: Is the piece decorative only or sealed for a limited practical use? Was it bisque-fired before the pit firing? What clay body and surface treatments were used? How much variation should I expect? Will the artist make more than one piece to account for breakage? Can I request a colour direction without expecting an exact result? Is the piece suitable for frost, rain or direct sunlight? What care, hanging hardware, packaging and delivery arrangements are included?
