Description

A good all round fireclay in granular form giving excellent stoneware properties. This product is in a raw, as dug state which is dried and pulverised. It may still contain some oversized particles.

Extensively used in all places like glass melting furnaces, boiler furnaces, chimney linings, pottery kilns, blast furnaces, reheating furnace and outdoor pizza ovens. Refractory cement is much more expensive than powdered fire clay, so this is the cheaper and does the exact same job. Excellent gap filler or leveller before bricks are laid in either kilns or oven. This material can be used to make your own refractory.

Health & Safety & Disposal

When handling powdered ceramic materials, you must wear an FFP3/P2 face mask and nitrile gloves to prevent inhalation and skin contact.
Wear a wipeable apron, polyester overalls, or similar. Clean or wash frequently.
Always clean your studio with a wet sponge rather than sweeping to stop dust from becoming airborne.
When preparing glazes, add the dry material to water, not vice-versa, to minimise dust formation.
Do not allow eating and drinking in the studio and thoroughly wash hands when leaving.
Never eat, drink, or apply cosmetics in areas where clay or glazes are handled.
Ensure emergency eye-washing facilities are available in the room.
Review official guidelines regarding studio ventilation and chemical management routinely.

Powdered fireclay is a hazardous substance primarily due to its respirable crystalline silica (quartz) content. Prolonged inhalation of dust can cause silicosis and increases the risk of lung cancer. Under UK COSHH regulations, it must be labeled and handled with strict dust-suppression measures.

Dispose of as normal industrial waste, in accordance with local/regional/national/international regulations.

"The service was quick & professional & comprehended the importance of making sure the clay arrived in perfect condition, the courier on the other hand was rude & disrespectful because their email arrived after you go out/to work (unlike most who email you the day before) & wasn't happy they had to come back,"
