Firebrick Grog 0-5mm - 25kg
Description
0-5mm graded and dried firebrick grog. Suitable for the roman block method of mould making.
Crushed firebrick makes an excellent aggregate for a castable refractory, e.g. high heat refractory concrete. This type will survive in real high heat and can be used for hot-face applications.
The mix of Firebrick Grog, which is a refractory or heat-resistant aggregate, mixed with a heat-resistant cement, like Cement Fondu, is often referred to as castable, which is suitable for making pizza ovens and other outdoor ovens. The recommended mix of Firebrick Grog and Cement Fondu is 4 parts Grog to 1 part Cement.
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.
The primary safety hazard of firebrick grog (crushed refractory brick) is inhaling its crystalline silica dust, which is classified as a human carcinogen and causes lung damage. In the UK, you must manage this under the COSHH (Control of Substances Hazardous to Health) regulations and abide by strict workplace exposure limits.
Dispose of as normal industrial waste, in accordance with local/regional/national/international regulations.
