Place cover sherds (broken pieces of pottery) over the pots to keep coals from the fire from falling down and contacting the pottery.
What is silica sand used for in pottery?
When manufacturing ceramics, the use of silica (SiO2) helps modify thermal expansion, regulate drying and shrinkage, and improve structural integrity and appearance. Silica is necessary for both glazing and body construction of products such as tableware, sanitary ware, and floor and wall tiles.
What is silica sand?
