Silica is the main glass former in ceramics. It is added to clay bodies and glaze recipes when the other materials do not add enough silica to the mix. The material is sold in two different meshes, 325 and 200 mesh. This product is 200 mesh which is typically used for clay bodies.
For decades, we sourced our Silica from US Silica's Illinois Plant. As their prices skyrocketed, we inquired with other clay manufacturers and suppliers and found Short Mountain Silica in Tennessee and with the help of Kentucky Mudworks who connected us and vouched for us, we were able to switch our silica source. We take material source changes very seriously, and we compared the analyses of all our silica products and tested to ensure there would be no noticeable difference. The only thing you should notice is that the bag looks different.
