When I glaze these French butter crocks, I wax the base of the lid inner lid and the inner corner that will rest on the main base inverted. These have to be fired separately since they could fuse together more easily. This can pose some difficulty with slight warping of the lid. Firing on a bisque cookie can sometimes help prevent the clay from snagging on the kiln shelf and warping. #pottery #potterystudio #studioceramics #wheelthrown #handmade #potteryartist | Alison Ryczek Pottery
