Bloating can happen suddenly
Monday 21st July 2014
Example of a buff insight-live.com/glossary/85">stoneware clay bloating at cone 10 oxidation (whereas it appears very stable at cone 8). This is a 25x4 recipe employing 200 mesh silica, feldspar, kaolin and ball clay. The cause of this is not always obvious (the body should soften and melt without bloating). This body is fine for the production of ware to cone 8 but obviously, kilns must not be permitted to over-fire.
