This is made from a recipe promoted by a popular website (equal parts of talc, ball clay and grog). Are they serious? How could the page fail to mention how coarse this is? How is it possible to throw something like this. Wouldn’t ware be porous and weak? Is this an attempt to make cordierite? But that needs special firing. Maybe the idea is that anything with this much grog can automatically be ovenware!

Ovenware
Ovenware clay bodies have a low expansion by virtue of materials in their recipe and/or the way they are fired. But potters bend the rules. |
