Stoneware at cone 02? Yes. These test bars are fired to cone 02. The top body is 50:50 Redart and a silty raw material from Plainsman Clays (named 3D) plus some bentonite and 1% iron. The bottom one also has 5% Ferro Frit 3110. The porosity: The bottom one is 3%, the top one 8%. So each 1% frit reduces the porosity by 1% in this case.
