Probably all you'll need to know. And recipes, to boot.

I chose the best throwing body I have, but I don't know about the grog.  It is Redstone, From Highwater. very happy to stand up tall and get thin.


Highwater's description of Redstone: "This is a rich, reddish brown body with a lot of character, warmth and excellent working properties. Use for hand & wheel work. 6% fine kyanite." So, it may not be the smoothest body. Kyanite has good thermal shock properties.

The low fire clay was probably grogless; your stoneware clay likely has grog. So, you are comparing apples and oranges in terms of clay bodies. You can find stonewares with no grog which should make the folding process more comparable. Another factor is keeping the clay moist while being manipulated. The will be some differences due to firing temperatures. Low fire shrinks less and will likely hold the shape more; stoneware fires higher, shrinks more, and could result in some distortion/warping -- hard to tell without seeing the form in question.

Glaze thickness/glaze too stiff. The glaze is too thick to flow into the sharp corners; it looks like it is covering after being dipped and then drying, but it is not actually making contact underneath with the clay surface (pocket of air). When it fires, the glaze shrinks and exposes the claybody. I've had this happen with majolica base glaze.
