I thought it might be useful to share my personal thoughts on the various clay bodies I’ve used and loved or hated.
First up is Standard Ceramic Co. #563. It’s a white stoneware, cone 6, no grog.
I really liked this clay from the first time I used it. In the beginning, it was a bit harder to control because it was so much smoother and responsive than what I was used to.
Having no grog, sand or grit, it burnishes very well if you’re into that sort of thing. I am.
It can be a bit more prone to S-cracks in the bottoms if you leave your bottoms a bit too thick or don’t compress them well, so pay attention to your technique and don’t skip steps.
I’ve not handbuilt with it, but others have said it doesn’t have enough grog (none) and is difficult to work with. Your mileage may vary.
