[Clayart] White stoneware and handles

[sumi]

Paul

the idea is that if the mug is not vitrified it will over time and 
repeated washing absorb water into the clay, which will then cause the 
handle to heat up. Not a new mug straight out of the kiln.

>> I stick with white stoneware because I’m a color junkie and glazes are brighter and the colors more intense when used on a white clay body. I’ve used chocolate colored clay because …. it was chocolate colored and I like trying new stuff. Personally, and I don’t care what anyone else decides because this is my decision and it works for me, I don’t particularly care for chocolate clay. With such clay you get…. brown. Just brown. Try putting underglaze or colored glaze on a chocolate clay pot, and the color disappears. It’s interesting to experiment with chocolate clay, but 50 pounds is a lifetime supply.
