[QUOTE="say_it_slowly, post: 62039, member: 50"]Looking at yours it's a bit hard to tell as they almost look like a white stoneware. I'll give you a little archaeologist's trick for telling the difference in sherds you might try. Both porcelain and stoneware are fired very hot and the clays vitrify and become non-porous (mostly) while pottery is fired at a lower temp and doesn't vitrify so remains a little porous. So here is the trick, if you have an unglazed portion, touch it to your tongue. If it sticks a little it's pottery, if it doesn't stick at all it's either porcelain or stoneware. (usually)[/QUOTE]
