Hello everyone. I just purchased a studio from the widow of a long time potter. Part of the package was a large amount of a number of kinds of clay that I am not familiar with and was hoping that someone here had some experience with or knew about. Several hundred pounds of it is Great Lakes Clay MCL 343 as well as a few hundred pounds of DOM Porcelain and a few hundred pounds of Dave's Porcelain from Laguna WC384. I also have Amaco #25. Again, just looking to see if anyone has used any of this or knows someone who has and can give me an idea of what I am looking at.
