  1. Thanks,John I really don't know how to find all those products! I live in Brazil, and here the places where they sell those materials don't know much about its chemistry, and I'm a begginer also... So I'll try my best to find all these 'low iron ball clay"... I do have the Potash feldspar, which I've used... What means thixotropic? Thanks for answering! Pat
  2. Hi! Thanks for the tip, but what should I remove? to increase more 20% of clay, to make a recipe in porcentage, I'll need to remove some part of some elements... Thanks for answering! Bye, Pat
  3. Hi, I'm trying to produce my own porcelain. I began with the most simple recipe 15% Caolin 15% white clay 60% feldspat 10% flint It's to cone 6 1.230° Celsius It stays really white but not to plastic, not flexible, it cracks when I try to bend into a plaster mold, and if I add more water, it turns into mud. What can I do to correct and have a more plastic porcelain so I can have a very thin wall. Hope someone can help me. Thanks, Pat
