Amazing Glaze Food-Safe Recipes: Innovative, Lab-Tested Techniques and Recipes (Mastering Ceramics)

I recommend reading the new edition of Amazing Glaze, which dives into food safe recipes and discussions of what makes glazes stable or unstable!

Get this book, and make anything out of it that you want for your cone, knowing that it will be food safe in all circumstances (properly fired that is) for your members: https://a.co/d/0jbDYpUu
