Thanks! I actually own that book, but it's been unhelpful -- the in-depth sections are largely about detailed stability and durability testing, which isn't my major concern. (We're primarily serving beginner to intermediate students, so my first priority is glazes that just look cool and fire consistently; professional-quality pieces are in the minority, so durability isn't as big a deal.) The other tips feel scattered and incomplete. It feels like the book is meant to plug common holes in the knowledge of a slightly miseducated reader, but I don't have that knowledge to begin with.
I'm looking more for a resource that might help me understand, what makes this glaze glossy and that one matte? Why does this glaze do cool things when I layer it over other glazes? What might I try if I want a glaze to crawl less? What's calcium carbonate for? What makes a celadon a celadon?
Is there a decent textbook or something? I had The Potter's Dictionary of Materials and Techniques out from the library for a while, which helped, but was kind of hoping for a reference focusing on glazes specifically.
Or am I better off buying a piece of software and just using their tools and reference libraries? (John, thanks for those links as well.)
