Potters & Sculptors - Making Rock from Mud
I just started making my own glazes again this year. Before that, it had been about ten years. At that time, Gerstley Borate and Kona F4 Feldspar were still being mined.
Many recipes still call for these. My understanding is that people have many different opinions on substitutions. My local pottery uses a straight one-for-one substitutions with Gillespie Borate and Minspar.
I'm curious what your experiences have been.
WOW! What a great resource!
Hi Shine. You may have solved your Gerstley Borate questions by now but I came across some stuff called Laguna Borate. Which I think was made to fill the gap created by the absence of Gerstley. When I make the one for one exchange on my Digital fire software the chemistry is very similar. I have not fired a tile yet to compare visual results but I will soon. Happy firing
thank you--- sorry for the extremely slow reply
