Amazing, thank you all for your help!

Great, thank you for your help! Would you recommend replacing it with anything to round out the recipe?

I am wondering if anyone has advice about how to help with the increased melting fluidity of the Gerstley Borate substitute, Gillespie Borate. It's an almost exact 1:1 substitute, but is slightly more runny in some glazes. I work at a large and busy community studio, and since 9 of our glazes use GB and now need Gillespie Borate, I worry that it will create a chaotic drippy mess throughout the kiln. Luckily, other than the increased glaze movement, the glaze tests with Gillespie Borate seem otherwise great. Does anyone have any slight changes or additions/subtractions to help with the Gillespie Borate that won't drastically change the overall chemistry of the glaze?
