raku'd all morning & then I get into the kitchen tonight and burn my hand from the steam of a microwave dinner. Looks like I should have kept the raku gloves on.

Starting to read thru the gerstley borate substitute items on the forum. Has anyone tried Tom Buck's dry mix substitute? Or do you think its less problematic to just go with Gillespie Borate?

Back in the day, one issue with Gerstley was its variable chemical content. Natural materials are always variable over time , depending on what part of mine it came from, etc., but Gerstley was variable from batch to batch, and some even gave it the nickname Ghastley Borate. When Laguna bought the whole mineyard (but not the mine, nothing new coming out of the ground anymore), they processed it all at once and thoroughly mixed it all. So now the many years worth stock in the warehouse is all pretty much the same. But also slightly different than what it was 20 years ago. The published analysis of the current stock compared to ~1999 show somewhat less silica than before, but other fluxes are about the same +/-. So get some Gerstley and make a test batch of your glaze recipe to see if it needs any tweaking.

another evaporite mineral! - I just bought a 50 lb bag of Laguna Gerstley Borate so I didn't need a substitute. Started mixing up glazes today. Will add a few touches to the raku kiln in the morning so I can operate it by myself, then I'll have more pictures for the gallery.

Got my new tiger torch today. There was a problem with the valve on the old one & the regulator was slowing things down. I think its all a-ok now
