not sure how bad your bubbles are, but I sometimes squirt diluted alcohol which breaks the surface tension of the bubbles...at least the ones floating on top. I learning this from plaster mixing with Richard Notkin who learned it from professional mold makers. It does not have any effect on the glazes.

Thanks for the tip Marcia but this isn't to do with application issues. Will try it next time I am making plaster moulds My problem is with the LOI leaving bubbles in my fired glaze.

when i sub wollastonite for whiting/silica the glazes flux more when the formulas are balanced. i need to slightly undersupply the calcium part of the original formula.
