Single fire. SV1 glaze
My research indicates that an amount of boron equal to or slightly exceeding the amounts of alkaline earths should be alright.
These pieces were glazed with a single-fire version of one of the glazes I am testing, to give a preliminary indication of fit.
The formula of the glaze (the same one on both body tests) I therefore see as immaterial in this study of boron in the body.
The glaze shows an interesting aspect of SS 2A & 3, in that it was absorbed into the body -- I take it that this was due to over-firing.
SS 1 & 2 -- using 3110 -- show good preliminary results, but SS 2A & 3 give me reason to doubt continuing with boron trials.
Body SS 3 is markedly bloated, likely from the early melt of the frit (it employs frit 3134). This was cauthioned in research.
Evidently, others have successfully done, but it may involve too deep a study to be worth while for me.
