Does anyone have any thoughts on using Disodium Octaborate Tetrahydrate (Na=

B8 O13 - 4H2O) as a glaze ingredient? I have about 50 pounds of the stuff
left over from a project (fungicide/insecticide used to treat the logs I
built my home from), and rather than throwing the stuff away I thought it
might make a good ingredient for raku glazes. It seems to be somewhat
soluble, which gives me pause, but it melts at only 1500 degrees F. Any
ideas?
Thanks.

Would calcining create sodium teraborate create Borax? I use
borax in my crackle slip.

Lee...
It seems to already be a close cousin of borax, but with less oxygen and
less water. My guess was that it was close enough to be useful, but didn't
know if there was any chemical or physical weirdness about it. Perhaps a
side-by-side test is in order.
Take care.
