It shows no evidence of boron physically. I do think it's a beautiful glass. Perhaps it has lithium, I simply don't know. It is a good deal more expensive than Spruce Pine but so is my formula.

If any decent stateside cullet maker came along making a batch glass into cullet that had good working properties, it would knock all of these products off the market. It would take a minimum of a half million dollars to do it initially, likely more. Importing cullet or batch from Europe is not a sane proposition.
Where are we going and why am I in this basket?
