I posted a rant on a lampwork forum today, because I was really badly burned by a chunk of molten glass that attached itself to my 'upper' chest area. I mean really attached, in that I had to pluck the glass away from my flesh, and tear the skin.
I can't tell you how much this hurts....you sort of have to be there. The thing is; there is, at the present time, not ONE reliable clear glass in the 104 COE line. Not one.
Most soft glass artists get it....we've been fighting this battle for years. Just how hard is it to give us clear glass??? Suppliers give us endless "odd lot" garbage, (otherwise known as 'mistakes' that they suck artists into paying huge $$$ for), but they just can't seem to manage the one thing that we want, a dependable, compatible, non scummy/seeded with crap/bubbles clear glass.
