Now cullet --such a pretty word--is ground glass. And ground old glass =
is a constituent in making NEW glass--or so I have been told over and =
over again. Therefore a factory that makes glass, such as a factory =
making beer or soda bottles, possibly even one making window panes, and =
like that, should have some cullet. And I expect a small amount--like =
50 lbs--should be obtainable. Cullet, I imagine, is also used in making =
other stuff...NO IDEA...but a factory making whatever might part with =
some.....

Lili,

I have made cullet from beer botttles, wine bottles, old window panes, soda pop bottles, and just about any other glass I can find. Yes, it is possible to buy 50 pound sacks of cullet (I don't know how finely ground), but consider this... Cullet is simply a high-soda frit.

Cullet is also used extensively in many of the old so-called "folk" glazes in Appalachia. Most of these glazes call for such recipes as:

bucket of ashes
bucket of crushed bottles
bucket and a half of river mud

Pretty simple!

I have used cullet in making tile glazes. Crushed and ball-milled green wine bottles, mixed with a little EPK make a wonderful grass-green crackle. I gave my brother a tea tray with tiles made this way. He and his wife use it every day.

There are some blue wine bottles I'm saving for making some special tiles, and some brown ground-up beer bottles. Again, this craft of ours is limited only by our imagination.

I will not live long enough to try it all...

See YOU at NCECA!
