I have quite a bit of 100 yr old glass (large panes) and I'm not sure of using it in the kiln with other glass. I'm assuming that finding the COE is a difficult thing best left to the experts? - so, would you use it with other glass?
Are there additional health concerns -due to the lead content - when using it. I'm most interested in fusing, shaping and slumping.
Once melted or otherwise heated will it retain that wavy look that most old glass has?
Really appreciate this column - thanks to all.

you could sell it for restoration uses. you'd make a lot more money doing so.

once you heat it up, it will lose all the properties that make it look nice.

like he says. also it might turn milky after firing. been there done that was dissapointed. rosanna

Thank you both - I think I'll opt for using it for restoration work. Appreciate the info - saved me from ruining it.
