I have a really pretty piece of Saint Just glass that was given to me by a really good friend who passed away. I'd like to make something with it but don't know the COE. Anyone know what clear glass I could use with it?

Thanks,

Don't.
Just slump it by itself.

Marty's right. Don't add anything to it.

If you bring handblown glass hot enough to full fuse, it will come out of the kiln looking much like Spectrum.

Bert,
If I just slump it, will it keep its characteristics and not change like you mentioned?

Thanks,

When handblown glass is formed, while it is hot and soft, it is only in contact with air, and the gizmo they use to give it striations. As you reheat it, contact with the mold will dull it. Heat will effect the striations as it gets hotter. So, if you do a drop slump or a slump with minimal contact, it can retain it's brightness. So, when you slump, fire only as hot as necessary.

It has actually been slumped during the manufacturing process in order to turn the cylinder in to a flat sheet. So, it can be done again if done carefully.
