I have searched, but can't find an answer for this one.
Is it possible to use colored glass, say from old vaes, glassware (some is quite thin) for tesserae?
I have several pieces in colors, but wondering how to safely cut and use it.
Will wheeled cutters work on this type of glass?
Is silicone ok? I want to do the outside of a glass vase so the light will shine through.
