    I’m new to this forum, and I’m desperate for help.

    What other manufacturers are there than bullseye that sell glass suitable for fusing and slumping?


    I stay with Spectrum and Bullseye – you can find them here:

    There are a few others, but I don’t know much about them.



    In addition to Spectrum and Bullseye, Uroboros manufactures fusible glass, and Armstrong has fusible float. Make sure you are combining glasses that possess the same COE. Bullseye is 90COE, Spectrum is 96, I think Uro does both, and the float is 82.

    For variety of colors, Bullseye is your best bet. For cost and ease of cutting, you might prefer Spectrum (and they have a fairly wide color pallet too).

    My issue with Armstrong “float compatible” products is that there is no one COE for float – it varies from manufacturer to manufacturer (and even from lot to lot) which makes sense when you consider how difficult it is to keep it consistent and they have no reason to try. There is a reason Bullseye tests every tenth sheet.

    So, if you cannot guarantee compatibility between two random pieces of float glass, how can you claim to make a “float compatible” product?

    I agree, Paul. Have you ever had a chance to work with it? I don’t think I’ve ever heard anyone’s experiences with it, and I haven’t worked with it myself.

    A newer 90 coe glass on the market is Wismach Glass, Paden City, WV. Their glass is a lower cost alternative and can be seen here:

    Also they are working on a 96 coe that will be compatible with Spectrum, not too far off from what I am hearing.

    The Wishmach dichroic is outstanding, lots of different textures with nice dichro coating done by CBS.
