I am about to fuse some flat wire simple figure shapes between two clear 3mm layers of spectrum.

The wire is 2mm thick, and the sheets of glass fairly large 30cm x 40cm, I want to avoid large bubbles forming around the wire, so am thinking of using clear stringers around the edges of the glass to allow the air to escape, and also to use clear powder around the wire.

Please can anybody suggest a good bubble squeeze programme that would help? Any other suggestions gratefully received.

Thanks
Malcolm

I've never used Spectrum, but this was a successful programme for 20 cm bullseye circles with frit and stringers between the 2 layers of glass
