We can provide 2mm thick cut glass for framing, for those who want to assemble their own frames, at $10 per cut piece, up to 600mm x 450mm, and $20 per cut piece up to 1220mm x 920mm. We will cut to the dimensions specified, so please include your spacing in your calculations. We recommend cutting glass 4mm smaller than the dimension between frame bases. This gives a 2mm gap on all 4 sides, for fitting.
Note that it is not possible to "trim" glass. The smallest cut that can realistically be made is approximately 10mm.
We can supply larger glass or specialty low reflection glass on request, however, prices are substantially more, and will need to be quoted.
