Water white glass?

[Not your average framer]

I have a number of part sheets of what I believe to be one of the many varieties of water white glass. I got these as part of a job lot from a framers which closed down and I've never used them as I don't know for sure what it is I've got.

Can anyone offer any advice on how to identify what I've got please,
Thanks,
Mark

Look at the cut edges, if they are 'white' compared to the green of standard glass, it's water white type. If it has an optical coating then that should be obvious, but as they are offcuts and if not individually wrapped, if they have any sort of coating, optical or UV, they'll probably be scratched. If not and the edges are 'white' it could be WW Denglas.

Thanks John,

That confirms what I was thinking. Fortunately they are good sized pieces, mostly half a 3ft x 4ft sheet or more, so they are all usable.
