Hi,
Over the years I have acquired fancy furniture that has this form fitting glass surface. This 1/4" glass presents a tremendously hard and useful surface.
But brittle.
I've made a few inquiries and local mirror shops seem to be the established businesses fabricating exact replacements.
But, always one to save a nickel, is there something out there that is "DIY", "do-it-yourself"?
Maybe a very high quality thick plastic that you can cut with special tools... ?
