Hi all,
I was wondering if there is a way to identify acrylic (cast or extruded) if it does not clearly state it on the paper or plastic masking. Most of the acrylic I see in hardware stores just say acrylic or plexiglass. Some have a blue plastic covering, and others have a paper covering. I have etched and cut out a 16x20 photograph on some .236" acrylic found at a hardware store. It came out great. The etching was a little on the lite side.
Thank you.
