The glare from the overhead light makes this piece of glass appear irridized, but it is flat black.
A better picture shows in the listing on etsy
If you know anyone that works with glass you might want to pass the information forward.
I have TONS of glass and can create a custom box for their particular use.
Scrap glass is wonderful for small projects, such as box making, jewelry parts, experiments...
to use in fused work...if you already work with glass, of course this is familiar to you..but if you are just beginning! and have found out how expensive glass is even for a small 7x7 sheet, you can appreciate the scrap box source.
These sales begin at 10.00 dollars on ebay bidding links...none i saw had nice chunky pieces as I can offer.
But I have the small stuff too.
Help me out if you will and forward me to anyone who you think can benefit of my offer...remember I will customize the color selection, and if a large piece of glass is desired I have that too.
