Do you want 12 x 16? Or is that an approximate size?
Anita, for you - I will go through my glass and put a box of 12 x 16 aside for you and meet you somewhere south on my way to Grand Prairie or Duncanville in a few weeks on a Sunday or Monday.
You are welcome to as much of the regular glass as you want.
I plan to clean out the glass storage rack in the next 60 days.
Most it will go in the dumpster.
The glass I use is what one would find in custom picture framing. It is clear, most is coated other than the plain glass that Anita uses.
This clear glass that Anita uses/picks up is not what I typically use, but like many things - it accumulates and a purge is the next step. Most of it is 2.0mm or 2.5 mm thick.
I have a local friend that operates a stained repair & restoration company. He “fixes” them - I just frame them. If you are interested - see the link below.
