Found this beautiful piece just looking for someone to take it..
...so I did!! Now its safe and sound and loved at home. Im a very beginner in stained glass knowledge and never even held one or touched one before let alone had one at home. I understand the process of it, and thats why Im here to ask - since we make them from pannels, it should be bumpy with copper from both sides...no?
This piece right here only has copper on the front and the back is ENTIRELY smooth. Also confirmed, it is real glass (has a huge crack through the entire top of it + glass texture like this cannot be replicated by plastic I believe).
Why is it like this?? And how can i maintain it/mount it into places safely?
