Hi! I'm Exquisite and I have this huge piece of art glass and I don't know a thing about it, can someone of your nice community help me please. The piece is 18" long, 13 1/4" wide and 13 1/2" tall. Thanks in advance for your kindness. I have a few pieces of art glass but unfortunately I don't know a thing about this subject and I'm new on the internet so I need a lot of help. :rah:
