Our Glass We offer an extensive variety of art glass manufactured for the stained glass artist by Spectrum, Wissmach and Youghiogheny. We also carry select art glass by Uroboros, Desag, Pilkington, and others. If you visit our store and browse around for a while, you will also find some very old and unusual glass that we suspect you wont find anywhere else: from Blenko, Scott Glass, Advance Glass, and a small German company whose name we cannot spell. This glass is offered in rectangular pieces, typically in pieces weighing one pound ( 8"x12" ) or two pounds ( 12"x16" ). All of our glass is also available in full sheets. Spectrum Glass sheets are typically 24" x 48", Wissmach Glass sheets are typically 32" x 42". Youghiogheny All of these glasses are available at our warehouse in Rockland, Mass., for pickup. We welcome your inquiries. We can also ship this glass by common carrier.
