Our 4" Glass Dam is machine-pressed and will easily contain several layers of glass. The smooth texture will create smooth edges on you finished glass art. We have multiple sizes of glass dams so you can create any dimensions of thick fused glass art.
Layer several sheets of glass. Place your primed dams on the outer edges supported by Hot Bricks into your kiln and fuse.
