An Excellent Beginner Project Create elegant custom glass tiles, coasters and fused pieces to incorporate into larger glass art projects. Simply fill the mold with fusible glass, frit, enamels and metal inclusions to make your own unique designs. Make complementing tiles or a matched set to complete a mosaic back splash, table top or more. This sturdy ceramic mold is designed to last through many firings, and fits easily into a table top kiln. Overall dimensions are 5-1/2" x 5-1/2" x 1-1/2". Creates tiles that are 4" x 4" x 1/2".
