4" x 1 1/2" deep Stainless Steel Casting square
This heavy duty 16 gage square is great for casting extra thick glass to slump into plates or bowls. The 1 1/2" deep square is oversized by 1/4". So after you use fiber paper your piece will come out full size. You can also do pot melts into the square to control the glass. A great way to use those small scraps. Just use on a primed shelf or shelf paper. Primer square and allow to dry. Place fiber paper on inside walls of square. Pile in scrap glass and cook. Square will last a very long time.
