The Large Round Box is almost double the size of the other box designs. Like the smaller boxes, the mold can be filled with frit, billets, or sheet glass. Create special pieces by lining the mold with collage glass, or by embellishing the lids with frit balls, decals, or other castings.
The two molds measure 8 x 3 and 7 x 1.5 inches (20 x 7.5 and 17.5 x 4 cm). Finished pieces are 5.5 x 2 inches (14 x 5 cm).
The fill weight of the base is 800 grams. The lid; 300 grams.
