The miniature bowl mold provides several possibilities of creating small glass bowls. From the interior of the bowl mold you can make small slumped bowls from 1.5 inches to 3.5 inches in diameter. And the bowl mold can be placed upside down to provide a mold for draping your decorated glass disc over the mold. The small sushi mold is designed to make small sushi style bowls up to 2.5 inches square.
