Rubber Sprue Bases are a must have for casting gold, silver or any other precious metal jewelry. These bases attach to a solid or perforated flask. To use a rubber sprue base, you must melt wax into the center hold and then either add a sprue or attach a wax model right to the dome base. Sprue bases assure a leak proof seal when casting.

Available in Cone type, and vary in sizes:

-Sizes: 2-1/2", 3", 3-1/2" and 4".

-Height: 1".
