Rubber Sprue Bases

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 Well or Cone type, and vary in sizes.
