Stiff Wax Sprue Rods - Light Green

These light green wax sprue rods serve as the main structural support for building jewelry casting trees. The 90 lb hardness rating ensures that the rod remains rigid and straight even under the weight of many patterns.

The specialized wax formula is designed for a low-ash burnout to guarantee a smooth and clean metal surface. Its light green color provides a high visual contrast against standard blue carving waxes for easier tree inspection. These rods are an essential supply for any casting department that requires a solid foundation for their investment molds.
