We offer virgin runner/gating waxes with excellent mechanical strength, low melt points, low viscosities, and ease of use in assembly with excellent dewaxing properties. When switching to a system wax from virgin pattern or gating waxes, our technical support staff can help you evaluate the cost/performance benefits. Ferris Red Sprue This is our most flexible wax sprue rod featuring a regular hardness and a low melting temperature. Ferris Dark Green Sprue This is our hardest wax sprue rod, featuring our highest rigidity and stability. Ideal for the largest lost wax assemblies. These are wax lengths for bronze casting that come cored or solid, and red (standard) or green (harder). They can also be used as the armature when sculpting directly in wax for lost wax casting. 24in. lengths. SDS
