Building a casting tree calls for a sprue wax soft enough to bend by hand and firm enough to hold a heavy pattern where you set it.

Ferris #12 is a soft red sprue wax for building sprues and runners in lost-wax casting, formulated to flex easily while still supporting complex wax patterns. Ferris #12 red sprue wax is the best-selling sprue wax on the market. Sprues bend smoothly between your fingers and stay exactly where you place them on the tree.
