Shown below, sprues (funnels) and gates (vents) made of wax are added to the wax casting. This creates channels
for the molten bronze to enter and an outlet for the escape of the lost wax and gases. The process is called spruing and gating. This procedure is more easily understood as I continue discussing the lost wax process in the next posts.
Note, the red wax chasing repairs. Also, the wax "patches" were removed to enable the bronze to be cast hollow.
The patches will be welded on later during the bronze welding and chasing process.
