A casting method where molten metal is poured into a permanent metal mould, allowed to partially solidify against the cool walls, and then inverted to drain the remaining liquid core. This technique produces thin-walled, hollow parts without using an internal sand core. It is primarily used for low-melting-point alloys like zinc or pewter to make ornaments and lamp bases.

We slush-cast these zinc figurines to save on material weight and avoid core making.
