Angelica Sandoval’s Awesome Sculpture Class Metal CASTING

Casting via the Ceramic Shell process

One of the truly exciting experiences for JCCC students in Sculpture is the casting process.

This intricate, multifold process starts with an idea, which then the student makes a “positive” of using microcrystalline wax. Once made, a wax “sprue” (channel for the metal) is attached. The entire solid piece of wax is then dipped multiple times into a silica slurry, which builds up a “ceramic shell” around the wax. After the shell has dried, it is fired and the wax is steamed/ melted out, leaving a void in which a metal is then poured, such as aluminum or bronze. The shell is then chipped away, leaving the “positive” metal piece, whereby the sprue is removed and the sculpture is cleaned.

Before removing the crucible from the furnace, Angelica skims a mucky “slag” or waste from the top. Leaving dirty slag can cause ugly pitting in castings.

The crucible is attached to a hoist/ crane which makes lifting the heavy crucible more manageable.

NEWS! FIRST FRIDAYS: Student Show in KC XROADS
