Part 1 of 2 - Turning Dollar Store Balloon into Bronze Metal Sculpture

In this first part of the lost wax foundry process, a dollar store balloon has a silicon mold made, wax duplicate created, sprued, ceramic shell coated, lost wax burnout and then finally cast in bronze metal. This is the first half in a two part series; next the Balloon gets sandblasted, de-sprued, welded back together, mirror polished and painted.
