Foundry pictures

Here's "Go Fetch" at the foundry, getting the patina. The first picture is "naked - no patina has been applied yet. It's been sandblasted and residual patches of ceramic shell and fire scale have been removed. The patina is color resulting from heat and dilute acids reacting with the copper in the bronze. Patinas really pull the form together, adding a finishing touch. The chemicals and heat are applied, and, finally, wax is brushed on the hot metal to protect the patina.
