Shidoni: Round Two

I observed a recent pouring back at the Shidoni Foundry. This is only one part (there are 10) of the lost wax bronze casting process. The below photos are from step 7, when the ceramic shell is removed from the kiln and molten bronze is immediately poured at a temperature of 2100-degrees Fahrenheit. Bronze is actually an alloy of 94% copper, 1% manganese, 4% silicon, .02% lead, .02% tin, and .06% zinc.
