These are 35 LB bronze ingots - each panel uses 10

The linen is wrapped around an aluminum panel, then cast into a sand concrete mold

The sand concrete mold has a top and bottom lid. It is engineered with internal "ducts" so molten bronze fills the void between top and bottom before the molten metal cools

Then the molten bronze is transferred from the furnace to a poring vessel

Then the molten bronze is poured into the mold, flooding the void until it spills over the top

After the panel cools for 3-5 days, the surface is lightly wire brushed to remove ash from within the mold and reveal the beautiful coloration of the bronze
