Here is a mold opened up, it has two cardboard patters in it for legs for the bench. In the top right of the picture you can see molds that are ready to pour.

The patterns are removed and I have cut channels into the mold to allow the bronze to flow into the pattern and there are vents to allow the air to evacuate the mold quickly.

The mold is now glued and banded together. When hot metal is poured in there is a great deal of pressure trying to force the two halves of the mold apart. This bench will require 8 molds weighing about 1600 lbs.
