A Piece of Our Industrial Past
Our foundry pieces look great, but they seem even better when you dig deeper and get some history on them...
"Wood craftsmen begin by making a model of the desired metal object from hardwood, using lathes, and planes, which were all powered by the Knight Wheels. The model, called a pattern, is then placed in a casting flask, in its simplest form a topless and bottomless box split in half around its perimeter. The flask is placed on a board and a sand mixture (containing seacoal, bentonite, clay, and pitch) poured and rammed around the pattern. The additives harden and stabilize the sand so that the flask can be split apart and the pattern removed leaving an exact impression or mold in the sand. The pattern can be reused almost indefinitely to create more molds in additional casting flasks. A channel or gate is left in the sand so that when the flask is rejoined, the ironworkers can pour the molten iron into it through the opening. When the iron has solidified the flask is broken apart, destroying the sand mold in the process, to reveal the rough casting."

These wood molds make great statement pieces for any room and are unique conversation starters.
