Molten Molding Casts

Summary:
The Molten Molding Casts are a Dwarf invention, mostly applied to large-scale products---most notably, Iron and Molten Golems. It stems from a running stream of molten metal, which drains into the mold itself.

Practical Applications:
With this method of construction, less metal is required to form the desired product and having an expert sculptor "carve" the various shapes out of block of the desired material. This allows rapid and consistent production, yet the molds must be cleaned and smoothened regularly---so as not to allow impurities from the last to enter the next or allow the product to become misshapen.

To disastrous effect, the Dark Iron of Emperor Dagran Thaurissan sent such Golem production into overdrive. By placing the foundry by the mouth of a magma chamber, a constant flow of material could drain into a canal---which would be blocked or redirected by use of a stone block attached to a lever, pulled by strong men. One may be able to use an engine to more precisely and quickly move the levers.
