Plate I

The scene represents the interior of a shop in which several workers in this profession are busy with different operations.

Figure 1. The furnace covered by a chimney pipe.

Figure 2. Worker busy operating the bellows to animate the wood coal fire that surrounds the crucible. Near him we see two molds pressed one against the other above a brazier to dry them.
