6.22 Commodity shops

Commodities are refined from raw materials that are produced by the common residents of townes. There are seven types of raw materials: crop, livestock, ore, rock, water, fish, and lumber.

HELP TOWNE PRODUCTION explains how materials are produced and obtained. 

Commodities are refined from materials and other commodities at a refinery. The refining process does not happen automatically - instead, a citizen with the Trade privilege can use the command REFINE <1-100> <commodity> to consume the raw materials and create the desired commodities. These commodities are then added to the city stocks (HELP TRADE).

You can use the command REFINE CHECK <commodity> to see the materials and gold required to produce one piece of the commodity. The gold is taken from the Trade ministry coffers.
