The process of removing moisture from the blast of an iron blast furnace by reducing its temperature so far that it will not remain suspended as vapour in the blast current, but will be deposited as snow in the cooling apparatus. The resultant uniformly dehydrated blast effects great economy in fuel consumption, and promotes regularity of furnace operation, and certainty of furnace control.

The process of washing molten pig iron by adding iron oxide.

A process for preserving timber and making it incombustible by impregnating it successively with solutions of iron sulfate and calcium chloride in vacuo.
