Small round water jacket furnace for silver-lead ore . A water jacket furnace could be used to reduce non-ferrous oxide ores mixed with coke, to produce metal, but its main use was smelting the more common sulphide ores. The feedstock was the ore, coke and fluxes. When smelting lead sulphide ores, a water jacket furnace produces molten lead and ...
A water-based primer, used primarily on wood. A primer (/ ˈ p r aɪ m ər /) or undercoat is a preparatory coating put on materials before painting.Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted.
Experimental archaeometallurgy is a subset of experimental archaeology that specifically involves past metallurgical processes most commonly involving the replication of copper and iron objects as well as testing the methodology behind the production of ancient metals and metal objects.
Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...
In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining the final material is chemically identical to the raw material. Refining thus increases the purity of the raw material ...
Ferrous metallurgy is the metallurgy of iron and its alloys. The earliest surviving prehistoric iron artifacts, from the 4th millennium BC in Egypt , [ 1 ] were made from meteoritic iron-nickel . [ 2 ]
