How is Wrought Iron Made? - History of Steel - Carolina ...

Producing iron by this method is rather inefficient. The yield from the best ore rarely exceeds 50% of the iron found in the ore. Ordinarily the yield is on the order of 20% and the remaining iron is lost in the slag. Iron ores range in composition, depending on where it is mined from around the world.

Antique Slag Glass Lamps | Collectors Weekly

Slag glass, also known as marble glass or malachite glass, is a type of opaque, streaked pressed glass.Production of slag glass originated in late-19th-century England, where glass manufacturers are thought to have added slag from iron-smelting works to molten glass to create a range of effects—from tortoiseshell to marbling.

Wrought iron - Wikipedia

Wrought iron is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling wood that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosion-resistant and easily welded.

Iron and Steel Slag Statistics and Information

In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and iron are formed.
