This created a sudden demand for spiegeleisen.

A similar material is a pig iron with high content of manganese, is called spiegeleisen.

Ferromanganese, also known as spiegeleisen, is an alloy.

Granules and powders, of pig iron, spiegeleisen, iron or steel.

Realising the enormous value of his discovery he continued with his experiments to master the facts concerning spiegeleisen when alloyed in various ways.

This removed the phosphorus impurities as slag, produced by chemical reaction with the liner, and no longer required spiegeleisen.

Mushet carried out experiments on the sample, based on those he had previously carried out with spiegeleisen.

Powders (of pig iron, spiegeleisen, iron or steel) are also classified under heading code 7205.

Pyrolusite is extensively used for the manufacture of spiegeleisen and ferromanganese and of various alloys such as manganese-bronze.

In order to give the steel the desired properties, other substances could be added to the molten steel when conversion was complete, such as spiegeleisen (a ferromanganese alloy).

His method was to first burn off, as far as possible, all the impurities and carbon, then reintroduce carbon and manganese by adding an exact amount of spiegeleisen.

This prevents the loss of carbon from the molten steel (so called blocking the heat); ferromanganese, spiegeleisen, silicides of calcium, and many other materials are used for the same purpose.

Meanwhile, William F. Durfee (engineer and architect), Robert Mushet, Thomas Clare and John Brown were brought in by Ward to make the procedure necessary to produce Bessemer steel, especially using spiegeleisen.

He was unsuccessful at this but did observe several European steelmakers and managed to get the rights to Englishman Robert Mushet's patent use of spiegeleisen (manganese-rich pig iron) for better overall quality of steel produced this way.

The process of separating zinc from ore was discovered by the company in 1848 and led to zinc mining, the discovery of zinc oxide and the production of spiegeleisen, an alloy made from zinc oxide, used to reinforce iron and steel.

Having an understanding of production processes can also be very helpful in classification, for example knowing that spiegeleisen is generally obtained from ores and therefore classified under the same heading as pig iron - rather than a ferro-alloy as it's often referred to in the trade.

(g) Remelting scrap ingots of iron or steel Products roughly cast in the form of ingots without feeder-heads or hot tops, or of pigs, having obvious surface faults and not complying with the chemical composition of pig iron, spiegeleisen or ferro-alloys.

To produce high quality steel from a high-phosphorus ore, Mushet realised that he could operate the Bessemer converter for longer, burning off all the steel's impurities including the unwanted phosphorus and the essential carbon, but then re-adding carbon, with manganese, in the form of a previously obscure ferromanganese ore with no phosphorus, spiegeleisen.

Spiegeleisen is sometimes also referred to as specular pig iron, Spiegel iron, just Spiegel, or Bisalloy.
