that is basic, or not siliceous, is used, and additions of basic material are made to the molten charge during treatment. Opposed to acid process, above. Called also Thomas process.

The process of washing molten pig iron by adding iron oxide, proposed by I. Lowthian Bell of England about 1875.

hat the latter contains, through the agency of a blast of air which is forced through the molten metal; -- so called from Sir Henry Bessemer, an English engineer, the inventor of the process.

impressions, or of shaping metal or plaster in a mold; the act or the process of pouring molten metal into a mold.

iron mold or portion of a mold, serving to cool rapidly, and so to harden, the surface of molten iron brought in contact with it. Raymond.

A pot, bucket, or basin, in which molten plate glass is carried from the melting pot to the casting table.

ocess of devitrifying, or the state of being devitrified. Specifically, the conversion of molten glassy matter into a stony mass by slow cooling, the result being the formation of crystallites, microbites, etc., in the glassy base, which are then called devitrification products.

luminium is added to lower the melting point, usually in a petroleum furnace, keeping the molten metal at the bubbling point until it becomes quiet, and then pouring the molten metal into a mold lined with a special mixture consisting essentially of molasses and ground burnt fire clay; also, a casting made by this proc…
