United States began using slag in their amber produc- tion, limiting the quantities to approximately 5 per cent of the batch weight, excluding cullet. This limit, was made necessary by high iron content of the slag and excessive variation of oxides. The sheet glass factory of Oxelosund, Sweden, has used slag since 1935.

The Devolution of Declining Industries

plants such as alumina refining (see Ghemawat and Nalebuff [1985]), firms usually shrink continuously as demand declines (soda ash, rayon, baby foods, vacuum tubes, cigars, and electric coffee percolators are some of the many examples: see Harrigan [1980]). We study competition under the opposite of all-or-nothing adjust-

Metallurgical Coal

2015-10-6 · Metallurgical coal – also known as coking coal, is a key ingredient for the produc-tion of steel by creating the coke necessary during the reduction process of making iron and steel. Coke is a porous, hard black rock of concentrated carbon that is created by heating bituminous coal without air to extremely high temperatures.
