Steel manufacture, chemicals This category includes the chemical substances which are manufactured as part of steel and alloy steels. The following list identifies those elements which may exist in steel or which may comprise compounds present in steel or alloy steels. Aluminum, beryllium, boron, calcium, carbon, cerium, chromium, cobalt, copper, hafnium, iron, lanthanum, lead, magnesium, manganese, molybdenum, nickel, niobium, nitrogen, oxygen, phosphorus, selenium, silicon, sulfur, tantalum, tin, titanium, tungsten, vanadium, yttrium, zinc, zirconium.

Glass, nonoxide, chemicals This category encompasses the various chemical substances manufactured in the production of non-oxide inorganic glasses. For purposes of this category, 'glass' is defined as an amorphous, inorganic, usually opaque substance consisting of a mixture of elements formed by fusion into a mass that cools to a rigid condition without crystallization. This category consists of the various chemical substances, other than by-products or impurities, which are formed in melting furnaces during the production of various glasses and concurrently incorporated into a glass mixture. Any glass contains one or more of these substances, but few, if any, contain all of them. The elements listed below are normally present as elements but may also be present as halides, sulfides, selenides, or in more complex substances. Trace amounts of oxides or other chemical compounds may be present. Aluminum, Antimony, Arsenic, Bismuth, Cadmium, Gallium, Germanium, Selenium, Silicon, Sulfur, Tellurium, Zinc.
