Excerpt from A Glossary of the Mining and Mineral Industry The glossary also includes many terms relating to ceramics and the clay industry, glass making, foundry practice, railway and build ing construction, electrical installation and power-plant equipment, and chemical terms relating to metallurgical practice. Complete lists of terms for'each of these allied industries are beyond the scope of this glossary. Paleontological terms, although closely associated with geology, are far removed from mining and metallurgical opera tions, and for this reason have been omitted.
