LTS: Juragua Iron Company Mine Photographs

The Juragua Iron Company was the first American company to become interested in iron mining in Cuba. The mines were located in the province of Santiago at the eastern end of Cuba. The Santiago province climate is hot, but not affected by fevers or malaria. The company first went to Cuba in the early 1880s to begin iron ore mining.

Vitrified Clay Pipe Operations & Maintenance Handbook

vitrified Clay Pipe (CP) is a rigid pipe manufactured from clays and v shales. The weathering forces of nature allow the soluble and reactive minerals to leach from rock and soil over time, leaving an inert material. These chemically inert, raw materials are transformed into a dense, hard, homogeneous clay pipe by firing in kilns at temperatures of
