By the 1940s endless uses for calcium products extracted from marble deposits became obvious. Calcium was needed for agricultural, pharmaceutical and paint products. Alabama Marble Company had already moved in this direction, having introduced its first Raymond Mill products for animal feed, insecticides, and joint cement materials in 1933. By-products were sold under the name of Alabama Calcium Products. By 1964, the company had completed one of the largest multi-product calcium carbonate plants in the United States, and in 1967 it closed its structural marble plant.
