Book excerpt: Excerpt from Physical and Chemical Tests on the Commercial Marbles of the United States In order to determine whether repeated heatings to tempera tures which do not affect the chemical composition of the marble cause any weakening or disintegration, a set of cubes was prepared from a white calcite marble. Eleven of these were tested in the original state, and 18 were repeatedly heated in the electric oven to 150° C. After 50 heatings to this temperature 9 were tested ln compression in the same 'manner' as the original cubes. The remaining 9 cubes were heated to this temperature 100 times and then tested.
