Artificial stone is just now receiylng attention from scientists and the world at large, and every new idea or theory is eagerly sought after. As the result of a series of experimente, it is anQounced that the stone made from lime and quartzose sand is likely to take rank at the head of these artificial producĂ­s. This compound, which is 12% per cent of lime and 87% per cent quartzose, is ground, sifted and mixed, and then subjected to a very heavy pressure. One peculiarity of the process is the use of holling water for mixing the ingredients, which drives out air-bubbles and open seams in the stone. It has been demonstrated that stone made in this way will, after a few weeks' expcsure to the atmosphere, resist a pressure of 4,0C0 pounds to the square inch. It is a well-understood fact that modern methods of making mortar, piaster and artificial stone have been undergoing a complete revolution. Boiling water is used in laying cement, and every effort is made to maintain a temperature that will cause rapid evaporation and absorption.
