CAST STONE vs. NATURAL LIMESTONE
When comparing manmade cast stone products to quarried stone, three factors need to be taken into consideration: Time, Cost and Durability. When making cut stone parts with intricate design work, such as a Corinthian capital, the same amount of time is involved in reproducing each individual part. When using cast stone, once the original design work is complete on the first stone produced, the time is dramatically reduced on all following cast stones produced. Because of the speed and ease of producing additional pieces, the cost is substantially lower as well. Cast stone is more durable than natural limestone due to the process by which it is produced. By hand-forging each part, casted stone gains strength and durability without the air pockets that are common in natural stone. 21 Topics for projects and presentations: 1.
