Method of Making Concrete Tombstones.
Patent for a method of making concrete tombstones which are waterproof and don't require wetting during the drying process to prevent cracking, reducing the drying time from 30 days in the shade to 4 days in the sun. This is achieved by adding salt to hold water which prevents cracking while drying, and a paint coat of aluminum powder and gasolene to waterproof the concrete and add a shine to it.
