21. Seasoning Stone

Seasoning Stone. In order to evaporate the quarry water, which most limestones and sandstones contain when freshly quarried, they should be exposed to the air for a considerable time before being used, as this seasoning makes the stone harder, and more durable under the action of frost. It is supposed that the quarry water contains in solution considerable cementing material, which is deposited when the water evaporates, firmly binding together the particles. It can readily be seen that such kinds of stone should have all necessary cutting, or carving, on them done as soon as possible after quarrying.
