By 1843, perhaps earlier, Hiram Weed's kiln in White Hollow was in operation. Like the earlier model in the Valley this was an intermittent type kiln, one requiring the fire to die out and cool before the removal of the calcined lime. When the process was completed the calcined lime, also called burnt lime, was raked out and barreled.
