How Marble is Extracted | This Old House

Richard Trethewey travels to the world’s largest underground quarry where the stone originates to find out how marble makes it from inside a mountain to a kitchen. #ThisOldHouse #AskTOH SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse Richard Trethewey goes to Southern Vermont to a marble quarry where stones have been used for many monuments in Washington, D.C. such as the Jefferson Memorial and the Arlington National cemetery. Going almost a mile inside the cave by truck, Richard meets the lead man Keith Millard and they watch how machines with long blades tunnel thorough the mountain cutting gigantic marble blocks cut out of the walls. They watch as a water bag cushion expands to allow a 150-ton marble block to fall free. Over at the finishing plant, the blocks are cut into smaller blocks. General Manager Luca Mannolini shows Richard how he looks for imperfections in a block before it gets cut into slabs. They watch as a machine cuts 40 slabs at a time out of one block. The slabs then have to be finished—polished, honed, or brushed.
