In The Heat Of The Foundry, Steinway Piano ‘Hearts’ Are Made : NPR: “Hensley and Houseman guide the ladle, suspended from a system of overhead beams, out to the foundry floor, where the plate molds are lined up. The molds are made of chemically treated sand, which hardens quickly around a form that is then removed, leaving a hollow space inside. The ladle hovers over each mold in turn and tilts. A stream appears and descends into a hole left in the sand. The iron is more than 2,000 degrees Fahrenheit and incandescent, a luminous yellow-orange.”
