marble polish

The first polish involved using an iron plate to rub a sharp sand across the stone, thus removing the irregularities of the surface. The second used a finer sand, or sometimes dust from a whetstone, and the third used rottenstone, an abrasive red limestone powder known as tripoli. The final polish was performed with a putty made from tin oxide. So burnished, the marble would be as smooth as glass (King, 2000). (King, 2000)
