There are several methods of producing a smooth or glossy surface on clock parts made from metal, glass, stone, plastic, wood, etc. Almost all the metal parts in a clock movement can be polished; parts such as pallets, pinions and pivots are polished to reduce friction on their working surfaces, allowing the parts to slide easily together and reduce the possibility of injurious material clinging to them. Other clock parts such as brass weights, pendulum bobs, bezels, frets and finials are polished for the sake of appearance. Metal surfaces are polished with a polisher of soft steel, iron, bell metal, tin, zinc, lead or wood according to circumstances. In all cases the polisher is softer than the surface being polished, and is charged with compounds ranging from carborundum and oilstone dust to rouge and diamantine.
