Cerium Oxide Polishing Powder has different colors that vary with the content of praseodymium in the raw material and the temperature. The polishing powder is more brownish-red when the praseodymium content is higher. For pure Cerium Oxide polishing powder, the color is white with a little red at a high roasting temperature and light yellow at a low roasting temperature.
