Porcelain balls are utilized to achieve bright finishes without the use of steel media. Because of its shape, it imparts a single point of contact resulting in a very fine finish to almost any area it can reach. Porcelain balls will not leave impingement marks that steel media produces on some softer metals and/or flat surfaces. Their lighter weight lessens the distortion potential for lighter work and wire forms. Very popular for delicate parts, fine edge blanking and precious metal burnishing.
