Achieve bright finishes without the use of steel media

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 other 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.

Because of their light weight and relatively low hardness, you will have slightly longer cycle times that steel shot. Porcelain balls will also need to be "broken in" before use. For best results, cycle the media by itself (but with burnishing liquid) until a glaze forms on the surface of the media. Please note that a break-in period of 4 to 6 hours is required.
