Final Polish Accessories - Polyester Pads, Felt Wheels, Cerium Oxide

Polyester Felt Pads

Used on optical glass for some time, these polishing pads are relatively new to architectural glass. They are faster than wool felt for two reasons. They polish at a higher speed than wool, and they hold more cerium oxide per application.

The material is .150" thick (slightly over 1/8") and is mounted on a flexible backing. A pressure-sensitive adhesive is applied to the backing. When the pad is worn, peel it off the mounting disc and replace with a new one.

The polyester fiber will operate at twice the speed of wool without overheating the glass, and it has a much longer life than the same thickness of wool.

These pads can also be used with a pumice slurry for prepolish. This technique is used by Steuben Glass at Corning. They come without a mounting hole. Any special diameter can be ordered.

Wool Felt Wheels

These pads are made of the finest wool felt available and their quality is extremely consistent. They are a medium hardness.

A cerium oxide slurry is applied manually to the wheel. The center hole is 1". Other diameters and hole sizes can be ordered.

24" x 3"	250

Cerium Oxide

GLASTAR PREMIUM - This is a polishing compound with a very high percentage of cerium oxide. Despite its cost, it will be less expensive in the long run than conventional cerium compounds because of its high concentration of cerium oxide. It is particularly well suited for hand beveling. It is tan in color.
