Pumice powder is highly recommended for surface finishing and scratch removal prior to etching and engraving.
Due to the particular physical structure pumice has a smooth but effective abrasive action. The brittle and chemically inert nature of the material is unique. Pumice is a natural polishing media which is ideal for a variety glass treatments (i.e. TV screen polishing, toughned and flat glass, crystal polishing, aerospace windscreens).

Alumaglass
Alumaglass is a new abrasive offering advantages when compared to other traditional abrasive media. It enables considerable time saving in most applications.It is ideal for glass etching and engraving. Alumaglass has a lower hardness than fused alumina. This produces a superior finish creating a smooth, polished surface.
Suitable for all types of glass applications.
