Pumice

Pumice is a natural polishing media ideal for metals treatments. Due to the particular physical structure pumice has a smooth but effective abrasive action suitable for copper treatments. The microscopic action of the pumice particles creates a surface ideal for maximum adhesion of coatings in aluminium extrusions. This unique mineral leaves surfaces smooth and shiny.

Pumice is highly recommended for surface finishing prior to etching and engraving. Ideal for silver polishing and copper.

Glass Beads

Chemically inert, non magnetic, non-inflammable and non-explosive. They may be used to remove surface contaminants prior to treatment. Glass Beads enable surfaces to be cleaned, textured, decorated without damage to the base material.

Applications include metals (i.e. stainless steel ,aluminium) polishing.
