Glasweld Polishing Cork is Useful for applying Pit Polish and as a safe alternative to heat, Polishing Corks are always ready to save the day. The abrasive grain is contained in an elastomer bond and sized for grinding and polishing and a high concentration of cork particles are used as a filler. … Resilient bonds together with the cork particles give a mild polishing action and a bright finish of superb quality.
Cork is a natural polishing material. Glasweld polishing corks are ideal when used to polish cured pit fill resin.
In the glass industry, cork has long been recognized for its polishing qualities and when used with Glasweld’ 30400 Premium Pit Polish, cork produces just enough friction to warm the surface of the cured pit resin to produce a high gloss finish with minimal effort. Shape, size, and insignia on corks purchased from Delta Kits may vary but will not affect usability.
