Loose Aluminum Oxide Powder

Description

Aluminum Oxide Powder is a perfect tool for lapping sharpening stones. Choose one of 5 available grit: F 230, F 400, F 600, F 800 and F 1200.

How to use

Warning! Respirator required to work with F800 and F1200 aluminum oxide powder. Inhalation can cause illness.

The Aluminum Oxide powder should always be coarser than a sharpening stone.

Take a slate pencil and put crosshatch pattern to the surface of the stone. Never skip this step. Your goal is to get rid of crosshatch completely. If you notice left-over of pattern somewhere, it means geometry is not flat yet.

Always add water to make a suspension, not dry Aluminum Oxide. Try to use glass area evenly. Your glass will wear over time because Aluminum Oxide affects glass too.

When Aluminum Oxide disintegrates, put another pinch (refresh). If there is too much suspension, clean your glass. Use a straight edge or metal ruler to check flatness. If you are not sure, make crosshatch pattern again.

The abrasive hygiene should be a priority. Don't let single coarse particle to remain in fine lapping.
