Buffing and Polishing Materials - Ganoksin Jewelry Making Community

Aluminum oxide "A" is 0.3 micron in size and Aluminum "B" is an extremely small micron size of 0.05. To put this into perspective, 50,000 grit is .5 micron and 100,000 grit is .25 micron. When we purchase a bar of red, white or green rouge we have no idea of the amount of oxide used or the size of the particle used in manufacturing the bar.
