White Aluminum Oxide 25 Micron
White aluminum oxide is an abrasive used during the fine grinding stage of making a telescope mirror. Please enter the number of units next to each size of packaged powder you would like. Then click "Add to Cart."
All of our abrasive grains and powders come in sealed jars. This keeps them safe from contamination during shipping and later when you are using them. We recommend that you use only one abrasive at a time to lower the risk of scratching your mirror, however, we have labeled both the jar and lid to make sure each pair is kept together.
