Removing the glaze from a sharpening stone

A sharpening stone consists of abrasive grit particles bonded together into a cohesive structure. As the stone is used the grit dulls and is slowly washed away to expose new grit. Without enough water or oil used as a medium to float this old grit and steel particles away a glaze of old grit and steel particles can become imbedded in the surface of the stone and effectively stop the grinding action. This glaze can be removed by lapping the stone on a flat diamond stone or on 150 to 220-grit wet-and-dry sandpaper backed by glass or some other hard flat surface. Remove the glaze and the performance of the stone will be greatly improved.
