This content explains how the pumice stone is applied to the paper with a brush along with the varnish soon after it is simply used up and turned into a powder. While the term sandpaper is still used, most abrasives reported today are made of silicon oxide or silicon carbonate. Quartz sand can also be used to polish wood.
