7. Property of material being, abraded (brittle material can be rapidly abraded whereas ductile / malleable metal like gold will flow instead of being removed).
VIII. TYPES OF ABRASIVES I.
According to Craig : The abrasives used can be classified as :
A. Finishing Abrasives These are hard, coarse abrasives used initially to develop desired contours and remove off gross irregularities. B. Polishing Abrasives These are smaller particle size and are less hard than abrasives used for finishing. They are used for smoothening surfaces that are roughened by finishing abrasives. C. Cleaning Abrasives These are soft abrasives with small particle size and are intended to remove softer materials that adhere to enamel or a restoration. These dental abrasives could be employed in the form of three basic designs as mentioned previously.
