Emery, Carborundum and alundum wheels are developed from the grindstone of the distant past.
The Carborundum brick was selected on account of its hardness.
Carborundum or crystolon is also made up into refractory ware for high temperature work.
This detector consists simply of a crystal of Carborundum supported between two brass points.
The sponge becomes saturated with water because of the capillary action of the Carborundum upon the water.
The detector D is of the Carborundum crystal or electrolytic pattern.
Carborundum, or silicide of carbon, is largely superseding emery and diamond dust as an abradant.
Grind with emery or Carborundum, as described under a previous head.
Of all the bodies tried there were two which withstood best—diamond and Carborundum.
The flesh side is finished by fluffing it on the emery or Carborundum wheel (Fig. 33).
