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.
Grind with emery or Carborundum, as described under a previous head.
Carborundum, or silicide of carbon, is largely superseding emery and diamond dust as an abradant.
The detector D is of the Carborundum crystal or electrolytic pattern.
Of all the bodies tried there were two which withstood best—diamond and Carborundum.
For this, a very little fine flour of emery or Carborundum is the best and quickest.
