This was an abrasive carborundum wheel, and when it revolved at 4,000 revolutions per minute it was apt to break into pieces and scatter around.
Carborundum sawn marble is a further stage in the production of worked marble and is not covered by the open general licence.
There are plenty of engineering gentlemen who know the difficulty of putting a steel handle on to a piece of carborundum, and they will bear me out.
If you take the case of a handle, say, for a carborundum sharpener, it is a very difficult thing to put a handle on to a carborundum tool for sharpening.
I tell him advisedly that a carborundum sharpener is not included and is not dutiable, and therefore the handle for a carborundum sharpener will not be dutiable.
Substances such as carborundum, acrylic texture mediums, sandpapers, bubble wrap, string, cut card, leaves and grass can all be used in creating the collagraph plate.
Acheson, in 1890, originally attempted to synthesize artificial diamond, but ended up creating blue crystals of silicon carbide, which he called "carborundum".
