Ebonite

The addition of about fifty per cent. changes the rubber to a hard black substance known as "ebonite," or "hard rubber." ❋ Unknown (1895)

I may mention as a curious thing that these ravenous animals, that devoured everything they came across, even to the ebonite points of our ski-sticks, never made any attempt to break into the provision cases. ❋ Unknown (2009)

One way that they can be produced is as follows: A sharp-pointed needle is placed perpendicular to a non-conducting plate, such as of resin, ebonite, or glass, with its point very near to or in contact with the plate, and a high voltage Leyden jar a type of capacitor or a static electricity generator is discharged into the needle. ❋ Unknown (2007)

The platinoid wire is insulated and the covering of silk that insulates it is wound on the ebonite bobbins just where my finger is. ❋ Unknown (2003)

Some of the older anti-Byronists were able to fool with their parameters in systematic ways that would show up on the ebonite meters under the Swiss mountain: there were even a few self-immolations, hoping to draw the hit men down. ❋ Pynchon, Thomas (1978)

Corresponding to the jaw is a built-up section, almost a facial codpiece, of iron and ebonite, perhaps housing a radio unit, thrusting forward in black fatality. ❋ Pynchon, Thomas (1978)

Black chairs with the East German equivalent of PVC upholstery and chrome legs, an ebonite console on one wall with some of the panels illuminated. ❋ Hall, Adam (1968)

There were conspiratorial glances in his direction, because he had the expression he adopted on big days: his set look, his pipe at an angle, squeezed so tightly between his teeth that he had been known to snap the ebonite tip. ❋ Simenon, Georges, 1903- (1965)

After cleaning the pumice off by means of water and a rag, the final touch may be given by means of vaseline, applied on cloth or on ebonite shavings. ❋ Richard Threlfall (N/A)

In boring ebonite the drill should be withdrawn from the hole pretty often and well lubricated, for if the borings jam, as they are apt to do, the heat developed is very great and the temper of the drill gets spoiled. ❋ Richard Threlfall (N/A)

This is on account of the fact that ebonite sometimes springs a little out of shape when the skin is removed. ❋ Richard Threlfall (N/A)

The system of ebonite ring, coil, and pins is then fastened into the gun-metal coil carrier, which is cut away entirely, except near the edges, where it carries the pin brackets C. ❋ Richard Threlfall (N/A)

The advantage of using a polished ebonite surface is that such a surface deteriorates more slowly under the influence of light and air than a surface left rough from the tool. ❋ Richard Threlfall (N/A)

In front of the other opening of the tube is a horizontal fork of ebonite, whose arms carry on the side opposite the tube a metallic ball. ❋ Various (N/A)

The ebonite ring A is bored with four radial holes, through which are slipped from the inside the fused quartz bolt-headed pins B. ❋ Richard Threlfall (N/A)

It is easy to make large tubes out of sheet ebonite by taking advantage of the softening which ebonite undergoes in boiling water. ❋ Richard Threlfall (N/A)

It is advisable to expose ebonite to the light as little as possible, especially if the surface is unpolished, for under the combined action of light and air the sulphur at the surface of the ebonite rapidly oxidises, and the ebonite becomes covered with a thin but highly conducting layer of sulphurous or sulphuric acid or their compounds. ❋ Richard Threlfall (N/A)

At ordinary temperatures ebonite is hard and brittle and breaks with a well-marked conchoidal fracture. ❋ Richard Threlfall (N/A)

Those damn ebonites moved into our [area]., now [we can't] [sell] our house. ❋ Preved (2006)
