It is practically the same as [Steelite].
*S.K., S.R., S.S., S.V. were partially gelatinised fibrous smokeless powders, introduced by the Smokeless Powder Co. about 1889. They are no longer made. The following analyses were given in “Arms and Explosives,” 1917, p. 77—
| S.R. | S.S. | |
| Nitrocellulose, insoluble | 45·2 | 53·0 |
| ” soluble | 25·5 | 13·0 |
| Metallic nitrates. | 18·5 | 18·0 |
| Nitro-compound | — | 10·0 |
| Vaseline | — | 4·6 |
| Starch | 8·0 | — |
| Moisture | 2·8 | 1·4 |
The nitrocellulose was made from lignin. S.S. was a 38-grain bulk powder; S.R. was a fibrous powder for rifles; S.K. a similar powder for small rifles, and S.V. for revolvers.
*SMOKELESS DIAMOND is a 33-grain bulk smokeless powder for shot-guns, introduced in 1903 by Curtis’s and Harvey. According to an analysis in “Arms and Explosives,” 1917, p. 78, its composition is—
| Nitrocellulose, insoluble | 69·0 |
| ” soluble | 6·6 |
| Metallic nitrates | 15·0 |
| Vaseline | 2·5 |
| Charcoal | 5·6 |
| Moisture | 1·3 |
*SOLENITE.—A smokeless powder introduced in Italy in 1896 for use in rifles—
| Nitroglycerine | 34 |
| Nitrocotton, soluble | 63 |
| Mineral jelly | 3 |
It is gelatinised with the aid of acetone, and is made in the form of translucent short tubes of a light brown colour.
