Gesteins-PLASTAMMON.—A German blasting explosive containing not less than 70 per cent. of ammonium nitrate, glycerine, not more than 15 per cent. of nitro-toluene or other nitro-compounds, and not more than 4 per cent. of nitro-semicellulose.
Steinkohlen-PLASTAMMON is a variation of this, containing not more than 25 per cent. of potassium nitrate, and intended for use in coal mines.
*PLASTOMENIT was an early German shot-gun powder which possessed no great merits. The following was the composition of a sample examined in 1893, and given in “Arms and Explosives,” 1917, p. 90—
| Nitrocellulose, insoluble | 32·7 |
| ” soluble | 19·3 |
| Metallic nitrates | 21·0 |
| Dinitro-toluene (solvent) | 26·0 |
| Moisture | 1·0 |
PLASTROTYL.—A German high explosive for filling shell. It consists of a partially liquid mixture of trinitro- and dinitro-toluene gelatinised by means of not more than 0·5 per cent. of collodion cotton, and mixed with a small quantity of turpentine or soft resin. It does not appear to be in use now.
PLESSIT is a blasting explosive that was introduced in Germany during the War. It consists of potassium chlorate, not more than 9·5 per cent. of kerosene and 0·5 per cent. of albumen. Wetter-Plessit III. contains sodium chloride as well.
