British Dynamite

Potassium" Dynamites (Dynamite a La Potasse). A series of expls proposed in 1873 by the British Dynamite Co, Ltd (which later became the Nobel Explosives Co, Ltd), which consisted of NG 15, saltpeter 70—75, plus paraffin and powdered charcoal 7-17%. Another mixt contained NG 18, saltpeter 71, charcoal 10, and paraffin 1%... 

The starting point of the present British commercial explosives industry was the formation of the British Dynamite Company in 1871 by Alfred Nobel and a group of Glasgow business men. Ardeer factory in Ayrshire...

According to Nauckhoff and Bergstrom [7] a nitrator with mechanical stirring was used as long ago as the 1870 s in 1872 in the British Dynamite Co. in Ardeer and in 1879 by A. Liedbeck at Isleton in Switzerland, Paulilles in France and Avi-gliana in Italy. 

Soda Dynamites. Dynamites contg Na nitrate as the chief ingredient. The first formulations of this type were prepd in 1873 by the British Dynamite Co Ltd later to become Nobel s Explosives Co, Ltd). They contained 70—75% Na nitrate, about 15% NG and 7-17% paraffin and charcoal dust. Due to the high hygroscopi-city of Na nitrate, these expls were rejected by the Brit military authorities... 

Wettersicbere Dynamite (gelatinous and nongelatinous) are those safe to use against firedamp and coal dust. They correspond to Amer "permissible" or British "permitted" Dynamites... 

Ume (plum bossom) dynamite derived from British Saxonite Matsu (pine tree) dynamite, a kind of blasting gelatine Ran (orchid flower), derived from Carbonite-and Kaede (maple leaf), a modification of Belgian Grisoutite. The last two were-soon withdrawn from use due to their undesirable products of explosion. The composition of the above explosives is tabulated below (Table 132) (according to Yamamoto [85]). 

Ume dynamite which was improved by adding a considerable quantity of borax thus making it similar to the British Samsonite. 

Shoan dynamite (Shoan is the abbreviation of Shosan-ammonia, i.e. ammonium nitrate). Shoan dynamite is semi-gelatinous and resembles British Dynobel.

Following tests are described in Ref 1, pp 25—7 a)Centrifuge Test b)Porty Degree Test and c)British Test. Of these the centrifuge test waa adopted by the Bur Mines as being best suited for ascertaining the liability of dynamites to exude... 

Initially nitrostarch could not be used in practice due to its inadequate chemical stability, but by the beginning of the present century nitrostarch had found practical application in the U.S.A., where it was introduced by a British chemist, Hugh [24] who in 1900 and 1903 constructed and set in operation two nitrostarch factories one near Asburg Park, New Jersey, and the other near Wharton. Hugh advertized non-freezing Hugh s Powder as a substitute for dynamite. It has been proved to be pure nitrostarch. 

Blastine, A safety expl consisting of a mixt of NH4Cl04,NaN03,DNT 5% paraffin wax(Ref 1). It was claimed by Kedesdy to be 50% more powerful than dynamite. According to Barnett (Ref 3) this is a Swedish expl, but Stettbacher(Ref 4) and Thorpe (Ref 5) report a British expl called Blastine which consists of NH4CI04 60, NaNOj...
