Turpin s expls were soon superseded by Cheddites (see Vol 2, C155-L to C164-R), introduced by Street in 1897 Refs 1) Commission des Substances Explosives, MP 11, 53-56 (1901) 2) Daniel (1902),... 

The above Shekhter equation is not applicable to expl mixts such. as Cheddites, Guhr-dynamite and some AN expls. Here deton vel increases with density until it reaches a certain maximum and then it. gradually decreases. The max shifts towards higher density with the increase in diam of chge. For example, for chge diam of Cheddite 20 mm, the max velocity (ca 25 50) is reached at density ca 1.12, while chge diam of 40mm, the max (ca... 

Potassium Chlorate, supposed to be discovered by Glauber in the 17th century (middle) was prepd by C.L. Bertollet in pure state and its props detd. He proposed using it in lieu of K nitrate in BkPdr, but abandoned the idea after disastrous expln during its manuf in 1788, which killed several persons. The first successful mixts using K chlorate were Cheddites (See Vol 2 of Encycl, p C155ff and Marshall 1 (Ref 11, pp 35—36)...

In the book of Belgrano (Ref 31, pp 355—60) are described chlorate and perchlorate Cheddites Accdg to Ref 28, p 321, Cheddites are too sensitive to mechanical action to be used as bursting charges in shells, but they can be used for loading land mines (See also Cremonite, Esplosivo 86/14, Esplosivo P, Esplosivo S, Manlianite, Polvere cannel and Romite)...
