'''Cheddite''' is a class of [[explosive material]]s invented in 1897 by E. A. G. Street of the firm of Berges, Corbin et Cie and originally manufactured in the town of Chedde in [[Haute-Savoie]], [[France]], in the early twentieth century.<ref>{{cite book|last=Marshall|first=Arthur|title=Explosives:Their Manufacture, Properties, Tests and History|publisher=P.

Closely related to [[Sprengel explosive]]s, cheddites consisted of a high proportion of [[inorganic]] [[chlorate]]s mixed with nitroaromatics (e.g. [[nitrobenzene]] or [[dinitrotoluene]]) plus a little paraffin or [[castor oil]] as a moderant for the chlorate. Several different types were made, and they were principally used in [[quarry]]ing. Due to availability of ingredients and easy production process it was also the most common explosive material manufactured by the [[Polish Underground State]] in occupied [[Poland]] during [[World War II]]; it was used for production of the [[R wz. 42]] and [[Filipinka]] hand grenades. 

Since the 1970s, Cheddite is the commercial name for primers CX series (CX 50, CX 1000 and CX 2000) for [[shotgun]] cartridges.
