The whole to be of such character and consistency as not to be liable to liquefaction or exudation.

DYNAMITE No. 1.—Consisting of not more than 75 parts by weight of thoroughly purified nitro-glycerine, uniformly mixed with 25 parts by weight of—

(a.) An infusorial earth known as “kieselguhr,” or
(b.) A non-explosive mixture of kieselguhr with such other ingredients and in such proportions as may for the time being be sanctioned by the Governor in Council, e.g. :

Carbonate of sodium .. 8 parts (or less) by weight in substitution for an equal amount by weight of kieselguhr.
Sulphate of barium ..
Mica ..
Talc ..
Ochre ..

Provided—
(1.) That the said (a) kieselguhr or (b) non-explosive mixture shall be sufficiently absorbent in quality when mixed in the above proportions to prevent exudation of nitro-glycerine; and
(2.) That there may be added to the kieselguhr or non-explosive mixture an amount of carbonate of ammonium not exceeding 2 parts by weight in every 100 parts by weight of the finished dynamite.
