A method of making an explosive in the form of an emulsion, which includes two stages being a first stage comprising directing a plurality of 0.5 to 5 mm diameter jets of the discontinuous phase into the continuous phase, in the presence of an emulsifier, and feeding the continuous phase containing the discontinuous phase through a static mixer to form a relatively coarse, fuel-rich emulsion; and a second stage comprising directing a plurality of 0.5 to 5 mm diameter jets of the discontinuous phase into the continuous phase of said coarse emulsion, and feeding the coarse emulsion with the added discontinuous phase through two further static mixers arranged in series. The invention further extends to an apparatus for performing the method of the invention.
