Mealed powder 1 4 Saltpetre 6 0 Sulphur 1 8 All dry compositions must be well mixed; first by the hands, and then passed several times through fine hair sieves, that the ingredients may be thoroughly incorporated. In mixing compositions which require fire, the greatest precautions are necessary; particularly in those where gunpowder enters. The dry parts of the composition may in general be mixed together first, and put by degrees into the cauldron, while the other ingredients are fluid, being well stirred all the time of putting in. When the dry ingredients are inflammable, the cauldron must not only be taken off the fire, but the bottom must be dipt in water, to prevent the possibility of accidents while mixing them. R. LAB.
