A COMPLETE
SYSTEM OF PYROTECHNY;
OR THE
ART OF MAKING FIRE-WORKS.
In the art of making fire-works, great attention must be paid to the
well-mixing of the materials--without which all labour is thrown away;
to the purity of the articles; and to the proper quantities of each.
Sulphur, to be good, must be of a high colour, and crack and bounce
when held in the hand. For small fire-works, such as may be bought in
the flour will be found quite good enough, but for the larger kinds,
the lump brimstone ground is preferable.
