Fireworks -- Early works to 1800
To make a flaming star, you must first have made a circular piece of
strong wood, about one inch thick and two feet diameter; round this
block fix eight points, two feet six inches in length each; four of
these points must be straight, and four flaming; these points being
joined on very strong and even with the surface of the block, nail tin
or paste board on their edges, from the block to the end of each,
where they must be joined; this tin must project in front eight
inches, and be joined where they meet at the block; round the front of
the block fix four pieces of thick iron wire, eight inches in length
each, equally distant from each other; this being done, cut a piece of
paste board round two feet diameter, and draw on it a star, as may be
seen in fig. 52. This star cut out, and on the back of it paste oiled
paper, then paint each point half red, and half yellow, lengthwise;
but the body of the star must be left open, wherein must run a
brilliant wheel, which is made as follows: Have a light block turned
nine inches long; at each end of it, fix six spokes, at the end of
each spoke put a two ounce case of brilliant fire; the length of these
cases must be in proportion to the wheel, and the diameter of the
wheel when the cases are on must be a little less than the diameter of
the body of the small star; the cases on the spokes in front must have
their mouths incline outwards, and them on the inside spokes must be
placed so as to form a vertical circle of fire. When you place your
leaders, carry the first pipe from the tail of one of the cases in
front to the mouth of one of the inside cases, and from the tail of
that to another in front, and so on to all the cases; your wheel being
made, put it on a spindle, exactly in the center of the star; this
spindle must have a shoulder at bottom, to keep the wheel at a little
distance from the block. This wheel must be kept on the spindle by a
nut at the end; having fixed on the wheel, fasten the transparent star
to the four pieces of wire; then when you fire the wheel, you will
first see nothing more than a common horizontal wheel; but when the
first case is burnt out, it will fire one of the vertical cases, which
will shew the transparent star, and fill the large flames and points
with fire; then it will again appear like a common wheel, and so on
for twelve changes.
Of Touch Paper for Capping of Serpents, Crackers, &c.
Dissolve, in some spirits of wine or vinegar, a little salt petre,
then take some purple or blue paper, and wet it with the above liquor,
and when dry it will be fit for use; when you paste this paper, on any
of your works, take care that the paste does not touch that part which
is to burn. The method of using this paper is by cutting it into
slips, long enough to go once round the mouth of a serpent, cracker,
&c. When you paste on these slips, leave a little above the mouth of
the case not pasted; then prime the case with meal powder, and twist
the paper to a point.
