The illuminant in fireworks is called a "star". Perhaps the name came from the fact that the illuminating light resembles a real star in the sky. There are two configurations of the star with tail (s, r, 1, k) dnd with no tail (a f, m q, g->i, j). Smoke(t z) always has a tail and is called a "smoke star". In pictures a star with a tail is expressed by a line with no tail by a point. The trajectory of a star with a tail is denoted by a straight line or curved line (Fig.l). a is an image of a fast star and b a slow star. The slow star is curved by the force of gravity.

Smoke Dragon A smoke star with a parachute. 

Fig.76 shows a smoke star which is hung by a parachute. The composition is packed with a piece of thin paper (Japanese Gampi) and rolled into an eddy-cylinder(Fig.77) Then it is pressed into a paper container. This process was produced to make the work cleaner. Two or three smoke holes are bored in it with an awl from i he outside.

Another type of willow smoke star which gives large streamers of colour is manufactured by loading one of above compositions into a small cardboard shell 2-3 cm in diameter(Fig.78) or in a kraft-paper tube of...

The black dragon composition is pressed into a tin tube and primed with a small igniting star and a piece of black match. The black willow is used in the form of cut stars The anthracene is somewhat expensive, and half the quantity can be replaced by naphthalene v/ith the same effect. There are three requirements for black smoke stars producing pretty smoke no remaining fire and safety in manufacturing and handling. 

When the fuse is ignited, the propellant is ignited after a short time projecting the stars in opposite directions. Small flowers(described later), thunders, smoke stars etc. are often used in place of stars. 

This is in principle a combination of a daylight and a night shell. This is a kind of Poka containing a flare of high intensity and smoke stars of realgar composition. The smoke streams look white rather than yellow at night when they are illuminated by the flare(s.5) ...
