Roman candles shells

Consumer Fireworks. An assortment of small fireworks devices are permitted for use by private citizens in many areas in the United States and elsewhere throughout the wodd. These devices consist of items such as wire sparklers, fountains, Roman candles, sky rockets, mines, and small aerial shells. 

Figure 4.4 shows shell stars bursting above fans of Roman candles. 

Burning stars, such as those originating from Roman candles or shells (Figure 8.5), emit radiation in the ultra-violet, the visible, near-infrared and mid-infrared regions of the electromagnetic spectrum, as displayed in Figure 8.6. 

Succeeding chapters describe the manufacture and functioning of the most popular hreworks, including rockets, shells, fountains, roman candles, bangers, gerbs and wheels in what is hoped is a stimulating and easily assimilated way for those approaching the subject for the hrst time. 

BOMBETTE A Combination of candles and/or shells packed in a box and fired by interconnecting fuse or a mini shell found as a component of a Roman candle, mine or shell. 

STAR A compressed pellet of explosive composition designed to be projected as a pyrotechnic unit, with visual effects. Used in mines, shells, rockets and Roman candles. 

Stars which contain aluminum are known as electric stars because of the dazzling brilliancy of their light, which resembles that of an electric arc. Stars which contain chlorate and sulfur or antimony sulfide or arsenic sulfide or picric acid are dangerous to mix, likely to explode if subjected to too sudden shock, and unsafe for use in shells. They are used in rockets and Roman candles. Perchlorate compositions, and chlorate compositions without sulfur, sulfides, and picric acid, will tolerate considerable shock and are used in aerial bombshells. 

Hub up the mixture thoroughly In a mortar with just enough boiled oil to make it cohere, and pump it into Homan candle stars the oil will preserve the steel from rusting. For Roman candles or Italian streamers they will be ready at any time for rockets and shells they may bo matched and enveloped, like figure 32. a day or two previously. They form beautiful stars. Or they may be charged in cases, and primed with chlorate meal powder. Or they may be damped with lao solution. 

No. 11. Tailed, Streamer, or Comet Stars, far Rockets, Shells and Roman Candles. 

The G>nch Shell con Cs of a 10 diameter shell packed with three ball roman candles mads specially for this purpose. TKs cases of the candles are made of very Strong paper so that they can be thin and no empty portion is left at top and bottom. In addition to the little roman candles, colored Stars are added. This makes a very effective shell. 

The burning speed of a star is very important and will vary according to the purpose for which it is used. An exhibition roman candle, for example, will need a much fiercer composition than a shell star, because a roman candle star is projected through the air at quite a speed and the flame is sometimes extinguished. 

The fireworks that operators refer to as candles or Romans originated in Rome at the time of the Renaissance in the 14th century. Every person in the audience is familiar with these fireworks that eject a succession of stars, mini-shells and hummers into the sky, the projectiles reaching greater heights with every shot while the fireworks send great columns of sparks skywards between those shots.
