Classification by consumption method
Signal or ornamental fireworks are classified into launch fireworks (launch fireworks, launch fireworks) and in-process fireworks (in-process fireworks) depending on the consumption method..
Launch Fireworks (Fireworks)
It is a firework that launches a paper ball "ball" (smoke fireball) filled with "stars" that is formed by forming explosive powder into a spherical shape. Place a propellant powder on the bottom of a cylinder facing upwards and place a ball on it to prepare for launch. For launching, a fire type called "throwing" is thrown in from the ejection port above the cylinder and the propellant is ignited. At the same time as the launchfuseThe flame ignites, and the ball rises to a predetermined height, the squib breaks, reaches the powder charge inside the ball, the ball ruptures, and the star ignites and scatters. The amount of propellant and the length of the squib are adjusted and selected according to the size of the ball (height of fireworks). There are various types of stars, such as those that burn while catching the tail of light, those that burst while falling, and those that change color after the ball ruptures. It is important to pack the stars uniformly inside the ball, but the detailed technique is a secret of the fireworks master.
Fireworks that are artificially designed, such as using multiple fireworks.
- Star mine (rapid fire)
- Fireballs, stars, whistles, etc. are arranged in order, connected by rapid fire lines, and launched at high speed one after another. Sometimes used as a backing at the end of a framing. Balls from No. 2 (about 6 cm) to No. 4 (about 14 cm) are mainly used. To control thesecomputerAnd electronicrelayThose that frequently use are sometimes called "Digital Star Mine".
- Frame work
- Rope tackle(Niagara)
- A flame tube connected by a fast-fire wire is hung in a line from several to several tens of meters, and sparks simultaneously flow down from the flame tube by ignition. Some of the fireworks festivals have a length of 2000 m.Niagara Falls.
- Underwater device
- A device that emits and ejects stars and sparks from a cylinder.. What is ejected while holding or holding is called a "hand cylinder".
- Car fireworks
- A cylinder filled with gunpowder is placed around a disk, etc., and the disk is rotated by the propelling force of the gunpowder to eject the sparks in a circular shape.

Classification by structural performance
Signal or ornamental fireworks are classified into fireworks (fireworks) and fireworks other than fireballs depending on the structure and performance..
Most of the launch fireworks have light that spreads concentrically at the time of launch, and the shape of the ball itself is also spherical.On the other hand, the early fireworks did not become circular even when they were launched, and the shape of the fireworks themselves was often cylindrical.Compared to spherical fireworks, cylindrical fireworks can increase the amount of gunpowder and produce gorgeous light and color, but it is said that it is difficult to change the color during bursting.In the past, Japanese fireworks spread concentrically, but it was difficult to manufacture, and it is said that it was a secret only to some samurai fireworks.MeijiIt is said that the XNUMXth generation Yabei Kagiya acquired the technology during the period and many circular fireworks have been produced since then.
Traditionally, the size of the “ball” of launch fireworks isSize,ShakuIt is represented by. From a 6.06 inch ball (No. 2 ball) with a diameter of about 60.6 cm to a shaku ball (No. 20 ball) with a diameter of about 30 cm, and a XNUMX shaku ball (No. XNUMX ball),Four shakudamaThere is (No. 40 ball). The diameter of the two shaku balls is about 500 m, and the diameter of the four shaku balls, which is said to be the largest in the world, extends to about 800 m. However, this number is the thickness of the launching cylinder (inside), and the actual diameter of the fireworks ball is slightly smaller than this. Specifically, the diameter of No. 20 ball is about 60 cm instead of 57 cm. Also recently[When?]The world's smallest fireworks that were developed have a ball diameter of 1 cm and a launch distance of 2 m. However, it has not been put to practical use because it is still in the development stage.
"Itte Q to the end of the world!], a fireworks ball (four shaku three-dimensional large thousand rings) whose diameter at the time of flowering is estimated to be 1 km was made and fried. However, the fireworks ball itself was too heavy and did not rise, so it exploded in water and failed.
Fireworks (fireworks) are classified as cracked and warm.

Above all, the starschrysanthemum"Chrysanthemums" are those that have tails that spread like flowers, and those that do not.peonyIt is called "button thing" by analogy with. Moreover, what spreads in a double spherical shape is called a "core".
- Deformation of splitSaturnA thing in which stars scatter in the shape of is called a "shaped object".
- In the airKusutamaA part that breaks up and pops out.
- What is commonly known as "noshiro" and "sign fireworks". It is used to signal the holding of various events such as athletic meet. The "three-step thunder" that sounds three times in a row and the "five-step thunder" that sounds five times are mainly used.
- Bags, hangings, etc.
- Daytime fireworks where dolls made of thin paper such as Japanese paper in a bag shape, smoke balls and flags hanging on a parachute fall slowly. Launch is prohibited except under specific conditions. "Bagmono" was patented by fireworks master Jinta Hirayama in the United States in 1883, but this is the first Japanese patent in the United States..
There are the following points to appreciate "warimono" which is a typical fireworks display.
- Are the balls firmly seated? The fact that the ball is open at the point where it rises is said to be "the seat of the ball is solid." This is an important point to spread cleanly.
- Is the tray removed? Does the star look like a tray in a perfect circle?
- Do you have all the vanishing points? The colors of the stars have changed all at once and have disappeared all at once. However, there are some fireworks that intentionally shift their mouths.
- Are the stars spread evenly and missing teeth?
- Is the color of the stars good, and is there a clear color? In addition, how to color the stars is an important point to show the individuality of the fireworks artist.
Fireballs are also used for in-process fireworks such as Star Mine.
Fireworks other than fireballs

However, around this time, mass production of gunpowder was started due to the demand for guns, and it seems that Japanese fireworks were also manufactured.
As a record that "fireworks viewing" was held from the Warring States period to the early Edo period,Date MasamuneOf the castleYonezawa Castleso,1589/8/17(Tensho 17th year7/7)At night, I saw the fireworks by "The Great Chinese" ("Sadayama Koujiya record", "Date Tensho Nikki", etc.),1613/In 8 monthTokugawa Ieyasu Sunpu CastleAt the British EmbassyJohn SarisWhen I had an audience, I was told that the accompanying Merchant merchant showed me a firework in the shape of sparks coming out of a cylinder (“Sumpu Government Minutes』"Miyanaka Hakusaku" "Butoku Henen Shusei"), etc. (However, Masamune's article is based on the compilation material around the time of Genroku, and it has been pointed out that it is very similar to Ieyasu's article..
In the Edo era, when the war broke out, a gunpowder store specializing in fireworks appeared. The birthplace of Tokugawa,(I.e.Centered onMikawa district TheEdo Period,Tokugawa ShogunateWas the only officially licensed manufacturer to manufacture and store explosives. With such a history, fireworks have spread and developed in the Mikawa region centered around Okazaki for a long time, and the name of Mikawa fireworks has been desired throughout the country. As a remnant, the smoke and fire manufacturing industries and wholesalers are still concentrated in the Mikawa and Enshu districts nationwide.
1648/ToShogunate Sumida RiverFireworks have been banned from other countries, and fireworks are said to have been popular since that time. It is thought that toys at that time were toy fireworks.1712/Published around the timeJapanese and Chinese three-year-old drawing society』(Ryoan TerashimaAuthor, illustration of the Edo periodEncyclopedia), rat fireworks, wolf smoke fireworksAre introduced.
KeianThe first year (1648),KanbunFireworks bans were issued in 5 years (1665) and Kanbun 10 years (1670),EdoInside, the fireworks were stopped at all and gradually moved to the region. It is said that the launch accident occurred and the ban was issued repeatedly.
The first locksmith, YaheiYamatoShinohara (Yoshino-gun,laterNaraGojo CityIt is said that he was born and was good at making fireworks since childhood. In 1659, Yabei, who came out in Edo, sold a toy firework with a reed inside. After that, Yabei continued research and set up a shop in Yokoyama Town, Ryogoku, and began to inherit the generation as "Kakaya" for generations, continuing to the present age (2018th generation as of 15)... After that, research on large fireworks,1717/The fireworks are launched at the water god festival.
Incidentally,Sumida River open fireworksAs the origin of the, there are the following widely disseminated discourses.
1733/,KinaiAroundfamineSuffered from and in EdocholeraIn a gloomy world in which a large number of dead were killedYoshimunePrayed for the memorial service for the dead and for the evil spirits to disperse, and held a water god festival in the rivers of both countries (the Sumida River), and around 20 fireworks were displayed at the festival..
However, this episode was created gradually from the mid-Meiji era to the early Showa era, and is far from historical facts.. For example,choleraThe first epidemic in Japan occurred in Western Japan in 1822 (Bunsei 5).It's against the fact that it was fashioned in the 1730s.. Detail is,Sumida River fireworks displaySee section.
Along with the locksmith, the representative of Edo fireworksTamayaIs. Kiyoyoshi, who was the XNUMXth generation locksmith,1810/ToGoodwillAfter that, the name was changed to Ichibei and a store was opened in Yoshikawa, Hirokoji, Ryogoku..
In Edo, where the two major fireworks masters of locksmiths and Tamaya came to enter, the river opening of both countries wasRyogoku BridgeTamaya is in charge of the upstream, and locksmith is in charge of the downstream... The voices of "Tammaya" and "Kaguya" were created.[Note 4]..

Calling)Mad songOr "Tamaya is nice and locksmith is good"SenryuIt is considered that the popularity of Tamaya surpassed the locksmiths because of the fact that there are still some. However1843/5/16(Tempo14/4/17), there was a fire from Tamaya, and there was a tumult that not only the shops but also the townscape of about half a town (about 1500 tsubo) was baked... At that time, a misfire was determined to be a felony, and by coincidenceGeneralKeikei OfToshoguSince it was the night before the departure of worship, strict disposal was given and TamayaPlace(Property confiscation), Ichibei is EdoReady(Exiled), and the family name was cut off in just one generation.
At the time, fireworks specialist fireworks such as locksmiths were called townsman fireworks. other than this,DamingThey ordered the gunpowder craftsmen under their control to compete and set fireworks at the Sumida River.

Modern Japanese fireworks technology incorporates this difference in direction.

LocksmithSecond World WarDuring the period, Tadō Amano, thirteenth generation, stopped producing fireworks, and as of 2013, he has become a full-fledged landing company.
Regarding fireworks, there are many records especially in Edo, but it does not mean that fireworks were not produced in other regions. Especially there was trade with foreign countriesKyusyuWhen,Nagano,AichiFor example, fireworks have been made since the Edo period. Especially,MikawaguniOkazaki region (Aichi prefecture岡 崎 市The neighborhood) is the birthplace of Tokugawa Ieyasu, and regulations on gunpowder are lenient, and since the Edo period, the townspeople have competed to manufacture fireworks. It is said that this is a remnant of many toy fireworks wholesalers around Okazaki as of 2013. The other major fireworks producing areas in Japan are Nagano prefecture,Niigata,Akita,IbarakiAnd there are many regions in the Tokugawa family that are related to the Tokugawa family.
After the Meiji era
In the 18th and 19th centuries in Europe, new compounds were synthesized by the development of chemistry, and "Western fireworks" made from them were used as raw materials.MeijiNew Year (1868/) Was first imported to Japan.
From the overseas in the Meiji eraPotassium chlorate,aluminum,magnesium,Strontium carbonate,Barium nitrateMany chemicals were imported, and not only new colors were added to the fireworks that were expressed only by the strength of the orange color called charcoal color until then, but the brightness also changed significantly... The start of importing these substances1879/から1887/The shape of fireworks in Japan has changed drastically since then. Fireworks made with earlier technologyJapanese fire, After thisYanghuoSometimes you can say that.
Vivid fireworks with various colors were created by new chemicals, but it was during the Meiji era that serious accidents occurred due to lack of knowledge about chemicals. In particular, potassium chlorate becomes unstable when mixed with other acidic chemicals, and has the property of increasing the risk of explosion even with a slight impact. If this happens, it will result in a serious accident.
As a record of a large-scale launch of a Western fire with various colors,1889/2/11 OfImperial Japanese ConstitutionAt the celebration event of the promulgation,Imperial Palace OfDouble bridgeIt was fried from the ground.
Until then, fireworks manufacturing had no licenses or regulations for landing,1910/It became a permission system. Local fireworks before this wereFarmerMany of them were manufactured as hobbies, but after that, it became necessary to make full use of chemical knowledge, so that the pyrotechnicians would become specialized.
TaishoDuring the period, metal powders such as magnesium and aluminum were introduced as luminescent agents, and it became possible to bloom large flowers brightly in the night sky. In addition to potassium chlorateCapstoneMixedRed explosionThe fireworks with great pronunciation effect were completed. It was during the Taisho era that the famous fireworks masters such as Miya appeared..
It is a firework that has developed technology steadily in this way,ShowaTo enter the,Sino-Japanese warIn a world situation in which the war is expanding, it will reach a stagnation period. Fireworks production is expensive instead of being bannedExcise taxHowever, at the beginning, fireworks for send-off soldiers sent off,GhostThere were fireworks at the memorial service and prayers for the victory such as the memorial service fireworks. However, due to the expansion of the war, the fireworks display at the Sumida River opens1937/Was canceled. Meanwhile, fireworks manufacturers have smoke tubes and incendiary tubes (IncendiaryWas reproduced).

At this time, the amount of landing permission was only 600, but there were 70 spectators in the large flowers of the peaceful period ("Ryogokugawa Opening Yearbook").
After the defeat, many Japanese fireworks, including toy fireworks, were exported overseas, but as of 2013,ChugokuThe amount of imports from China is larger, and exports are decreasing sharply. As of 2013, many fireworks companies are small and medium-sized enterprises with local roots, and have adopted a hereditary system that transfers technology from parents to children.
Fireworks and culture

Environmental pollution by fireworks
Fireworks重金属Residue, sulfur compounds,Particulate matter, Soot containing other low concentrations of toxic substances.. The by-products of these combustions differ greatly depending on the way the raw materials are mixed. (For example,bariumMay add green to fireworks by adding salt.. These substances also include those that are toxic. )
Also fireworksPerchlorateHas been said to be a source of. United States Environmental Protection AgencyRichard Wilkin et al. conducted a study on the use of fireworks above waters, keeping in mind the effects of environmental perchlorate on humans and wildlife. Sources of perchlorates range from lightning and certain fertilizers to those found in rocket fuels and explosives. Scientists have long suspected that local fireworks festivals could be another source of emissions, but little research has been done. Wilkin's research group established that fireworks were one of the causes of perchlorate pollution by analyzing the water in a lake in Oklahoma before and after the fireworks festival in 2004, 2005 and 2006. .. Within 14 hours of the fireworks display, the concentration of perchlorate increased from 24 times background background to 1,028 times. After 24 hours, the concentration reached its maximum, and after 20 to 80 days, it had reached the level before the competition..
Perchlorate is a type of solid salt that easily dissolves and moves in groundwater and surface water. When perchlorate is mixed in drinking waterthyroid OfIodineIs known to be inhibited.. Although there are currently no federal standards for drinking water across the country, some states have already established public health goals and action levels, and some states are trying to establish maximum limits. For example, the US Environmental Protection Agency is studying the effects of perchlorate on the environment as well as drinking water. .. AlsoCaliforniaIssued guidelines on the use of perchlorate.
Pollutants from fireworks raise concerns about health risks. The effects of long-term exposure to low levels of poisons from many sources on the majority of people are unclear. On the other handAsthmaFor patients and those with multiple chemical hypersensitivity, smoke from fireworks can exacerbate the disease.
The United States of America
MassachusettsSeveral states, including the United States, have legislated drinking water standards for perchlorate. The California Legislature enacted the Perchlorate Pollution Control Act (AB 2003) in 826. The law called on the California Toxic Substances Control Agency (DTSC) to adopt regulations that set forth the best controls for perchlorates and substances containing perchlorates. This control method was adopted on 2005 December 12 and came into effect on 31 July 2006 .. California also established drinking water standards in 2007. Arizona,Maryland,ネ バ ダ 州,New mexico,New York State,TexasSeveral states, including the United States, have established non-mandatory recommendation standards.
The judiciary has also ruled on perchlorate contamination. For example, in 2003, the US District Court for the State of California found that perchlorate was a flammable and "characteristically" hazardous waste.Decided to apply.
Some U.S. companies claim to work with Chinese manufacturers to reduce and ultimately eliminate pollutant perchlorate..

FireworksACCIDENTCan be roughly divided into accidents during the manufacturing process at the fireworks factory and accidents during the demonstration at the fireworks display. The accident at the fireworks display is not only the danger of fireworks,Crowd accidentVarious preventive measures have been taken in advance by the management side in order to prevent accidents that may occur due to the large number of spectators gathering, but it has not yet been prevented. Also, fireworks held at home do not fully recognize the danger of explosives.ChildrenIs the main body of play, so do careless handling and playfully perform dangerous actions such as pointing to people, animals, or objects.This tends to lead to accidents. There is also a risk of fire due to the mistreatment of fire after playing.
When you fireworks at home, in a park, etc.,bucketMake sure that you can extinguish the fire at any time, such as by drawing water, and then extinguish the fireworks after they have burned out properly with water, and confirm that the fire has been sufficiently extinguished. Also, since there are no adult managers, such as only small children, avoid fireworks. Unfired fireworks (especially those for launch fireworks are called "black balls") have the risk of reignition or explosion, and they need to be dipped in water.
There have been many fireworks accidents in the past, but the statistics remainthe 1950sIt's about time. From the 1950sthe 1960sThere were many explosions at the fireworks factory, and there were times when more than 10 people were killed each year. Many said that the fireworks factories would explode and kill employees, but some of them caused damage to nearby buildings and the lives of the general public, and these accidents gradually tightened regulations on fireworks production. However, some claim that using a safe type of explosives and keeping the amount stored should have prevented most of these accidents.
