Searching the globe for interesting fireworks information turns up a not so well known manufacturing giant, outside of China! The area around Sivakasi, in the Southern part of India is home to as many as 1,000 fireworks factories and is responsible for up to 90% of India's fireworks production including both professional display, and consumer fireworks.
India's culture celebrates many religious festivals with fireworks, and it is becoming increasingly difficult for them to meet their own demands, they are it seems though, one of the few countries who manufactures more fireworks than they import.
Fireworks here are largely created using ancient methods, although the industry didn't really take off until the 1920's it thrives and is taking steps toward mechanizing the processes for safety and production purposes, hopefully making them a contender in the global market in the near future.
Similar to China, firecrackers are a mainstay item in India, and one of the local favorites is called the Jute Twine Bomb, a very loud firecracker that is also used for agriculture and scaring birds away from airport runways.
The yearly average temperature of around 89 degrees, and the mainly dry climate makes it an excellent area for production, although the low humidity can also create some safety concerns.
India produced fireworks are known for high quality construction and raw materials, which are becoming increasingly difficult to find supply of and largely control market pricing. Who knows when fireworks produced in India might be available in your area!
