Generally, the strings (sometimes containing as many as several thousand crackers) would be hung from an overhead line before ignition. Individual Mandarin crackers were most often braided into 'strings' of varying lengths, which, when ignited, exploded in rapid sequence. Mandarin crackers produced a dimmer, less brilliant flash when they exploded also. Mandarin crackers produced a less loud, duller thud compared to modern flash-light crackers (which utilize a different explosive known as flashвЂ…powder). Sales, packaging and brandingДЄ firecracker roll containing 10,000 firecrackers.Д®arly (pre-1920s) Chinese firecrackers (also known as 'Mandarin firecrackers') were typically 1вЃ„ 2 to 2 inches (13 to 51В mm) long, and approximately 1вЃ„ 4 inch (6.4В mm) in diameter, and were charged with blackвЂ…powder. However, green crackers still contain harmful pollutants such as aluminium, barium, potassium nitrate and carbon. Green or environment friendly firecrackerДЄfter India's NationalвЂ…GreenвЂ…Tribunal (NGT) enacted a ban on the sale and use of crackers on Diwali festival in 2020, the CouncilвЂ…forвЂ…ScientificвЂ…andвЂ…IndustrialвЂ…Research (CSIR) developed green crackers made from cleaner raw materials which reduce emissions by suppressing the production of dust their emissions are 30% lower but are also are of reduced loudness at 110-125 decibels instead of the more than 160 decibels of traditional firecrackers. 200 to 300 firecrackers were tied up in a bunch, then red clay was spread at the bottom of the bunch and forced into each end of the firecracker with a punch gunpowder was poured in, then the other end was sealed with an awl by turning the tube inward, and a fuse inserted. The firecracker tubes were made from pieces of straw paper wrapped around iron rods of various diameters and then tightened with a special tool. The bamboo paper was cut into strips of 14 inches (360В mm) long and 1вЃ„ 3 inch (8.5В mm) wide, laid on a table a string of gunpowder was placed at the center with a hollow tube, then twisted up to make a piece of fuse. At that time, firecrackers were made by women and children workers, using straw paper to make the body of the firecracker, while the fuse was made of paper imported from Japan made from the inner lining of the bamboo plant, or rice paper, stiffened with buckwheat paste. JamesвЂ…DyerвЂ…Ball, in his book Things Chinese, has a detailed description about the process and material used for making firecrackers at the end of the 19th century.
