Firecracker Encyclopedia
An A–Z, India-specific encyclopedia of firecracker types, trade terms and regional names — schema-marked so every definition is machine-readable.
Firecracker Encyclopedia
Anar, chakri, wala, net rate: the terms on a Sivakasi price list rarely match what's printed on the box in plain English. This firecracker encyclopedia decodes them entry by entry: India-specific trade jargon, regional names and regulatory terms, defined in plain language and sourced to PESO, CSIR-NEERI, the Supreme Court and the NGT.
The short answer:
- This encyclopedia defines the real catalogue terms used in the Indian crackers trade: aerial types (sky shot, aerial repeater), ground types (chakkar, flower pot), sound crackers (atom bomb, bijili, garland), sparklers/novelties, and the trade and regulatory words that appear on every box and price list.
- Regional names (anar, chakri, phuljhadi, lar) are the same products under a different, commonly used name rather than a separate category.
- Regulatory terms (PESO, CSIR-NEERI, green cracker, 125 dB limit) explain who certifies a cracker and what limit it must sit under before it can legally be sold.
- Each entry below is a self-contained definition; deeper entity pages on units, certification marks, regulators and regional names sit one click away.

Aerial crackers
A tube launch and an overhead burst are what separate this category from ground and handheld types.
Sky shot: a single-tube aerial firework that launches once from its base tube and bursts into a colour-and-crackle display at altitude. The simplest aerial format; multi-shot versions (12, 25, 30, 60, 120 or 240 shots) fire the same effect repeatedly from one cake before burning out. See the sky shots range.
Aerial repeater / "shots" cake: a box of linked launch tubes (a "cake") that fires its aerial shells one after another on a single fuse, commonly sold by shot count: 12-shot, 25-shot, 30-shot, 60-shot, 120-shot and 240-shot are the standard Sivakasi counts. Each shot is one aerial burst; a "60 shots" box means 60 successive bursts from that one item, not 60 separate crackers.
Rocket: a stick-mounted or tube-launched firework that flies up under its own thrust and bursts at or near the top of its flight, usually with a whistle, colour tail or crackling report. Sold individually or in multi-pack sets. See the rockets range.
Garland cracker / "wala" string: see Sound crackers below; garlands are ground-fired but often grouped with aerial and sound catalogues because they share the "linked series" mechanic.
Ground crackers
Being lit and left in place, rather than launched or held, is what puts these crackers in their own category.
Flower pot / anar: a small cardboard or clay pot that, once lit, throws a steady cone of coloured sparks upward for several seconds without leaving the ground. "Anar" (Hindi/Urdu for pomegranate) is the common trade name for the same product, referencing the fountain-of-seeds shape of the spark cone. Sizes run from small ("chhoti anar") to koti (heavy-fill, taller cone). See the flower pots range.
Ground chakkar / chakri: a flat, coiled firework that spins rapidly on the ground once lit, throwing sparks outward in a circular pattern while it rotates. "Chakri" (from chakra, wheel) is the everyday name; "ground chakkar" is the catalogue name for the same item. See the ground chakkar range.
Fountain: a broader ground-fired category producing an upward or outward spray of coloured sparks for an extended duration, taller and often longer-burning than a standard flower pot. See the fountains range.
Sound crackers
A loud report is the entire point of this category, with little or no light effect built in.
Atom bomb: a high-charge, single-report ground cracker built purely for one very loud, sharp bang, with no colour or light effect. One of the loudest single-unit formats in the standard catalogue. See the sound crackers range.
Bijili: a small, single-report cracker, typically red paper-cased, that gives one sharp crack and is sold loose or in strip counts rather than individually. "Bijili" (lightning) is the trade name across most Sivakasi price lists; red bijili and stone bijili are common variants. See the one-sound crackers range.
Sutli bomb: a small, thread-fused (sutli means cotton thread/twine) report cracker, functionally similar to a bijili but named for its twine-style fuse rather than an electric one; a common vernacular term for compact single-bang crackers.
Garland cracker / "wala" string / lar: a length of small crackers joined by a continuous fuse so that lighting one end fires the entire string end to end without a pause. Sold by count: 100 wala, 1000 wala, 2000 wala and up to 10,000 wala are standard pack sizes; "lar" or "maala" are the same product sold by length rather than a fixed count. Because a garland packs many reports into one continuous burst, its permitted per-unit noise ceiling is lower than a standalone cracker's. See the 125 dB limit below and the garland crackers range.
Sparklers & novelties
Sparkler / phuljhadi
a thin wire or bamboo stick coated in a pyrotechnic composition that, once lit, burns down slowly while throwing a steady shower of small sparks, held at arm's length rather than placed on the ground. "Phuljhadi" is the common Hindi/Urdu name for the same product. Sold in lengths from 10cm to 50cm and in electric (plain), colour, gold and crackling variants. See the sparklers range.
Twinkling star / matches
a small, low-intensity novelty cracker that produces a brief shower of light sparks, marketed at younger or first-time users as a gentler alternative to a full sparkler. See the twinkling star matches range.
Fancy novelty
a catch-all catalogue term for crackers built around a visual or gimmick effect (spinning tops, ground novelties, combination light-and-sound items) rather than a single loud report or aerial burst. See the fancy novelties range.
Gift box / combo pack
a pre-assembled box mixing several product types (sparklers, flower pots, a few sound crackers, a small aerial item) sold as one unit for gifting or first-time buyers rather than a single product type. See the gift boxes range.
Trade terms
Shot / shot count
one aerial burst from a repeater cake. A "60 shots" or "100 shots" product name states the number of individual aerial bursts that one item fires before it's spent. It is not a count of separate crackers in the box.
Wala
the Hindi trade suffix meaning "of [count]," used on garland packaging to state how many linked crackers are in the string: 100 wala, 1000 wala, 10,000 wala. See fireworks units & measures explained for the full breakdown of shot, wala, bundle and net rate together.
Net rate
the manufacturer's base wholesale price for a product before retail margin, discount and GST are added; the figure Sivakasi price lists are built around. It is not the price a buyer pays at checkout.
Gross weight vs. actual/net count
gross weight is the shipped weight of a box including packaging; actual or net count is the number of usable pieces inside it. Listings that state only gross weight without a piece count are the common source of buyer confusion on bulk garland and bijili packs.
Regulatory terms
PESO
the Petroleum and Explosives Safety Organisation, the central government body that licenses fireworks manufacturers and tests/certifies formulations, including noise output and chemical composition, before a product can legally be manufactured or sold in India.
CSIR-NEERI
the Council of Scientific and Industrial Research's National Environmental Engineering Research Institute, the body that developed the green cracker formulations and certifies which products may carry the green CSIR-NEERI logo and QR code. Full comparison of the SWAS, STAR and SAFAL formulations it certifies: green cracker certification marks.
Green cracker
a firecracker certified by CSIR-NEERI to cut particulate matter by at least 30% (or 20% PM plus a further 10% gaseous-emission cut) versus a conventional cracker of the same type, while leaving out barium nitrate, mercury and arsenic. A green cracker still bangs, sparks and flashes like its conventional counterpart. The reduction is in emissions, not in effect. See the green crackers range.
125 dB limit
the Supreme Court's national noise ceiling. No firecracker sold in India may exceed 125 dB(AI) or 145 dB(C) pk, measured 4 metres from the point of bursting (Writ Petition (Civil) No. 728 of 2015, order dated 23 October 2018). For joined products such as a garland, the permitted ceiling drops by 5 log₁₀(N) dB, where N is the number of crackers in the string, so a 100-wala garland is held to 115 dB(AI), a tighter ceiling than the flat 125 dB(AI) baseline that applies to a single standalone cracker.
