🌳 Seemai Karuvelam Tree (Prosopis Juliflora)
Locally called Seemai Karuvelam in Tamil Nadu, this tree is considered invasive but is highly useful for fireworks and charcoal production.
Its wood is dense and rich in carbon, which makes it ideal for making charcoal — a key ingredient in firework chemicals.
🔥 Step 1: Charcoal Production
Wood from the Seemai Karuvelam tree is cut and dried.
The dried wood is burnt in a low-oxygen environment (in kilns or pits).
This process (called pyrolysis) removes moisture and volatile compounds, leaving behind pure carbon (charcoal).
The charcoal is lightweight, porous, and highly flammable, which makes it perfect for firework formulations.
⚗️ Step 2: Powdering & Mixing
The charcoal is ground into a fine powder.
It is mixed with other key chemicals:
Sulfur (S): Helps ignition and smooth burning.
Potassium Nitrate (KNO₃): Works as an oxidizer, supplying oxygen for combustion.
Together, this forms the basic gunpowder (black powder) mixture:
75% Potassium Nitrate + 15% Charcoal + 10% Sulfur
🎆 Step 3: Firework Chemical Applications
Atom Bomb Crackers & Sound Crackers → Charcoal adds explosive strength.
Color Fireworks → Charcoal acts as a base fuel with metal salts for colors.
Fountains & Sparklers → Mixed with metal powders for sparks.
