Potassium Chlorate KClO₃

Premium Potassium Chlorate (KClO₃) – The Classic, High-Energy Oxidizer for Bright Colors, Fast Burns & Legendary Pyrotechnics

Command explosive brilliance and razor-sharp performance with high-purity Potassium Chlorate – the historic powerhouse oxidizer that's fueled fireworks innovation for centuries, delivering fast-burning, high-luminance flames, vivid colors, and unmatched reactivity in stars, salutes, and specialty effects.

This fine, bright white crystalline powder (99%+ pure, low-impurity grades available) provides ~39.2% available oxygen and excels at producing hot, bright combustion — especially when paired with organic fuels, metals, or color donors — making it the go-to for classic, high-output compositions where speed and intensity matter most.

Key Advantages:

• Superior burn rate & brightness — Creates fast, hot flames with exceptional light output and color saturation
• Vivid color support — Powers deep reds (strontium), intense greens (barium), electric blues (copper), and brilliant whites with minimal dulling
• High reactivity — Ideal for quick-ignition, high-energy stars, flash powders, crackle, and whistle mixes
• Fine & consistent — Excellent particle size for uniform mixing, low moisture, and reliable batch performance
• Classic pyro heritage — The oxidizer behind countless vintage and competition formulas

Perfect For:

• Colored star compositions — Fast-burning, bright reds, greens, blues, purples, and whites (especially in cut/pumped/rolled stars)
• Flash & report powders — High-energy salutes, dragon's egg crackle, and burst charges (with aluminum or sulfur)
• Whistle & strobe effects — Boosts potassium benzoate whistles or metal-based strobes for piercing sound and flashing light
• Fountains, gerbs & drivers — Delivers dense, high-speed sprays and thrust in ground effects and wheels
• Aerial shells & cakes — Powers rapid breaks, pistils, and layered color effects with professional snap
• Vintage & experimental mixes — Recreates historical formulas or tests high-reactivity compositions

A precise ratio (typically 50–75% in many classic mixes, often with fuels like red gum, lactose, or aluminum) unleashes fierce, colorful fire — screen-mix carefully, granulate with dextrin or alcohol/water, dry thoroughly, and watch your creations explode with speed and splendor.

Critical Safety Note: Potassium chlorate is a powerful oxidizer and extremely hazardous — mixtures with fuels (especially sulfur, phosphorus, metals, or organics) are highly friction-, impact-, spark-, and heat-sensitive, with serious risk of accidental ignition, violent deflagration, or explosion. It is toxic if ingested/inhaled and can sensitize dramatically with contaminants. Handle with extreme caution: use non-sparking tools, tiny test batches only (grams, not ounces), full PPE (gloves, goggles, respirator), work in a fume hood/ventilated area, never combine with sulfur or phosphorus in modern practice, store cool/dry/separated from all combustibles/reducing agents, and strictly follow MSDS, pyro literature, and all local/national regulations (chlorates are heavily restricted or banned in many jurisdictions due to sensitivity). Modern pyro overwhelmingly prefers safer potassium perchlorate for most applications — use potassium chlorate only if experienced, knowledgeable, and fully accepting the elevated risks.

Revive classic pyro intensity and unmatched brightness with Potassium Chlorate — the high-energy oxidizer for builders who master its dangers and demand the fastest, brightest flames. Stock responsibly and create effects that echo through pyro history! Add to cart today!
