I've scoured the internet for a proper chemical reaction between caramelized sucrose and Potassium Nitrate for the past few days. So far, every chemical reaction I see drawn out is between pure sucrose and potassium nitrate, while the smoke bomb in question requires caramelized sucrose, an entirely different thing altogether that probably will give you a different reaction.
Am I over-thinking this, or is Caramelen/Caramelan the reactant, instead of sucrose? If someone could be so kind as to draw out the chemical equation between the two, that'd be awesome, too. (Heat is part of this equation, as the substance is lit to produce the smoke)
