Yes! Powdered sugar is flammable due to its smaller particle size and greater surface area. In the right circumstances, it can even be explosive. The same doesn’t apply to Common table sugar (sucrose), which is considered non-flammable. This post will cover everything you need to know about sugar in terms of flammability.
Liquid sugar is a sugar suspension that contains juice and sugar syrup. Liquid sugar is not flammable and has an auto-ignition temperature of 932 degrees Fahrenheit (500 degrees Celsius). According to this safety sheet , it is not considered to be flammable and while, again, it will burn if you heat it enough – there’s nothing to be concerned about in ordinary usage.
Is sugar flammable/combustible dust ? Can sugar catch fire?
Yes, sugar is flammable if it is kept under certain conditions. Crystal sugar is technically not flammable. However, powdered sugar is more volatile and even more explosive in some cases than table or regular sugar. Let’s jump into the details.
Granulated table sugar won’t explode by itself, but it can ignite at high temperatures, depending on the humidity and how quickly it’s heated up. (Powdered sugar is marginally more dangerous.)

What happens when you burn sugar in a fire?
Extreme heat forces sucrose to decompose and form a volatile chemical called hydroxymethylfurfural, which easily ignites and sets the rest of the sugar on fire. ( Some see a potential biofuel in HMF.
Is sugar flammable?
Common table sugar (sucrose) can catch fire at 662 degrees Fahrenheit (350 Celsius), which means that it is not technically flammable. However, powdered sugar, due to its smaller particle size and greater surface area, can be flammable and even explosive in certain situations.
Why does sugar explode easily?
This is enough even to trigger an explosion in a cloud of sugar dust or powdered sugar. Not only does powdered sugar explode easily, but so does that other staple of baking – flour and for much the same reason, the powder makes it much easier to ignite due to extra oxygen.
What happens when you burn sugar in a charcoal stove?
The resulting sticky material takes on a brown color because the sugar is partially burned in the process. If you keep your stove on a low setting, the sugar will eventually become charcoal, in the same way that logs can smolder without actually catching on fire.
