A deflagration spoon is used in chemistry experiments when the burning of phosphorus, sulfur or another substance is required. It is capable of withstanding high temperatures and is equipped with features to facilitate working in this environment, such as a long handle angled to keep heat away from the hand.
Deflagration spoons may be used in combustion reactions. These are chemical reactions where a compound and an oxidant react to form a new product. They are exothermic reactions, so they also give off heat. Sometimes, the reaction is slow and there is no noticeable temperature change. Oxygen is a common reactant in combustion reactions.
