Consider the example burning of magnesium ribbon (Mg). When magnesium burns, it combines with oxygen (O 2) from the air to form magnesium oxide (MgO) according to the following equation: + () Magnesium oxide is an ionic compound containing Mg 2+ and O 2− ions whereas Mg (s) and O 2(g) are
Magnesium ignition remains popular among amateur thermite users, mainly because it can be easily obtained, [17] but a piece of the burning strip can fall off into the mixture, resulting in premature ignition. [citation needed] The reaction between potassium permanganate and glycerol or ethylene glycol is used as an alternative to the magnesium ...
Magnesium is highly flammable, burning at a temperature of approximately 3,100 °C (3,370 K; 5,610 °F), [2] and the autoignition temperature of magnesium ribbon is approximately 473 °C (746 K; 883 °F). [3] It produces intense, bright, white light when it burns.
Magnesium block heated with blowtorch to self-combustion, emitting intense white light. Magnesium metal and its alloys can be explosive hazards; they are highly flammable in their pure form when molten or in powder or ribbon form. Burning or molten magnesium reacts violently with water.
Thermate can also utilize magnesium or other similar elements in place of aluminium. In addition to thermite, thermate sometimes contains sulfur and sometimes barium nitrate , both of which increase its thermal effect, create flame in burning, and significantly reduce the ignition temperature.

Accroides resin , higher burning rate than shellac, burns well even with potassium perchlorate. Suitable for chrysanthemum stars. When metallic fuels are used, the metal particle size is important. A larger surface area to volume ratio leads to a faster reaction; this means that smaller particle sizes produce a faster-burning composition.
"A significant danger of magnesium ignition is the fact that the metal is an excellent conductor of heat; heating one end of the ribbon may cause the other end to transfer enough heat to the thermite to cause premature ignition." I removed this from the ignition section of the article because it is incorrect.
