When exhibited to air several metals will deliberately react with oxygen in the environment to produce metal oxides and magnesium is one of those elements. With magnesium, the oxide layers are produced with the layer of white coating on the surface of the metal that will reduce down or burn with the burning manner.
The ribbon should be sanded with fine papers consequently to eliminate the layer. Burning magnesium occurs in magnesium oxide and also magnesium nitrite. Burning boosts up the metabolism from magnesium to magnesium oxide in the atmosphere.
