Solution

Sugar charcoal is the purest form of amorphous carbon. It is prepared by the destructive distillation of sugar, i.e., by heating sugar strongly in a closed container in the absence of air. On heating strongly, water is lost and sugar charcoal is left behind.
Sugar charcoal is used to extract metals from their metallic oxides.
