That is true. Coal is composed mostly of carbon, and when it burns it turns into carbon dioxide, which is a gas. The ash is just a minor residue of the non-carbon part of the coal. Whereas, magnesium when it burns turns into a solid material, magnesium oxide; it gains oxygen from the air and therefore increases in weight.
