Fusibility
Except in a few instances, all solids which can bear a high temperature without suffering a chemical change may be melted. Even carbon has been partially fused before the oxyhydrogen blowpipe. Most solids when heated to fusing-point change at once into perfect liquids; whilst others, such as platinum, iron, glass, etc., pass through an intermediate pasty condition before they are perfectly fluid, making it difficult to determine the exact fusing-point.
