This oxide film forms a protective barrier against further oxidation. When melting aluminum, the exposed surface of the molten metal will oxidize to form dross. This dross may float on top, sink to the bottom, or it may become mixed in the melt. If the dross is not ³wetted² by the aluminum it will float.
