An oxide layer is formed on the surface of a molten aluminium alloy when it is exposed to the
surrounding atmosphere. The oxide layer on the surface of the melt is not harmful. The problem occurs when it is
entrained into the melt volume and solidifies in the casting. The paper deals with the formation of the oxide layer,
its types and the formation of a double oxide layers.
