<p>The invention relates to a wash, at least comprising: a carrier liquid; at least one pulverulent refractory material; and at least one reductant. If a casting mould is coated with said wash, reductive conditions are created by the reductant on the boundary surface between the casting mould and the molten metal, thus suppressing gas formation and leading to a lower degree of gas entrapment in the metal. A lustrous carbon former is preferably used as the reductant.</p> |
