An improved mould (10) for use in the production of glass containers such as bottles, jars and the like, the mould (10) includes at least one mould surface defining a cavity (14) which is adapted to receive molten glass, and in which the mould (10) surface is provided with a coating (16) over substantially the whole of the surface, the coating comprising an alloy. The mould (10) is made of segments or partial sections - preferably of two half bodies (12 12a) - with a hollow space (14) in each segment or half body (12, 12a). In the hollow space (14) the coating (16) - comprising an alloy of cobalt and nickel - is metallurgically bonded to the mould (10). The process for producing the mould (10) includes that the coating (16) is fused to the mould (10) by using a two-stage process in which a powder containing the constituent elements of the alloy coating (16) is initially provided, the powder comprises a specially formulated alloy powder in which each particle essentially comprises the elements of the final alloy coating (16) or the coating (16) comprises one or more different powders which maybe mixed together.
