A molten metal feed pipe for feeding a molten metal of an nonferrous alloy includes an outer tube made of a ferrous material, an inner tube made of a molten metal resistant material, and an intermediate member made of a compact of a fibrous non-organic material, which is disposed between the outer tube and the inner tube. The intermediate member, positioned in the central region of the molten metal feed pipe with respect to the longitudinal axial direction of the molten metal feed pipe, is disposed between the outer tube and the inner tube with the intermediate member being compressed in a radial direction of the molten metal feed pipe.

A glass-shaping mold includes a steel base member, and a crystallized, machined layer, an intermediate layer and a mold-releasing layer which are sequentially formed on the base member. The machined layer is a layer of nickel alloy containing phosphorus. The intermediate layer is a layer formed of chromium, nickel, copper or cobalt. Alternatively, the intermediate layer is a layer of an alloy layer containing at least one of these elements. The mold-releasing layer is a layer of an alloy containing iridium and rhenium.
