The "metallic glass" name has nothing to do with transparency; the reason it gets this name is that its atomic structure is identical to that of a glass. The atoms in glass, liquidmetal and for that matter liquids, are not arranged in a regular ordering like most solids are. They have an amorpheous structure, where the atoms are "frozen" in a random network.
