1. A pseudo-reference electrode comprising a pseudo-reference glass material backed by a silver conductor comprising silver metal,
wherein the pseudo-reference glass material is:
a chalcogenide glass comprising a silver chalcogenide Ag2Ch, wherein Ch denotes a chalcogen, or
a halide glass comprising a silver halide and at least one glass-forming oxide of a metal or a metalloid,
a mixture of two or more of these glasses, or
a composite of at least one of these glasses.
