The present disclosure relates to a method for forming a glass structure having a metallized surface portion. The method may comprise forming a structure using a flowable first material, adapted to form a glass, which includes a metal component. The structure is then treated to remove substantially all solvents and organic components contained in the first flowable material. Finally, the structure is exposed to a bath of a metal salt during which nucleation occurs and a metallized surface coating is formed on at least a portion of an outer surface of the structure.
