Well, Morrowind(unfortunately not Oblivion*) had glass weapons and armor, though damned if I know how or why that's practicaly.
I've got Tatooboard a pig iron short sword.
This is a pig iron short sword. All craftdwarfship is of the highest quality. This item menaces with spike of dog leather. On the item is an image of Cusith Frogshell the human in pig iron. Cusith Frogshell is traveling. The artwork relates to the journey of Cusith Frogshell to The Barbed Fissure in 161 during The Third Journey of the human Cusith Frogshell. On the item is an image of the ùshrir Axepack the dwarf and dwarves in pig tail fiber. ùshrir Axepack is surrounded by the dwarves. The artwork relates to the ascension of the dwarf ùshrir Axepack to the position of queen of The Deified Road(our civ) in 187.
There's also Pastworks, an iron buckler. No art, but it's encrusted with jelly opal and encircled in bands of iron. And The Permanence of Curiosity(dog bone left gauntlet, no decorations) and Lastwomen(oh jeez) the cave spider silk toga(decorated with CS silk, bands of giant toad leather, and an image of dwarves in white chalcedony).
*Explainable by the fact that the "glass" they used was mined volcanic glass possibly unique to Red Mountain. It was likely hard to work with, and ebony was both far stronger and more readily available. So glass seems like a considerably less lucrative export to Cyrodil than ebony was, despite ebony's own difficulty in using. "Elven"-type metal was probably more practical and cheaper in Cyrodil and was imported most likely from Summerset(or reclaimed from Ayleid sites, which are absent from Morrowind), and the distance between Summerset and Morrowind(in addition to probable dislike between Altmer and Dunmer) meant that little or no "Elven" items would have made it to somewhere as remote as Vvardenfell.
