Where do you get glass weapons in oblivion

i got a glass war axe at lvl 10 at vilverin near imperial city usually when you get up to about lvl 15 you can get glass, elven and dwarven from bandits i think that if you are really struggling have a look around in the heartlands or great forest area for elven ruins enter them if its a skeleton go back if bandits fight them some ruins i have found are: Anga, Vilverin and Kemen oh if you are also after daedra try looking a bit above Kemen for a daedric shrine
