  The oldest that I have found would probably be Medieval pottery and glass and things. The newest would be the finds from the WWI excavations, so bullets, glass, penknives, gas masks, grenades…etc.
  
  The oldest I have worked on was Egyptian material. I was given a pin-like thing and asked what it was. I still have no idea what it was, but it was made of metal.
  
  The newest I have worked on would be the experimental glasses that I made earlier in the year.
