I think the oldest thing that I have is a part of a piece of pottery from Pompeii. It is a clay spout from some kind of vessel. When my dad was a child, he took the “Grand Tour” with his mother and grandmother and they stopped in Pompeii. He was about 10 years old and probably one of the only children around. He was a very curious child and interested in History, so he got to talking to one of the archaeologists at the site and he gave him the piece of pottery as a remembrance.
He grew up part time in the Philippines and also found an Asian iron tea kettle when digging on the property. I’m in the process of finding out how old that is and something about it’s origin.
