Hello... I have a broken piece of red clay pottery with arabic
writing on it that I personally found in a desert in the middle
east. It appears to be half of a cap for a walking stick(educated
guess). I was wondering what it's oldest possible age could be? If
anyone is interested in carbon-dating it or even translating it,
let me know. Thanks.
