Has any attention been paid to the possibility of assessing the age of prehistoric hearths? The method may offer a eans of radiocarbon calibration if it can be applied to a fired hearth with associated carbon.
sigh...I am told the pitcher I have was from the civil war but I cant get anyone to tell me exactly where to send it or whom to ask to date it. What do you suggest for the USA.
Too many avriables and this process would take too long to give it sufficient time to weigh the expansion. I don't think working in 10s of millagrams is good enough.

If you don't know how old it is, how do you know the temperature during its life? And do we know all temperatures throughout the ages?

what about THERMOLUMINESCENCE analysis[ TL test ]that dates ancient ceramics.
RHX is meant to complement other techniques, not replace them

Even terra cotta warriors get fat with age. :)
They look fake to me, just like Sanxingdui masks.

You can't weigh expansion.
You "weigh" the mass gain which is associated with the expansion.
