A client in Wisconsin wants to ship me a couple of opals to make a piece for him and he had an interesting question:
‘Is it safe to ship opals in very cold weather?’
I haven’t had a problem with this YET.
However… Obviously it could be an issue, especially with ethiopian material which I have seen have up to a 10% weight change from very dry to very moist conditions.
So: Has anyone had opals break in transit due to extreme cold weather?
