Paul,
Here all Ceramic materials are required to include at least 5% moisture when shipped as a measure to reduce dusting.
I would suggest the manufacturers might possibly up that percentage on exported materials; as they spend longer in transit, and so could be more liable to dry out before the point of sale.

Hi John,
As I understand it, silica bearing materials are shipped wet in europe
for safety reasons, to guard against inhalation and silicosis. I know
the last time I got a bag of cornish stone from Laguna, it came wet.
Can any of you from over the pond confirm this?
Best wishes,

Hello,
I use a glaze here called kimachi. It is a black glaze made from a
single material, a type of stone. I have heard an equivalent is Cornwall
stone. Does anyone know if that is actually the case?
Thanks,
Dave
