Clay on mon 9 jun 97
Hi Ron,
I talk to this sunrise factory's owner before they close. The amazing
things that he told me is he let all their mugs dry before they put handles
on their MUGS.
Plus they only use water & because of dry clay suck water theory, their
handles get suck on tight, tight.
-They only use Bone China which they say they shipped most of their clay
from England.However I found some RODACCO Clay box kicking around.
