Good morning,
I am posting this for a friend who has been digging some local clay .
blunging it and then putting it through screens.
The clay is very plastic, throws well straight from the ground, and seems
mature at cone 04. Takes a white majolica glaze perfectly...BUT...
there are lime pops that form after the pot sits for a day or so.
They rise to the surface of the glaze and can be crumbled with a fingernail.
( I am making an assunption that they are lime,,or some form
of calcium.)
Is there anything that can be done to solve this problem?
I know this information is sketchy but any thoughts are appreciated.
The clay is actually wonderful to work with...I got a few pounds
from him in exchange for testing it in my 'lil test kiln.
Thanks in advance for your help.
