Hello Anji,
Thanks for your idea. You are right, that plaster chunks in clay do that. =
But,
no, that was not it, although I do wedge on plaster, careful to never use =
metal
tools and ribs to scrap it up with. Thanks to good information from =
Clayarters
familiar with these bodies, they told me it is a problem called lime popping=
or
lime spitting. The lime from firebricks used for grogg. I have been =
eternally
frustrated by this. I thought it was something in the clay just not broken =
down
enough and I could correct it by maniac wedging. At least I can stop all =
that.
Luckily I only have about 100lbs and have 50 lbs. left. I will try =
something
new. Thanks again for your input.

Alisa,
I guess you have been hit by the Potclays bug, in a post from
Janet Kaiser she inquired if maybe Potclays were getting rid of bad clay
[contaminated] by shipping it abroad. The answer to this is YES. We in
Ireland were receiving contaminated clay for years and eventually a man who
used to be their export manager,admitted [by default] that they had a lot of
White St. Thomas body, which was the clay I was using, that was contaminated
and he would me this at a quarter of the full price. I described the
contamination and he replied "yes that is the stuff", I then told him I had
been buying this clay for quite some time and each time I complained I was
told by Harry Fraser that the contamination was coming from my workshop.
Harry Fraser eventually said he was sorry but the staff in the shipping yard
must have been putting bags of the contaminated clay in with the good clay
and he was unaware of this.
I now get my clay from Dobles in Cornwall and will recommend it as the
best clay I have ever used bar none, the plus side is they are a pleasure to
deal with.
Regards,
Bob Hollis
