Ivor,
I have never heard of or seen
this technique, using the coin,
but sounds interesting. We
were always told to measure
the bottom with a needle tool.
I didn't like that, I just developed
a "feel" for it.
I use wet clay purchased from
a company in NC. I recently
tried a new clay that was half
porcelain and half stoneware.
Wedging isn't necessary but
I like to this to soften up the
clay and shape it into balls.
I had no problem centering or
throwing this clay. I followed all
the "rules" I mentioned in my
previous post. Imagine my horror
when, after bisque firing, every
bowl had spiraled cracks, not
s cracks, but swirling spirals.
You could see where I had
wedged this clay. The cracks
were not all the way through the
bowls, so I use them in my home.
The clay had "remembered".
Oh yes, these bowls were thrown=20
in the spring, LOL.=20
