Hello everyone,
In her workshop here in Israel, Ruthanne Tudball from U.K, demonstrated how
she throws pots, using thick slip instead of water.
Can anyone shed light on this issue and explain which method is better ?
Thanks,
Naama

>Naama, As "Candy is dandy,but liquor is quicker",Ogden Nash. So slip is
superior to water since slip is simply fine clay suspended in water.
However, in throwing large pieces of finely grogged clay,water makes its
own slip in the process of throwing. We prefer a good medium thick slip. We
have thrown clays others have averred were impossible. All a matter of what
materials one has at hand. In India,I recall that mule or horse manure is
used in the clay body because of the finely divided and undigested straw
material. All a matter of taste? Don & Isao.

Let me put in my 2 cents here for throwing using slurry, not water. Solves
a multitude of problems. Basic theory........ what happens to clay when
you add water? It gets soft and slumpy and gooshy. Less water added, less
softening of the clay. Slurry contains less water per unit of "slippery"
effect ..... keeps the clay stronger. Takes some getting used to if you
are a voluminous water user to start with. I use something about the
consistency of sour cream.
I teach students to use slurry from the start.

Hi Naama,
My understanding is that slip (rather than water) is less likely to
remove the finer particles from the surface of the clay as you're
throwing. Allowing the finer particles to remain in the clay body
maintains plasticity and allows for longer throwing time.
I guess If you throw quickly it matters less.
