## the perfect coil

### Longtin, Jeff on fri 10 may 02

Seeing a few "roll a coil" comments being posted reminded me of a trick I
learned years ago.
In college I learned how to roll the "perfect" coil, I wonder if anyone else
has similar tricks?
To roll the perfect coil, I learned, you never roll the clay, on the table,
farther than the circumference of the coil.
The circumference, remember, is roughly 3 times the width.
If the clay coil is 2 inches thick when you begin you would roll the coil NO
MORE than 6 inches. When the coil is down to 1 inch in width you reduce your
stroke to no more than 3 inches. When its down to 1/2 inch thick you roll
no more than 1 1/2 inches, and so on and so forth.
At first its a tad annoying to think about the math but once you get the
hang of it you can roll really nice coils really quick.
Give it a try next time you can't seem to produce nothing but those oval
things that seem to result when you roll too fast. It really works!
Take care

That's funny, a while back someone else on ClayArt said the key was to make
sure you DID roll through more than the diameter of the coil.

IF PERFECTION IS A ROUND COIL THEN THE BEST WAY TO ACHIEVE IT IS TO =
EXTRUDE IT.
