Cindy in SD on fri 29 apr 05
I've included the two previous posts because this makes no sense without
them. I wondered about this when I read it, too. I also doubted that
removing the throwing lines was the reason the spouts weren't twisting.
I wonder if it could be that the rib pressing against the dowel inside
the spout during the final throwing caused enough compression that it
prevented the spout from "uncoiling" later? Just a thought.
I usually don't throw spouts that will have a directional curve at the
end. I pull them like a handle, wait for them to get to leather hard,
then cut them sagitally and hollow them out and rejoin them. I know one
can get used to the curve and get pretty accurate at compensating, but I
never could seem to get them perfect. My husband says I'm
obsessive/compulsive. My customers never noticed, but it really irked
me. Anyway, I only throw spouts that will remain unaltered. My little

Cindy - what do you mean by "sagitally"? My dictionary defines "sagital"
as "of or relating to the suture uniting the two parietal bones of the
skull". I can't relate this definition to a teapot spout.

Sorry, I guess that was a bit obscure. Think of the direction of that
sagital suture, then imagine it continues all the way down, dividing
your body into two halves. That's the way I cut the solid spout in order
to hollow it out. This way, the pieces are bilaterally symmetrical. No
real reason you couldn't cut the other way--whatever works best for you.
