Dang, Julie! This light just went off in my head. I think you might be
onto something here. I KNOW those handles were straight when I attached
them.....

Subject: untwisting mugs
Okay, this might sound really stupid, but since it
happens with teapot spouts, I figure it's possible: do
mugs/cylinders unwind during firing at all? I could
swear that I put my handles on straight, and I'm
rarely inebriated when doing so, and after they are
finished, I have a bunch of seconds! They all move!
Does this happen to anyone else? I've never heard of
it before, and I'm wondering why it took around four
hundred mugs to figure out that maybe my eyes weren't
crossed, or I wasn't needing a V8, and that maybe I
actually did put them on straight. Jules

Yes, I've heard about it for years and was putting the bottom of the handle
very slightly to the left for a long time. Then I got confused and thought
that maybe it should go to the right. Do the mugs untwist or do they twist
further as they shrink? Now, I just put them on straight and don't have
much of a problem. I suppose it could depend on the clay and how tightly or
loosely you throw, how close together your throwing rings are. Since I'm
still confused about this, it would be nice to get a definitive answer. I
imagine this has been discussed before and is in the archives, but might be
hard to find.

If you want a good illustration of how much your clay will unwind, make a
mug, oh say 5" tall 3" wide at the foot and 4 1/2" witd at the rim ...like
this \ / only curved. attach the handle as straight as you can and watch
the mug as it dries, and is then fired...I'd almost be willing to bet the
handle will be crooked after the firing.
A straight sided mug would not show the twist as much, the wide rim
accentuates the movement...you can see the phenomenon on whiskey jugs too.

Tommy said about handles that twist during the firing:
"A straight sided mug would not show the twist as much, the wide rim

too."

Is this phenomenon the same as what occurs when firing teapots ... when =
the spout winds up angled away from its original position?=20
