Heather,
If the clay you throw on the wheel is concave on the bottom you trap air.
To avoid this make sure you throw down a ball of clay rather than what you
think is flat. Try patting a rounded bottom " U".
I have experienced "bubble" this occasionally by not patting my wedged clay
before I throw it down on the wheel head.

I am having a problem with a ring of air that seems to follow my finger
pulling out the bottom of a pot. I was always skeptical of asking for help
for throwing in a written form, but I am frustrated. Details to follow...
I have been throwing for 9 years and consider my throwing skills to be good.
I cone to center and then press my finger into the center of the ball to
form my hole. I then pull out my finger to form the bottom, this is when I
notice the ring of air and if I stop at that moment and take the pot off the
wheel there is a ring of air between the bottom of the pot and the wall.
What's up? This has never happened to me and I for the live of me can not
make this problem go away.
Any help would be greatly appreciated.
By the way, I am throwing on hydrobats and have this problem with anything
over 3 lbs. In the past I could throw 25 lbs. without this happening.

When you press your finger to the bottom, press your three middle fingers
so that the bottom of them are in a straight line..i wish I could draw or
something on a computer, but if you take your left hand , right now and
press down on your desk sso that your finger boittoms are all touching
the surface you will see that there won't be room for that air bubble..,
get the idea? Then you use your fingers together, not just one ,to make
that nice straigfht bottom...

Heather- you have developed a special skill! If you push this ring of air
out to just short of where you think the finished edge will be later, you
can eliminate a trimming step later- you will already have a nice
indentation next to the rim.
Just kidding, but not entirely...
Ann Brink in CA. I've had this happen occasionally, and think it was
because air got trapped when I coned down the first time.
