throwing large pieces of clay

Ah Youth........I used to be able to throw more than 40 lbs. Now, I've
either forgotten how or my 51 yrs are saying "you ain't gonna do it". Are
there any videos out there that will help me throw large spheres? Maybe a
video on how to manage large pieces of clay on the wheel. The next
obvious step is coiling and throwing or just coiling and yes, I will do
that but still........ I would like to be able to grab a box of clay and
"just do it" like the good old days of my youth.

Don,

Robin Hopper has a tape on throwing large pieces. It's called 'Advanced
Throwing on the Potter's Wheel - Extended and Altered Forms'. He
demonstrates sectioned pots, pots extended by using coils, and pots extended
using slabs. As always, I thought this was a very good tape.

Don't get much time to talk these days with show season and all, so thought I
would ramble for a minute..

Don, I saw a tool in Axner's catalog that will center mondo lumps of clay and
drop the hole in them, leaving the rest for you to enjoy...it fastens to the
table in front of the wheelhead..

I'm just a bit older than you, but I think I could center 40 lbs. of clay...I
just can't face the cracking at that size....I did find a twin bed size piece
of 3" foam at a garage sale this spring for $3. I put some of it over one
shelf I use for drying and cracks have been reduced in my pots by 80%. There
is really something to putting the pot down to dry on something that will
shrink with it...especially for the wide flat bottoms on big casseroles....

Disclaimer....I don't have any financial interest in Axner - just like to
shop there..

While I'm commenting, our local building supply here sells round pressboard
bats in many sizes from 6" up to 36" and they are not very expensive. I use
24" ones on a gallon plastic pail on the table in front of me to move small
pots to. I stack four of them and I can turn them and move them when
full....works for me...

Extruding has turned out to be a wonderful tool in the studio. I am still
trying to get my slab rolled pieces right, but am having trouble....the
rectangle pieces will do just fine, but the large elipse still warps when
drying.I don't seem to be able to get a decent bottom on the pots.....I am
turning the clay and rolling it like a pie crust on all sides. Could it be
the clay is not thick enough? How thick should it be? I have been throwing
on the round hump molds and plate molds and I like the results... ...While
we're talking about it, I knew a fellow a few years back who would throw his
bat molds and slump molds. He would throw the slump molds in pairs so they
would match perfectly and produce a wonderful round ball when the two pieces
were put together. After he threw the molds, he would bisque fire them and
use them like that...works really well for lumps of colored clay pounded into
them...

Let's get it all....what is rigidizer?....I am firing my new to me L&L 27x29
kiln and the effects of the slower cooling are very noticible....I was
talking with a fellow potter at a show two weeks ago and he said to slow it
down further...either by getting another lid to sit on top of the existing
one during firing or at lease putting kiln shelves on top of the lid while it
fires. Could I cut some fiberfax and add this rigidizer? can I wrap the kiln
with it? Am I getting in trouble?

I have some glaze recipes you all might like that I'll post in a day or
so..and I do have a cone 10 celadon recipe that I can send...I also have a
nice blue slip that feathers into the GB/EPK/Silica recipe....
