Getting Centered...with Support


We start with a lump of clay... that we wedge (to blend and get out air bubbles) then attach to a dry wheel. We make a round ball that we roll on the wheel first so it will attach with no air bubbles below it, using a loose wrist: wonka wonka wonka.

We get our hands and clay wet (and keep them that way until the piece is done being thrown). Any friction causes the clay to get pulled out of center!

left hand pushes away at 7 o'clock,
right hand pulls in at 1 o'clock...
both through the center

going up...

going down...

We repeat these steps until there is no wobble as the hump spins around in our hands, always with
Support Support Support!



The hands know when clay is centered

and the time is ripe for one to support
and one to open

They know from either side of the wall
when to close the distance between them

and tender the mud its almost final forming

- Mary Jo Moore




Throwing a Bowl: Support Support Support!

we start throwing by
opening up the middle

pushing down to compress the bottom...or it will crack when drying

Support even while doing the finishing steps...almost final forming

compressing the rim now and then
to let it know who's in charge;

Removing and Advanced Work

Making Larger Work with Two Pieces...this is a custom-ordered lamp base

throwing pottery debra griffin dag throwing pottery debra griffin dag throwing pottery debra griffin dag

bats are needed...
put one up-side-down piece
on another, throwing the most
clay we can for each one

after smoothing the two together,
cut off and remove the top bat,
throwing the two into one
bigger piece

after being turned over,
coils were added, thrown onto
the rest to close the top more
(see altering and glazing
to see how it progessed towards
a lamp base
)



Learning this Process, My Attempts

my teacher at Snow Farm torching
my first large item attempt (vase)
to harden the clay faster

see the large vase I made!
scary to lift it off while wet!

Waiting...

pottery debra griffin dag pottery debra griffin dag pottery debra griffin dag

drying on and off the wheel,
shrinkage happens
now
and during each firing!
(see poem by a friend, below)

bone dry greenware
ready to be bisque fired
a kiln needs to be full to be fired efficiently... pots accummulate
while waiting for this

bisqueware, ready to be glazed

waiting for inspiration and time



Fat Pot

If you go to pottery school
your instructor won't tell you the following, you'll find it out for yourself:

a pot drying on the wheel will always shrink.

You may be proud of how large a pot
you've finally thrown...and go to bed sure you've had your breakthrough and maybe you have...
but in the morning that large fat pot you thought so magnificent will have shrunk to average.
Even so, you call it Fat Pot for the rest of its life.

Just because you've never called a poem Fat Poem doesn't mean fat isn't a good thing

in a poem...once in a while...maybe.

- Mary Jo Moore
I put this poem on a fat pot for Mary Jo. Her poems show she gets it!




Altering the Surface Before it Dries

line marking

carving

sponging off after shellac is applied
and dries, shellac is not water-based
so it stays raised while the
uncovered clay washes away,
leaving grog texture

reshaping and assembling
pieces started on the wheel...
pods!

more pods!...
carving parts of these 2 sets

using extra handles as holders
for bisque-fired carved pods,
the 3 handles were attached
and fired separately before
glazing together



Glazing: All hand painted, NO dipping/mass producing

glazing pottery debra griffin dag glazing pottery debra griffin dag glazing pottery debra griffin dag

glaze test tubes, with unfired glaze
these tubes allow us to see how
the glazes look on light and brown
clay, layered, on texture and
smooth, over a rim, and much more

tubes after fired

see how they changed?

before glazed...

see below for after

for the gecho (and the face in the
other example), black oxide with
water
was painted over the
unfired glaze

after glazed...

big change, right?

after glazed...
see above for before

another surprising change



Firing: hot HOT!...and more waiting...

electric, oxidation firing

see glowing red peep holes?

the dark background is the side of
the kiln in the dark, the lighter detail
is from the top of the kiln, this is a
vent hole, air is pulled through the
kiln and is vented outside

pots after being bisque fired,
picture taken while unloading

cone 06 fires at 1791°F for 7.5 hours
it needs to cool for 20-22 hours

the kiln is loaded from the bottom up,
stacking shelves on stilts to fit the
needs of each load, pots CAN stack
and touch during this firing

pots after being glaze fired

cone 6 fires at 2171°F for 8.5 hours
it needs to cool for 20-22 hours

see the witness cones bent over at
the bottom of each picture? those
show how close to the desired
temperature the firing did,
pots CAN'T touch during this firing



how a few finished pieces are used...bringing comfort and more!
