I want that wall hanging bowl. The textured and
wobbly.Ice breaker: favorite cookie?He has over the years switched
to earthenware, firing lower,
using oxides."One thing I didn't think
about is that my kiln is going
to last forever"He kept turning out 2 phase and
three phase power and.... yeah, it's been a thing!"They're a blue color clay"
He says Pete Pinnell found
They're just as durable.- the red clays are the
most popular clays in the
world! They're right on
the surface, easy todig up.Someone is arguing w/ him
about porcelain vs earthenware -
he says compression force is what matters, and changingLinda Arbuckle has a great speech
on line baout the joys of red earthenware."I don't use a splash guard, I think you guys are a good
distance away (you should be fine)"

Small cup- he thro opens up w/ his two thumbs!
- he leaves about a half inch
- tea"Bowls and plates Want to happen. Cups you have
to make happen."
"Every brush I own is someone else's" (every studio)he likes the rubber
yond for smoothing
the inside (its vegan)he'll decorate
on the pot
w/ buttermilk
thicknesshe likes the
chip brush w/
pig bristles
ro 'it just
leaves so
transpurent
for need of
dry clay to
show throughhe likes the vertical
quick motion b/c he gets
lots of interest w/ one
technique: color, stripes, etc."How you sture your pot will encourage what you
do to it next."
- he likes to alter, so he uses plastic bats to keep
it wet longer.

Vertical Cup
- double thumbs again. He wants that "coved l/ interior.

Plate- "You're Not gonna throw that on the
bat?" - "No. I'll show you why"= Use the Phat Rib
on the inside
= back again with the
bush on the insidepick

Wet Chuckits just a form for trimminghe said somethingabout taking aloupe tool andturning it "in"he finally "whalecote is & "tales so that itdrains when in thedishwasher.Just one.Something forhis pinky toplay with hesays.I ain'tgot time forthat.Handles- he rolls out cylinder- mostly he shapes in and compresses"When you score, make a mess"- its not a glue, its a catalyst foren exchange if water.- His cup is pretty stiff, and heattaches well, presses, smooths,not pulling down, pushing into thatconnection.- He adds water, does the flats and the edge,until he can make the arc.- there is no room for the hand but hisitts goodgoing to stretch it out.

Trim a plate
- pro foam bat.
- for bowls and plates.
- he likes this ble his rims arent flat and he wants 'em to stay that way.
- he is a light trimmer, but I think he's pretty heavy. He trims inside until it starts to give.Stacking: "I do three or four that's is high as I go"Chis mother in law would stack ten plates! High)."I want my pots to be all about softness or roundness"(as opposed to hard or sharp edges)- he stamps in the middle w/ his Roman "R" and he thinks it might help w/ S-cracks.Slip Decorating- Oestreich ~ he does for dipping (as opposed to the - he thinks of dipping for solid colors (brushing in didgion)
- terra sig does'nt like to go over slip, so he thinks about leaving a bare area for them.
- Thicker Slip holds water longer - things like handles might fall off on a dip. Again he goes w/ a thicker thinner slip.
- Dip slow, disengage slow.Choices:
Image 7
Brush Away
- dip, put it on a banding wheel - do not dally!
- use bristle brushes, clean between strokes.
short strokes
- It pushes the Oostreich out of the way neat
"I don't rush things"
- no sun dry
- no force dry
- no fan
- no heat gunPaper Cut
- he likes newspaper
- he then brushes.
- why wait... peel it off
as soon as you can.handles:
- he brushed
around them
- too hard to futz it
up.
- for black slip he
goes thicker bc
you can't really
see thru to it.
"Barner black slip"
Shing - harner clay - coball
Sodafire - nepheory - black- I like how this
decoration fades
into the un brushed
clay body below.
- another color
combo: chartreuse
and black and
there is red clay in
the brush gives a
pink tint!

Slip Trailing
- gives him: color, line, texture all with one technique
- He uses Porcelain for slip trailing (not Oestreich) - warm
yogurt
- He always screens his slip - its the kaolin he was
told. 60-80 screen. He uses brushes to push it thru.
- He adds soda ash too, which defloculates. A pinch
per quart of slip.Cynthia told him "You're wearing your screens
out w/ that bib."Lisa Orr is
amazing to w- he adds copper
to the slip, and
this migrates to
the edge
1 Tb copper to
1 cup of slip.-For cobalt its
1tsp to 1 cup"If you mess it
up to
and you try
fix it immediately
you'll make
it
worse."- let it Wait.- he's using
a coral
slip

- Vince Petelco wrote a
whole article about terra
sigillatas if you wanna
get all detailed about."Clay bodies are clay,
but they've clay
bodies"(ie, they got more
than clay in 'em)- terra sigilata → italian seal
paint, basically. → pre glaze
technology.- use natural brushes w/ Terrasig. Moppy is good. Its
mostly water.- he's all about paint by numbers: three colors.- he says terre sig is a
little clear... you can do
two different colors and
they mix (blue, then white,
say).- slip terra sig catches some
interactions. a slip won't. (lithium

~ Nuances ~- Sigs are sensitive and thin, they melt into the glaze- If you want bold colors use slip.- Sig is food safe, but it'll wear away more than a glazed surface (white red terra sig - probably less the cobalt and coppers!)- Slips...are brittle, they gotta be glazed.- Low firing is less shrinking, less stress. Where earthen ware shines."I don't do that pour in roll around buziness that Cynthia Bringle does. I just pour it in, and out.Its not sexy. Its not cool. But it's not messyGlazing- he uses a really really thick clear (CM clear - low fine clay makers clear) so it brushes on neal well.terra sig.- he lined it first w/ a romal glaze- he gets a lot of success out of two
glases touching each other - his dots
are one glaze, but the dip is another glaze."People are always talking about how messy red elays are - keep your white porcelain away from me. That stuff gets everywhere."her

- he finds dots of glazes with lithium or copper
in it will migrate to the edges. In an electric
kiln.terra sig erazes totGlazingGlaze:
- Usually he uses an amber celadon
as the big to dip
- he has waxed dots on the very bottom
- then brush a thick
crackle glaze on the
underside of the bowl
Shape ONCE (fiddling
equals cracking)
- he wads the bottom and
puts it in the kiln
(immediately the glazes
are very brittle)Fine: low fire (cone 03-?)
