slip, slippin' away

I have used slips all my life. I have combed them, used paper resist,
layered them and always thought why do I use them? They are messy and
unless timing is right you can wreck a lot of pots. Rims of bowls too dry
and slip added and ya get rim cracks. Put the slip on when the piece is too
soft and you find your beautiful round teapot slumped in a puddle on the
table. As many of you know I am in the process of reinventing myself as a
04 e-ware potter. My first step is to develop the slip. Everything comes
after that. My plan is to dip and pour a slip on the e-ware. I'm after a
soft yellow colour not a clinical white. Once I get the slip right I think
the rest will follow. I'm thinking I will need a garbage can of the slip,
garbage can of terra sig and a garbage can of a good clear. The other
colours will be in ice cream buckets. Going to try to keep it simple.
Sancai- 3 colours. I want to show that beautiful colour of the red clay as
much as possible. I do like the colour of low fire red much more than the
grey of high fire stoneware.
We have a retrospective at the Burlington Arts Center in May. I don't have
a single pot made yet!!!! Once it is all in my head the pots will
flow.Right now it is back to the studio to insulate. Lots of grunt work
before I get to make. I'm getting edgy.
Ciao,

Tony,

For some time, I have used a white cone 6-9 stoneware called
Superwhite for my inlay and hakeme on iron stoneware. I buy it dry
and just add water as I need it. It is also a good woodfire and soda
flashing slip.

I have also used Continental Clay's white earthenware I buy dry
on their terracotta body as a slip. You might give that a try.
You can easily change the color by adding a small amount of Redart.

I also use Redart Terra Sig on the terracotta for my pie
plates. It is the original Teflon! To jazz them up a bit, I fire
them on shells to cone 1. You actually get localized flashing!

I am working on celtic earthenware that is more genuine than
the souvenir stuff you usually see. Looking at bronze age stuff is a
real inspiration. These should fire up nicely in my TorchBearer.
Will also experiment with them in lowfire soda (it is one of the
reasons I fire to cone 1, along with the fact that it make the work
more functional.)

Further to why slips. I find they offer a depth of surface that allows the
use of one glaze. I also am better off when the decoration has been decided
when I make the work. There is nothing worse than me standing there with a
bare bisque pot and a variety of glazes and a paint brush. That spells butt
ugly.

Lee and Bob: Thanks for the info. I had a student last year use this slip
and it was very lovely for her work- a bright white and she did line
drawings of flowers and birds thru it. It was very white and shiny.

Halifax White Slip



30 Ball Clay

10 EPK

30 Talc

10 Neph Syn

13 Silica

02 Zircopax

05 Frit 3124

I have taken out the Zircopax and used 32% of the high iron AT Ball clay
from England. (I have 2 bags I've saved for over 20 years. Just trying to
keep the formula at 100. I will add some rutile and either a dash of
Redart or some local clay called Queenston shale which is everywhere. I may
use that as my sig. I liked Lee's comment that sig was the original teflon.
There was a Medieval lead glazed piggy bank with chickens on it at The
Royal Ontario Museum that stopped my heart. If I could come close to that
piece I'd be a happy camper.
thanx everyone. Hey, I always share so what's mine is yours. That is why it
is always nice to add a local material so that even if you share the person
can make it theirs.
Ciao,
Tony

I sometimes use terra sigs on bisc, even sometimes buff them up to a =3D
nice shine with my sham-wow. For instance I thin my red sig to watery, =3D
apply it to 05 bisc and then fire to 5. It doesn't flake off unless it's =
=3D
too thick.

Amen, brother. Testify!

I don't know if its an issue of patience (as in lack thereof) or the fact=
=3D

that when you are applying it, glaze doesn't even remotely resemble it's =
=3D
end
state (colorwise), thereby making it difficult-to-impossible for me to
adequately visualize the end result.
