Does anyone have any ideas how I could go about getting the slip on
thickly without the cracking
and peeling?
I have been slip decorating on my pots - and my method for keeping things
simple is to use the slip in the splash pan - Yes, the very same material
out of which the bowl or plate is made. Has to fit. I add colorants,
wait to wet-leather stage, brush on a layer of unstained slip, then add
the colored slips. I haven't los pots due to this ever. ?:-) But
usually, it's not more than 1/8" thick.
Hope that helps.

Okay, I don't know who all works with ceramic slip. But my question is,
My slip is having a big problem. It has been settling in the bottom of
the mixer. And very runny on top, and there is a black film that is
forming on the top. DOes anyone know what is happening? Any help would
be appreciated.

Hello All,
A former student mentioned that her new ceramics teacher used vinegar
instead of slip. Since As a ceramics novice and despite my research, I have
not come across anything like this. Is there a recipe for a vinegar
solution that can be used in place of slip? If so is it more effective than
slip? Does it work better on certain clays?
Thanks for your replies!

Janine,
Vinegar can be used for joining pieces (such as handles) in place of
slip, but not for decorative applications as far as I know.

PMFJI:
I learned when I was in school that adding vinegar to a slip (small
amount of slip, small amount of vinegar, don't remember any proportions)
was useful when 'gluing' two slip cast parts of a piece together.
e.g. a cast cup with a cast handle, gluing the handle on while still
greenware using a little special mix of slip with vinegar in it
supposedly helped in some way to create a better bond for firing.

Hello Janine, I use a vinegared slip solution instead of just slip or just
vinegar. I have a covered jar which holds about 1 cup, and peridically add
more slip and a squirt of vinegar. Over time there is a lot of bacterial
growth in there and I believe it helps to attach appendages very securely.
When Malcolm Davis was here last spring, he was mending a broken teapot
handle with it, (in the greenware stage) and it worked like a charm.(He
even said, My G-- it's better than Malcolm's Holy Water!!) I make a lot of
teapots, and rarely do I have any cracking using vinegared slip. About 1
tbsp.to a cup of throwing slip. Try it and see. Best regards, Liz

I have found that vinegar is great for repairing
greenware and joining handles etc. that have dried just
that little bit too much,regardless of climate.

We use spooze quite a bit, with good results, but primarily as a repair
medium for bone-dry stuff. I have never used it as an ordinary joining
slurry, but I'd love to know how it works if someone wants to try it.
Spooze is composed of your claybody, pulverized dry, moistened to the
desired consistency with a 50/50 mixture of vinegar and corn syrup.
Good luck -

Hi all,
Does anyone have recomendations for a cone 10 white slip to fit on Amador
clay (red) body? I'm not sure how slips and clay bodies work and what is
needed to make a good fit, but porcelain slip caused crazing (is my
uneduacated guess). I'm wanting to experiment with a high fire
majoilica-"type" application at the community studio I go to where they
work in high fire reduction. However,the white there does not cover the red
clay body I like to use well enough. So I thought slip might help create a
more uniformly white surface to apply stains to. Or am I barking up the
wrong tree?
with much continued appreciation of the educational value, not to mention
the kindness, of this list,
Centa

I have lost the recipe I copied off this list for a slip consisting of
clay,soda ash and sodium silicate. I tried the clayart archives but I
still can't find it.
Help! Does anyone still have it?

Here's a recipe that was posted here awhile back. Maybe it's what you're
looking for:
DEFLOCCULATED SLIP
Dry Clay 2
Water 1
Sodium Silicate .5 % of Dry Clay
Soda Ash .5 % of Dry Clay

Just wait a minute.
Of course slip can be made from a clay body, but not necessarily
from ANY clay body. For one, any and all grog needs to come
out....
Of course slip can be applied to leather hard clay--as well as
greenware and bisque.
Unlike glaze, mixing slip is pretty foolproof. So you do not
need fancy equipment.
Here are two recipes I use, have used, both of which are measured
out with regular kitchen style measuring cups or similar vessel.
The measuring cup is filled with a ladle or spoon. The material
is NOT scooped up. BOTH are for leatherhard clay.
Potash feldspar 1 cup
Ball Clay 13 c.
Kaolin 3 c
flint 2 c
Zirconium opacifier 1 c
Bentonite 1c.
I use Tenn 10 Ball clay OR XX Sagger as I like the slip to be
white in the raw state.
Robin Hopper Slip, adapted
Feldspar (either soda or potash)
Ball Clay 8 c
Kaolin 1 c
Flint 1c
I add 1/2 c zirconium opacifier to this base.
I am puzzled why your slip peeled, flaked, whatever it did. Maybe
your recipe was for leatherhard clay and you used it on
greenware? Or something like that? Maybe the surface was too
polished? So that the slip adhered badly? Maybe you put it on
too thick? This is a puzzlement--but some slips can take very
heavy application, and some can't.
If you are going to apply the slip to greenware you need to get a
recipe for a slip meant for greenware. I know there are some in
Rhodes' book. Probably in others. Pottery Making Illustrated
just had an article on slip decoration...so look there.
Good luck
