I am just starting a home studio and want to work primarily
in red earthenware...the problem is without all the equipment
I had at school how do I make a batch of terra sigillata
without a plunger and a ball mill...is there a way to make it
with stuff I have around my home and in my studio?
Any help with this situation will be very helpful to get
me started producing!!!!

Take some of your "fine red earthenware clay", mix it up with LOTS of
water, at least 2 parts water to 1 part wet or dry clay (it really
doesn't matter).
Mix it up REALLY well, with a jiffy mixer or such. Let it settle and mix
again, settle and again. You want to get the water to breakup those clay
particles as much as possible.
Mix it again REALLY well and add about a teaspoon of Sodium Silicate per
2 litres (or I guess 1 teaspoon per gallon in your case) and mix some
more.
Pour into the biggest, tallest clear containers (I use 2 litre pickle
jars) and let settle for about 24-36 hours.
It should seperate into 3 distict layers, a very thick, goopy layer on
the bottom, the terra-sig in the middle and a very watery layer on top.
Siphon out the middle layer and you have your terra sig ready to use.
Do the same with a white burning ball clay if you want white sig. You'll
probably have to use about twice as much water as with the red clay and
it might take longer to settle out.
If you mix the "goopy" layer up again (difficult) and add some epsom
salts until it doesn't settle any more, you'll have a coarse slip that
you can apply to bisque!
I'm doing all of this and it works for me (the usual disclaimers apply
;-)
Good luck.

Hi Leesa:
This is how I make terra sigillata. With a container of water, preferably
rain water or distilled dissolve enough Water softener such as Calgon until
it feels slippery when you place your fingers in it. Then sprinkle the clay
you plan to use and stir well. Allow this to stand for 24 hours so the water
separates from the clay and then you can syphon off the water. Use only the
top 30% of the remaining clay. This can be siphoned off also. Allow this to
evaporate and thicken and then its ready to use. Some potters op to ball
mill this mixture but if you follow these directions you will have good
results.
Good luck. Terra sig is a great way to decorate and burnish.

Hi, Lisa:
It's very easy to make t/sigs without equipment, other than some large
plastic containers with covers (about the 2 gal. size), some deflocculent
(sodium silicate, Darvan 7, etc.). The basic approach is to measure out the
water (preferably distilled), add the clay, let it rest a day, mix, then add
the defloc. & let it sit a few days before discarding the top H2O & siphoning
off the t/s. Some people let it rest about 20-30, min., then decant to
another container, leaving the sludge behind, then repeating this every 20-30
minutes, for most of the day, or until there's no sludge.
I have about two dozen recipes gathered from various sources, and will e-mail
them to you if you'd like them. There's too much post on Clayart, so e-mail
me directly.
Good luck!

I have almost stopped using terra sig.. in favor of a mix. This mix is 75%
epk, and 25% soda ash. Mix it thin like skim milk....apply a coat and
burnish with a soft cloth.. then proceed until you have three coats..each
shined (burnished) . I have found that this takes color better than terra
sig.. doesnt chip off, and is a heck of lot easier the mix....oh yes,. i
fire mine to cone 06.........
Anyone else tried this yet..?

Hi Jim: What percentage of colorants do you add? Do you ever fire this mix
to cone 04? What does it look like if you don't burnish it? What does it
look like if you put clear glaze over it?
Thanks,
