Read Vince's terra sig article at the http://www.digitalfire.com web page.
It's under instruction or education or something like that.
In this article, Vince says you can make terra sig from porcelain or EPK or
some-such, but you'll get a low yield. He suggests ball milling, if you can,
to increase the useable output.

I'm trying to make a terra sig for Hutchens raku body that
will take flashing well, will be white and will fit well. I've made one
from the hutchens body and its light salmon coloured and I've also made one
from om4 and its not white enough? I'm thinking of trying to make one from
grollleg kaolin. Any help or ideas would be greatly appreciated.

Bryan is suggesting using Kaolin for terra sig.
I do not use kaolin, but I thought it was rather coarse grained, and
therefore is not a substance to use for terra sig.
So far I have only used the fine grained red earthenware clay which is my
But, I hope to experiment with Montmorillonite, (Fullers Earth, or Cat
Litter) as well as with a white earthenware clay which is my normal slip.
Use Vince's method of how prepare this wonderful substance. It takes some
time, but is worth it.
I use it on mug bottoms and the lower parts of most ware, so that the future
owner has a really smooth surface to hold and can be assured that polished
table tops will remain unmarked.

Try adding some Titanium Dioxide to your TS to make it really white. About 1
Tbsp/Cup. Suggestion from Pete Pinnell workshop in Houston last autumn.

Hi there, Brian
We use XX sagger. It comes out fairly white. It is whiter than om4 but not 'dead
white'. I was also thinking of trying porcelain in the sig. I'll let you know if
I get there first....

Martin, This is very user friendly of you to smooth your bottoms that well.
Too often one find coarse unfinished bottoms on peoples work or glazes that
are not fully matured and burn ones hands in the microwave etc. I had the
experience a month ago with someone elses mug in a microwave. I ended up with
a blister that went right through all skin. I got them two years ago from
someone before I could restart my own studio. Now I am ready to throw them
Good day to all of you.
