Peggy---
I have a Redart Terra Sig recipe that Ron Meyers supplied at his
workshop. I used it on bisque and it worked just as well as on
greenware. I did a large tureen during the workshop and it fired
beautifully. It's low fire. Don't have the recipe with me
today--however--will get it to you tomorrow. As I remember it, it's very
simple. What we used was ball-milled, but Ron said that wasn't
necessary.
We used a Standard red low-fire clay. Don't know the number.

Yes, a redart based sig recipe should "fit" a red low-fire clay....How
'bout a red sig recipe that'll fit white stoneware??

Hi Candice,
In response to your question , stoneware??>
Why not a Redart based sig on white stoneware? My limited (4years) experience
with sigillatas of various pedigrees indicates that the base clay is less
important than several other factors. Such as, Degree of refinement of the
sigillata, thickness of application, tooth of the surface that it is applied on
to, and the firing temperature.
I have fired redart based sig to cone five in reduction on a cone five base
clay. Sometimes it retains a tight satin surface and sometimes it "checks"
Firing it on bisque ware seems to lessen the problems and improve results at
those temperatures.
If you fire TS higher than cone 5, please let me know the results.
