Hi Snail - 
It has not been my experience that terracotta earthenware bodies high in Redart develop a "pinkish" color.  I suppose it's all a matter of the recipe and firing temperature.  Here's Francine Ozereko's cone-04 terracotta recipe, which fires to a rich brick-red.  I posted this on Clayart just the other day in May of 1997.

Francine Ozereko's Terracotta - cone 04 - dense, fine-grain body for
functional work - fires rich brick-red - excellent for sgraffito, mishima,
slip layering, etc.  Don't overfire or it will blister internally.  
Redart ------------- 60
XX Sagger -------- 12 (or an additional 12 ball clay)
Ball Clay ---------- 12
Talc ---------------- 10
3124 Frit ---------- 6
Total ------------- 100

Diane, thanks for your extensive response!   I have been using a ^5 commercial throwing body for these little burnished objects, and it works well enough. I also have no basic objection to non-fired surfaces for non-foodware; I do this a lot. I just figured I should take a little more control over the medium if I was going to do this stuff more seriously, so I was looking for a starting recipe to tinker with. I doubt it will make a big difference, as I’ve done this successfully with whatever clay was lying around in all sorts of places. I might even try coloring some porcelain, just to try the option. The stakes are low, so I will probably just experiment a bit.
