We just used free dirt with a high clay content. We responded to ads
on Craigslist, and asked people offering dirt if they knew if it had
high clay or not, then if it sounded promising (or if they didn't
know), we'd go check it out.
Free fire brick is probably harder...we were lucky to have friends
who had recently relined their fireplace and had some left over.
Good luck!

Hi, Paul! Yes...we did something like what was described in that
book, and it seems to have worked well. It's pretty easy to tell
when you have a handful of wet clay because of its malleability (if
you can roll it into worms, you're in good shape).
For the final plaster, I had a potter friend with leftover 100% clay,
so we augmented the soil with that and mixed it with horse manure and
dryer lint for fiber, and that worked really well (except that there
must have been some undigested grain in the manure, because during
the first summer, the oven grew sprouts on it and looked like a Chia
pet :)

I looked, and can't find any. Too bad...it was pretty funny. After
they all sprouted the first season, they never came back.
Also: March 7th pizza party at Chateau Bagley, Wallingford
neighborhood, Seattle. Details coming soon.
