The studio I shared in college came equiped with an old ringer washer.
The previous renter had used it to recycle trimmings which were graddually
added to water and blunged when full.
I subsequently used it to mix clay.
Currently I use a drill motor and prop mixer but the washer was nice to tur=
n
on and walk away while it mixed

Many thanks to everyone for answering my plea.
Hank, I've come across Harry Davis' book from time to time over the years. =
Are the directions for your slurry system contained therein? Boy, do I have=
alot of questions! Maybe this is better done off list.
Paul, so glad to hear you've gotten good use out of that stoneware recipe. =
Mile Hi here in Denver doesn't supply C-1 anymore, so I've moved on with my=
testing. I'd be happy to share my latest white stoneware
recipe with you if you're in need.
Stephanie, thanks for straightening me out on the freeze/thaw test. I'm sur=
e you're correct. I'll take a more careful look.
