Bamboo karen here...I was the charcoal fire person...
Learned it at Pasadena City College...take a gas kiln...
turn the inside into a saggar...carve ports in the door...
load tumble stack with wads holding the work in place....
fire to cone 10...then throw in 200 pounds of mesquite charcoal...
have used the briquettes...goopy...petroleum product stuff...
prefer the mesquite.
The firings are better than woodfire...but that's my opinion.
Not as much work.
Turn your gas kiln back into a reduction kiln after...not much
damage to the kiln, tho. perhaps a little.

also regarding your question about So. Calif. groups...
I looked for a newsletter...and since I just moved I need to
dig deeper...But the Southern California Design Chapter of
the American Ceramic Society...has perhaps 4000 members...
ranging from the valley....San San Diego.
I will try to get you an address and phone...
