Thanks for all the responses to my first question. Here's another one:
I've been told that it's hard to get a good shino with this kiln. Has
anyone had any luck? If so, what's your secret? Thanks---Lori

Dear Lori,
We have had an Olsen 36 kit for 12 years, rebuilt it a couple of times (after
someone fired metal bearing sculpture and it ate away at it...but that's
another story..)
Ist of all: when the kit arrives, from several separate sources, bricks one
place, frame another, burners etc. The frame is already welded and delivered
whole. We had to cut a path thru the alley and the back of the shop to get it
in. But we like it. It gives copper reds and celadon, usually.
2ndly: Firing updrafts are fun. You get to see the flame, and make your
adjustments by flame color, as well as back pressure, haze, etc. As long as
there is some back pressure from the bottom peep after body reduction (Cone
014 for 1 hr) and all the way up to cone 10, you'll get the shino. Of course
shino is best on an iron bearing clay (or a clay with red art slip on it) and
one dip of a fresh batch of shino. It is white if thick. The soda ash in it
changes after 24 hrs. Test everything.
Good luck. Bonita in San Francisco, eagerly anticipating the unloading of
the Napa anagama on Saturday. We fired for 6 days!! Full moon and flame. It
was great. Now the dragon sleeps, its gifts to be revealed. Soon.
