Having used an electric kiln for the past 12 years, I would now like to see
the effects of reduction firing on my work.....
What are the possibilities of building a small test kiln for such
firings......and ideally one that's not too complicated and easy to
fire......
I usually fire to 1180c, but I believe it has to be higher with reduction
firing....I think....
Thank you in advance for any help and advice.....

Seems like I knew a story about a young man from Kent, but that's another
story. You asked about reduction test kiln on same day someone asked about
electric test kiln. I didn't see a response addressing reduction so you may
find some help on subject at this site
http://www.digitalfire.com/education/firing/index.html
My experience is parallel with advice from John Hesselberth (msg #100943).
The small kiln will go up and come down rapidly producing results far
different from slower firing/cooling large kiln on the same glaze. If one
adds propane gas as a reducing agent test glazes will be greatly affected by
amount of reduction, duration, and starting temperature of body reduction.
If you look in the archives using gas/electric thread you will find
considerable info. I'm presently in process of gas/electric modification.
Good luck!

In Leach's Potter's Book he has a DESIGN for a small test kiln fired with
a blowtorch which is a brass can with a little pump build in (on same
principle as soap dispensing pumps) and had a nozzle through which one
blew kerosene which, ignited, sent out a long flame. A bunsen burner
should do the same, I expect.
