dear Harvey;
Thanks for the clarity! I will add this to my vocabulary.

Hank and others,
In response to the several private posts asking me what "steaming
reduction" means, I thought I would just reply to everyone at once.
Streaming reduction is a reduction which is achieved by creating a long
loopy flame, which circulates throughout the kiln. I achieve this in my
kilns by closing the primary air control on the burners until I see some
visible smoke coming out the chimney and/or the spyholes. (My
experience is that billowing smoke is really not necessary and often
hampers proper body reduction and glaze reduction effects. A little bit
of smoke goes a long way.) Then I check the bottom spyhole and can
usually see a clearly visible flame pattern running around and in
between the pots. This works best if the damper is left open. On my 40
cu.ft. reverse draft car kiln that means 3 or 4" of damper opening.
For shinos, 2-3" encourages the blacker carbon trap effects and 4" makes
for brighter colors (white to orange).
