Adam Pennington on sat 3 feb 07
Hello fellow potters,
My name is Adam Pennington in Florida, and I saw from
reading some of these forums that some of you have had
knowledge on englobes and/or once firing. I've got a
quick question for anyone out there who has
successfully once-fired raku (I'm trying crackle
and/or copper finish glazes).
Basically, I'm wanting to throw some pots, and while
they are still wet, glaze them with an englobe or
straight glaze (if possible), and then slowly fire
them in a bisque-like manner.
So, My theory is that I'll be able to load them wet
and glazed, but candle or preheat them for a couple of
hours to dry them out. Then I'll slowly take them up
to 1900 degrees just like any other bisque load.
However, since this is raku, I'll pull them out on the
way down at about 700-900F and then do the raku
process to them.
I know this is "far out", but I'm sure someone knows
how to do this or has a clue. Please reply if you
know anything about this.
Any help is appreciated.
Thanks!
Adam

Hardly 'far out'. In fact, except for
the 'loading wet' part, some people do
this routinely, especially those who do
their raku in a standard electric kiln
which won't go a lot faster anyway. Aside
from the modest energy waste of firing
wet stuff instead of waiting, there's no
real reason not to do it this way. I'd
be careful of your glazes, though. Make
sure they can handle the bisque temperature
without running all over. You are limiting
your glaze choice to those that can do
both (standard low-fire temp, AND raku)
well.

Some many years ago, I published an article called: Total Wet Firing. I
would take a freshly thrown pot off the wheel head and fire it immediately
in a preheated raku type kiln Did a workshop for a group of local art
teachers, so we were able to "experiment" this type of firning with more
than 100 pots so we were able to get all te wrinkels worked out. You might
call
the approach a one-upmanship raku technique. Allthough I still have one pot
on my shelves, it was great fun but not very peranent. The entire firning
proces took about 5 minuets!
If anywone would like to see how to do "Total Wet Firing", I'll put it on my
website as a free download.
