My experience on the subject of Raku Reduction is that leaving the work in
the reduction material is the best. Getting the right amount of reduction
material is important. There needs to be a good flash of flame to give you
the colour you want from the glaze. The range of colour variation is
large and thus it can be frustrating finding the right amount. Too much
will keep the peice too hot for too long and you will get the oxidized
result. Too little and you don't get the "flash" that I like. I like to
see the some what photographic record of the flame traveling over the
surface of the piece.
Another aspect of this process is the presence of water. Having a bit of
moisture available for the piece to create steam will not only cool the
piece but add to the reduction enviroment. It does this I believe by
filling the reduction chamber with hydrogen. The moisture in my process
comes from some damp straw mixed with a larger amount of dry. When the
piece is placed in the reduction chamber enough dry straw to cover the
piece is placed on top. Once there is a flame which is fairly
instantanious the lid is placed on loosely for 10 seconds then it is
sealed.
Good luck!
