" Can anyone tell me about smokeless Raku? thanks Kathie"



The late Jerry Caplan gave workshops on "smokeless raku".

Plain and simple: A kiln shelf is placed on the ground, on top of the shelf
ONE single sheet of newspaper folded in half. The glowing pot is placed on
top of the newspaper and a garbage can is quickly reversed over the pot.
Sand seals the edge where the shelf meets garbage can and viola.....very
little smoke.

In my opinion, the results are just as good as the old fashioned method of
boiling choking smoke which stings the eyes and irritates the neighbors
within a mile radius.

Kathi, don't know there is anything that is "smokeless." But if you
really want to minimize the smoke just be sure to use as little reduction
material as possible for the results that you want and then, if you are
using cans for post firing reduction, place a coupla sheets of wet newspaper
across the top of the can before closing the lid. This will help to ensure a
nice tight seal of the can thereby eleminating much of an extended burn and
smoke. You may also place a piece of moist paper in the can which will
produce a bit of steam. This will help to create a bit of a positive
pressure within the can and will minimize the migration of oxygen from the
outside into the can after the can has been sealed. This will help if the
can leaks.
Another method is to build yourself a firing flask. Just make a pit of
sand and place some broken pieces of kiln shelf on the pit in such as manner
be far enough apart so that you can easily invert cans over the tops of the
shelves without contact.
After doing this make a small nest of your favortie type of reduction
material on each of the shelves. Place the pieces onto the shelves for a
quick burn and then invert cans over them as you need for whatever results
you are specifically after.
Once the cans are in place just push the sand up and around the base of
the cans. This pretty much gives you an air tight seal. This is probably the
method that is refered to as "smokeless." In reality there will be a certain
amount of smoke considering the fact that the ignition source of your
reduction material is the pot and there is a modicum of smouldering before a
flame is actually present.
Hope this helps
