I checked the archives for on making a steam de-waxer,
and learned quite a bit. However, I still have some questions.
Someone mentioned the possibility of using an inexpensive electric
roaster as a means of dewaxing, but there was no as to
whether to use it dry (as a regular roasting oven), or to put the
flasks on a rack above some water and use it as a steamer. Also,
would one be able to generate enough heat to melt carving waxesi.
Someone else mentioned that one could rust out their kiln if the
flasks were put in directly after steam de-waxing. If this is the
case, how long should one wait before puting steam de-waxed flasks
into a kiln i. Other suggestions were using large pans with racks to
keep the flasks elevated above the water, and to steam for an hour.
However, the problem would be that there would not be enough heat to
melt carving waxes.
Several mentioned the use of a pressure cooker, which seem to me to
be ideal as it creates steam hot enought to melt carving waxes.
However, the pressure cookers that I saw, seemed very large, heavy
and expensive. Are there any alternatives to them.
If a pressure cooker is the most feasible way to go, what pressure
should one use, and how long should one steam the flasks.
