I have always been curious about ideas like this as well. There has
to bea more efficient way to cast wax models than firing up a 2000
watt burn outoven for hours. I also believe there must be a way to
simplify even steam casting where again, because of the idea that
you must get rid of all the moisture in the investment and to keep
the flask hot enough to avoid freezing the pour, it is recommended
to cast at a very high temperature. (this canbe done on an old hot
plate for cooking but only the vintage hot plates have the right
coils that conduct so well).
I started out just two years ago making jewelry as a hobby and have
been using the delft clay sand casting methods and have been very
pleased with the results. No pre heating is required. But of course
you cannot produce undercuts and there is more finishing work.
However, with planning you can make items in pieces to achieve
I found a vintage mint condition hot plate and plan on trying steam
casting in order to try better castings. So perhaps I would suggest
that method since you can burn out wax and pre heat the flask with
Has anyone found an even less energy involving method of casting
from wax models?
