I have been researching whether it is sound to mix waxes for casting
a piece using the lost wax method. For example to combine, in the
same piece, green wax wire and pink sheet wax in the making of a
flower. I would want to do this because I find the different types
of wax lend themselves to different types of structures, forms, etc.
The sheets lend themselves to petals, and the wax wire to stems or
other linear elements. The workflow of building a model all at once
really appeals to me.
People seem to say that this would cause problems during the casting
process due to waxes having different melting points. On the other
hand I have seen examples through online wanderings, of people who
do use waxes in this way. One thought I had was to coat the entire
piece, once finished with a thin layer of wax of one kind, though I
wouldn’t know which to use and whether this would solve the problem.
I have been told that wax combination models can be directly molded
rather than cast, but this would be inefficient for me given the
amount of work I do on a metal casting before I have a mold made. If
I go directly from wax to mold it will have to be molded again after
The only other solution I could think of would be to cast components
separately then assemble, or give to a contractor to assemble.
Any thoughts, advice, articles, or feedback would be appreciated.
Otherwise it will be trial and error which is costly and time
