I think you should not ask more of the wax than either you or the wax
is capable of. An example might be trying to make a complex single
wax when maybe a two component set might be better.
I have some trouble seeing symmetry and precise contour in wax. Ex,
a simple dome ring. Should be easy right, just keep cutting evenly?
Three file strokes this way, three strokes that way etc etc. Except
once its cast and polished even a small asymmetry is apparent because
now the surface is shiny. In a case like this I’ll make the wax to
allow for significant adjustments after casting. If its a one off
then I’m done. If I need a production mold I cast it in sterling,
refine to my heart’s content, then mold that. You need to allow for
shrinkage but depending on the design it may or may not be a big
So basically I DON’T make a perfect wax. I make a wax good enough for
the next stage. If my job was just carving waxes 40 hrs a week, this
wouldn’t cut it though. Mea culpa, but sane at 5 o’clock.
