Can you build wax wire? even if uneven?
I had a go this afternoon, it took a bit of time to get the
temperature right but yes, you build up a pile of round top meltings
of wax and then run the end of the tool up the sides to smooth it
off. It was a bit uneven I could do with a lot more practice. It was
0.5 mm wide and 10mm long, a few minutes work, I suppose I would get
faster. If I had to do a lot I would extrude some with a glue gun,
turn down the power and use matt extruding wax, weld the bits in
The thing I like is that I am working in the same wax as the model,
in this case green carving wax, then when you recarve the surface is
not radically softer or different in texture. Also for example I made
a little umbrella model with little triangle for folded fabric 30mm
long, I could weld down inside the lengths of the sections with
little danger of melting bits I didn't want to. It is very useful for
filling in those odd air bubbles you always find just under the
surface in a crucial place.
I accept that doing it with a hot needle is I am sure more skilled,
I just think that for very small work heat control makes it easier. I
personally think that using a microscope makes the most difference,
just by letting you see what you are doing.
By the way I must credit Mr Mattiello in Jewelry Wax Carving with
the tip about the bit of thin wire to make a fine welding point, this
is a book that goes to the limit of hand carving skills.
