This is method of mixing wax, bees wax, with resins (maybe pine)
until the mixture becomes like taffy, then pulling the wax and
getting a texture on the surface called 'hikime'.
I am not familiar with the ‘hikime’ technique in particular, but I
think I can help you with the wax mixture. I studied lost wax
casting in Nepal and this sounds similar to the wax mixture we were
using. It was beeswax mixed with the resin of the sal tree (a local
pine). There is no indoor heating, so they mix it depending on the
season to get different melting temperatures. So the hardest
mixture would be a 1:1 ratio of wax to resin and a softer mixture
would be 1 part resin to 4 parts wax. A small amount of vegetable
oil is added, about 1 to 11/2 parts oil to 12 parts of the wax/
resin mixture. This wax is heated gently over smouldering soft
charcoal to work it. It is almost like modeling clay when heated,
then becomes hard and durable when cold. I haven’t devised a way to
heat it here in the US, but then again my only outdoor area is my
fire escape. I am sure you can come up with a way.
The mixture must be heated carefully at a very low heat. I think a
double boiler for a few hours would be the best strategy. In Nepal,
the mixture is heated over an open fire for half a day. The time is
reduced if the resin is pulverized before heating. I got a nasty
burn the first time I tried making it here on my gas stove, so I
must emphasize caution while making this mixture.
When I left Nepal, I brought a large burlap sack of this resin with
me. I would be willing to part with some of it, if you would like
some. Contact me off-list if you would like some of the resin.
Have a look at www.artnatasha.net to see some of the sculptures I
made using this traditional lost-wax technique. Also, I am happy to
announce that my jewelry website was launched this week
I hope I have been of help to you.
