Softening Copper Wire for Bonsai Use
Every year, at this time, I prepare my copper wire for use in the coming year. I buy 'annealed' copper wire but it is never soft enough so I go through the annealing process myself, in Winter when it is safe, and cold enough, to sit around a fire. I have always heated the prepared coils to a 'dull red' and quenched the coils in water. Quenching in water is not necessary for the softening process but helps blow off some of the oxide that forms during annealing; giving the wire a really natural look that blends well with the bonsai.
I generally use 1.22mm, 1.63mm, 2mm, and 4.1mm copper on my bonsai. After softening even the 4.1mm wire is easy to apply. !!

The Australian Bonsai Gallery has very few High End bondai left for sale. 
The Japanese Maple in this clip was purchased from The Koreshoff Bonsai Nursery in 1977. It was only a basic nursery stock plant back then but the Autumn colour was very good. It has been re-worked to improve the basic branch structure and to facilitate future ramification.
At the risk of repeating myself, I like to wire and shape my deciduous bonsai in early Winter. The branches are bare and it is easier to make design changes. Branches are still pliable enough to make significant bends.
Time to work on refinement of our deciduous bonsai.
