   Jay, I'm sorry I didn't post why I do my own wire. I'm cheap. Very cheap.

M. Frary that is the best reason possible, what temperature do you heat the copper at to anneal it? I will be trying this in the near future and really am just wondering if the best temperature deviates from what is posted in the normal internet research material.

  My hands have protested the use of Stone Lantern's copper.  If you buy it or already have some, I suggest reannealing it especially for the larger diameter sizes.   


Sorry Owen :-[ :-[ :'(  
I did buy a bunch of Gremel copper wire, and it is the stuff for sure.  Live and learn....
As far as alum, I used to buy from the monks, but they don't do online anymore.  There's an ebay store that sells pots and wire called Oriental arts and furniture that has good alum.  I got my last batch from Stone Lantern, didn't get the more expensive kind, but the regular quality is ok.  Maybe I'll try the Yoshi type next time and see what the difference is from the Bonsai Aesthetics wire. The aesthetics seems to lighten up in color somewhat after a while on the tree.


Judy, it definitely was not just you  :).  It's popular in Florida and the rest of the South as well.

  Joshua, I don't know the temp except that I cook it right open flames till the insulation is gone. The wire turns out nice and pliable.

Cheap is cheap. Don't stand too close and inhale the fumes off of the insulation. The goal is to get the wire to glow a dull red. The problem with doi nut this way is that you tend to get over hot and under hot spots, especially on larger wire. Those who do it well use a very uniform heating source. Also, removing insulation prior to annealing leads to more uniform product. I still gave kilos of badly annealed wire, that seemed ok until I got my hands on well done wire.

Then there is the term cost effective.  Damaging a good tree because of discontinuous annealing can be an expensive proposition. If you don't have trees of good/high quality, experimenting with wire may be a reasonable exercise. One of the reasons people say that using copper wire is so much more difficult is that all annealed copper wire is not the same.

I hope there is another Jim Gremel in development out there, we could always use another source.

John,

you are also allowed to use a small kiln / test kiln and just set the temperature, leaving the copper coil in for as long as it needs and it will be evenly heated.
Good Day
Anthony

Anthony, absolutely, using a kiln and understanding the  heat required is a key step.

I have some copper wire I have been given. Next I would like to heat it up in my barby to anneal it so I can use it for my trees. Does anyone know what temp and how long I should heat it for. My barby can heat way up there with the lid down so I want to do this right. Help.

Brian.... I don't know the temp BUT.....Warning do not use your barby that you use for food. This is not something you can have for dual use. This is especially true if you are burning off the insulation!!

My quick Google search suggests 700-1200ºF or 900-1400ºF.  Brent @ Evergreen Gardenworks says "Generally annealing is done at greater than 1/2 of the melting point on the absolute temperature scale."  Google suggests that the melting point of Copper is 1,984°F (1,085°C).  Most sources comment that the Copper will exhibit a dull red glow, ...so you'll know when its hot enough.
