Question Glass & Copper Wire....

Anyone ever successfully put 104 on copper wire - cause I have two questions.

1. Melting temps of copper are around 1900 degrees, did you have any issues with it softening and bending?

2. What gauge wire did you use, and what length did you have to use to be able to handle it since copper is an excellent heat conductor?


I want to put glass ON a wire that is thick enough to hold shape, but small enough that I can bend it after annealing, and have the glass stay there. So basically, working without bead release.

I've made a bunch of glass headpins directly on copper wire. I tend to use mostly 18 and 20 gauge but I have used 16. I've had no issues with the glass coming off of the copper. The copper is nice and soft after annealing.

Edited to say: just briefly warm the end of the wire in the flame and apply the glass to the wire (keep the wire out of the flame while applying the glass).

Chris, I make flowers on copper wire. I use 18 gauge but can use 20 in a pinch. Just like MaryBeth said, warm your wire a little so the glass will stick. I use about a three inch piece and use a hemostat to hold the wire. After I anneal the copper wire is black, but a little scrubbing with Comet or Bon Ami makes the wire shiny again. It is very easy to make a loop in the wire.

Good luck!
Helene

20 gauge wire will melt in the flame quite quickly. Keep the flame on the glass, barely flash the wire to pre-warm it.

I use a pin vise from Arrow Springs to hold it.

You can pickle the wire to remove fire scale after your piece comes out of the kiln.

Christopher, I don't know what gauge this is, 20ga or heavier though I think. I haven't tried it on thinner, I was just playing with my new leaf masher. I used a piece about six inches long I think, then just wrapped the rest. I did use it in a short holder from Agate58 (is that right?), didn't have a pin vice handy.


I used a piece of 0000 steel wool to clean the wire off before I wrapped it.

Most of my work is headpins made on copper wire. I have gone as fine as 24 gauge for some projects but mostly use 22 gauge. As already mentioned, I use a pin vise to hold the wire, and just flash the tip in the flame. You can also precut your glass rod ( I use about a half inch), soften the glass in the flame and plunge the heated wire into it, rather than wrapping the glass on the wire.

24 gauge works fine, but you'll need to clean the scale off afterwards:

Many of us have make Bell Flowers on cooper wire and many images are posted on a variety of Bell Flower threads using mostly cooper wire or German silver wire. Here is one of the thread: http://www.lampworketc.com/forums/sh...ht=bell+flower
