Make copper round-ended head pins?

Jewelry copper | metal I'm a totally self-taught metal-smith and need an assist. I'm trying to form my own headpins in copper. I'd like to get the end of a 24 or 22 guage copper wire to roll into a small ball. I am presently thouroughly cleaning the wire, applying flux (tried both borate-based and liquid from Rio Grand), then heating with a propone torch. None of my many permutations of flux and heat seem to work. Can someone walk me through the steps and clarify the temperature I'm shooting for (pre- or post-anneal)? Thanks! ![]() Copper oxidizes fast and

Copper oxidizes fast and that is why a paste flux will work better for you than the liquids. Silver is much easier to do this with and the new Argentium silver is even easier. Practice helps. Can you melt the tip of the wire when it is laying flat and you are not trying to ball up the end? If you find this temperature than it might be easier for you to adjust that to just balling up the end. marilyn » reply another approach

Warren, I've actually blown/melted holes through the sheet with my propane torch, so I think that means yes. I did fiddle with the oxygen to gas ratio and this, plus advise from others seems to have solved my difficulty. Thanks for taking the time! » reply success!

Take the wire to heat, not heat to the wire. Brilliant! I've successfully made 10 pins with this technique tonight. Thanks so much to all. It is amazing how some expert advise can really make a difference. Now...if I could just stop blowing a hole through my copper sheet when soldering with hard solder, I'd be golden. :) » reply ![]() You need to heat the whole

You need to heat the whole sheet for the solder to melt. Keep the flame moving. Put the torch in your non dominate hand and put it on "automatic" This way, your other hand is free to manipulate solder bits and parts. marilyn » reply |

copper headpins
Hi Mistyannemarold,
I'm not sure where you are having a problem. I use 'Handy Flux' (paste). After applying flux, you should place the wire about an inch from the 'blue' part of your flame & move or twirl the wire around until it forms a ball. Also, you might want to try using a charcoal block. I use an acetylene & air set up which burns a little hotter than propane & air.
