Have you ever wanted to make your own silver wire jewellery but are struggling with the annealing process? Don’t worry, we’re here to help. We’ve created an annealing wire guide to help you understand how to anneal metal and how to begin.

What is annealing?

You may be wondering what is annealing and what does it do to metal? Annealing metal is the process of heating the substance to a specific temperature before it’s worked on. Through this annealing process, the precious meal is softened and made pliable. This will allow you to shape the metal into the jewellery piece you want. You might need to repeat the annealing process in case your metal work hardens.

What is work hardening when annealing metal?

Work hardening occurs when metal is repeatedly bent and shaped, putting stress on the metal and causing it to become more difficult to work with. The repeated stress on the metal can cause it to snap because the molecules can no longer absorb that amount of pressure. The effects of work hardening can be reversed through the process of annealing metal. This annealing treatment will soften the metal, making it easy to work with once again.

What is the annealing process?

When annealing metal, it will turn into an obviously darker colour followed by blackening. This is a chemical process known as oxidising. The annealing heat treatment process must be continued throughout oxidisation until the metal reaches a red colour. This cherry red colour occurs when the metal has reached a critical temperature. As soon as the metal reaches this point, heat must be removed from the precious metal, otherwise you run the risk of melting the alloy.

Then, the metal must then be placed in cold water. This is known as “quenching” and the colour will last for a few moments until the metal relaxes. The annealing metal process can be repeated several times with one piece of metal. There is no limit to how many times metal can be heated and manipulated. However, it is always best to anneal the metal as soon as you feel it start to harden. That way, you avoid causing irreversible damage to your piece.

It is not possible to predict the exact moment a metal needs annealing, and you will only learn the difference between a soft and hard state through practice. There are, however, a few basic tips that can help you.

Annealing wire, sheet metal, and varying alloys

  • Remove the protective plastic before annealing. This can sometimes be kept on when performing various piercing applications.
  • When buying sheet, always assume that it will need annealing.
  • It will be easier to decide whether 1mm round wire is soft, however it’s not as simple when working with a 5mm wire. Therefore, you should always begin annealing with a thicker wire.
  • Pure 999.9 silver and 24-carat gold do not oxidise as they are intrinsically soft. They will only need annealing if extensive work has been performed.
  • Perform your annealing with a soft flame by gently pushing the flame up the length of the metal, rather than waving it from side to side.
  • Ensure your metal is completely dry after quenching. This is essential as you do not want to rust the tools you work with. Also, check that your tools have no marks as they can be passed on to your metal.

How to anneal wire

Annealing thin wire

When annealing wire that is thinner, wrap it into a coil and tuck both ends back into the coil. This will prevent it from springing apart when heated. Place your coil on a soldering block and heat it wilth a soft flame, but keep moving the torch up the metal to avoid melting the wire. Turn the metal with a pair of insulated tweezers and anneal the coil on the other side.

Annealing thick wire

You will have to support the metal when heating and annealing wire that is thicker. Place the metal on the soldering block and use a soft flame until it turns red; then move along the wire to complete the process. Let the metal cool for a few seconds, then quench it in water.  Leave it until it has turned white and after removing it from the pickle, rinse and dry. Then you are ready to work!

How to anneal  silver sheet

  • To start creating the perfect silver wire jewellery pieces from silver sheet, cover your metal with a protective non-oxidising powder. Keep the powder away from your soldered joints to avoid making the solder run.
  • Remove the plastic coating from your silver wire and rub dry paper over both sides of your silver to remove the silver shine.
  • In a saucer, form a thick paste by mixing powder and methylated spirit or water. Add a little more spirit or water to make it easy to paint over both sides of your metal.
  • Place the silver sheet on a soldering block and heat it with a large soft flame. Like with wire, use the torch on your silver sheet until it has turned red and then move along the surface to complete.
  • After cooling the metal, place it in warm pickle for 5-10 minutes. This will remove the protective powder.

And there you have it! The very basics you need to know about how to anneal metal, the annealing metal process and how to create beautiful silver wire jewellery pieces.  If you’re looking for some more tips on how to create metal jewellery, then why not check out our silversmithing guides?
