Work hardening in jewellery making, is the process of changing the temper of the wire to make the wire stonger.
Metal jewellery wire comes in a range of hardness - soft, half hard and hard. When using soft wire for example, you will find that it is really easy to bend out of shape which means you need to work harden it is withstand your chosen design and ensure it doesn't lose its shape.
Although it's not really necessary for wire wrapping techniques, you can undo work hardening by the process of annealing. This is heating the wire to a certain temperature which will soften it and make it malleable again.
Yes! Be aware that work hardening metal wire too much can make it brittle and can cause it to snap. Always keep testing your wire during the process of work hardening to ensure it isn't being worked on more than necessary. If you find that the wire is on the edge of breaking, you can anneal it to avoid this from happening.
This depends on your chosen design however if you can, it's recommended to start work hardening before creating your design. Be careful if you are work hardening later on, especially if you have added gemstones as you don't want to risk damaging them.
You can work harden most jewellery making wire including silver, brass, copper and gold. We would recommend doing some research if you plan on using another metal before going ahead.

Nylon jaw pliers are an essential for all jewellers working with wire. Not only are they great as they don't mark or scratch your work, they can also be used to work harden your wire - and to straighten it too!
Simply pull the wire through the jaws multiple times until the wire feels stiff. They are also great for squeezing over finished pieces of jewellery to add that extra strength.
These professional quality pliers by Beadsmith have double nylon jaws - great for opening and closing large jump rings or when using wire wrapping techniques. These pliers are particularly useful to straighten out wire too. They are a box jointed construction for ease of use and the nylon jaws can easily be replaced when necessary.
This is another simple and quick way to work harden your metal before using it. Use flat nose or snipe nose pliers to hold the wire between the tips of the pliers, hold tight and twist until it hardens. We love using this technique before creating gemstone bead bar necklaces, especially on 0.3mm wire which is quite thin and could easily lose its shape.
You will find a range of high quality jewellery making pliers and wire cutters on our website, for all your jewellery making needs.
This technique is great for using on pieces like earwires and hoops to strengthen them.
All you need to do is place your piece onto the steel block and use a hammer to gently tap the piece until it hardens.
A rawhide mallet is great to use as it won't damage your work, a chasing hammer on the other hand will flatten your work slightly as well as harden it.
You can also use the rounded end of a chasing hammer to create a gorgeous hammered textured effect, which will also harden it in the process.
Use a steel block to hammer and form metal on - perfect for both wireworkers and metalsmiths.
Use a rawhide mallet for shaping and forming metal without leaving any hammer marks!
If you have multiple pieces of jewellery that need work hardening, you can use a barrelling machine!
It's best to work harden your jewellery before working on it, however popping them into a barrelling machine will harden the outer layer of the metal and make it stronger.
The machine works by 'tumbling' stainless steel shot around in the spinning vaned or paddled barrel which impacts on your jewellery acting like thousands of tiny hammers planishing the surface of the metal, polishing it to a high shine.
Using the barreling machine for a final polish & to gently work harden your designs. It is perfect for the polishing silver (all types including sterling silver and fine silver as well as tarnish-resistant silver), gold, copper, bronze, palladium, platinum and all metal clays.
