Useful Tips For Budding Wireworks #2 Oxidising

The second in a short series of useful tips, this time ~ Oxidising Sterling Silver & Copper jewellery

Whether you oxidise your jewellery or not is a personal choice. I prefer the look of oxidised or "antiqued" Sterling Silver and copper wirework as it adds depth and highlights detail.

What you will need ~


Liver of Sulphur


You can buy Liver of Sulphur in liquid or solid form. I say "solid" but it's really powdery chucks. I prefer the solid form as it is more economical. I buy mine on eBay and it can also be found on jewellery supply sites.





Steel/Wire Wool

0000 or 00000 Grade which can be found in DIY stores






Oxidising your jewellery

Before you start, close the kitchen door and open the back door (wide!) Yes the clue is in the name Sulphur and it stinks like rotten eggs!
Dissolve a small piece of Liver of Sulphur in hot but not boiling water in a small bowl. I keep a bowl especially for oxidising. Avoid touching the Liver of Sulphur if you can help it, it doesn't sting if it comes into contact with your skin but does make your skin tingle for a short while. Always wash your hands if they come into conatct with the Liver of Sulphur. Use a spoon or old pair of flatnose pliers to handle the Liver of Sulphur or gloves if preferred.
Drop your jewellery into the bowl. Copper oxidises very quickly, Sterling Silver takes a bit longer.



Once the jewellery has turned black/grey remove using a spoon/pliers and rinse in a bowl of cold water. Allow to dry on a piece of kitchen roll.
When dry, polish with wire wool over a piece of kitchen roll. This can be quite time~consuming but very therapeutic!




When you've finished cleaning with the wirewool check for any stray bits of wire. How much you clean up your jewellery is up to you : some people leave it fairly black, I prefer it well polished. Finish by polishing to a shine with a silver polishing cloth, available from any supermarket.



The End Result

 Before


After


 The Liver of Sulphur solution can be kept and used again, preferably on the same day, if you heat it up in the microwave. Any longer than a few hours and it loses it's effect. It's advisable to dispose of the solution by tipping down the outside drain!

    Hello,

    Thanks to share your experience with LOS. I am really interested in because i use it a lot. Would you please let me know what you mean by "heat it up in the microwave", and "any longer than a few hours and it loses it's effect". Does it mean there is no more danger if you put it in the microwave after using ?
    Sorry but my english is not so good to understand subtilities...
    Love your wirework, just delicate and lovely.

My Jewellery Shed Gets A Lick Of Paint

At the end of last summer, after an incredibly busy few months jewellery-wise, I decided to take a break and repaint my shed. I'd painted it a pale green colour when I first got it and it was starting to look a bit faded and sad. So I did what I expect most people do and started looking online at what wonderful colour I could repaint it. There are lots of great colours out there by Cuprinol and Ronseal and the DIY stores own brands. I took a long time deciding on a colour then got in the car to go and buy the paint. That's when I discovered that B&Q and Homebase only carry a limited selection of shed paint colours {8 if you're lucky} and if you then find something in stock you do like they quite often don't have it in the size pot you need! So the colour I bought was a bit of "Oh buggar it, that'll have to do". Luckily it turned out to be similar to what I'd originally wanted by the time I'd finished the third coat - yes it took three coat...

Etching Copper With Ferric Chloride

 I decided recently that etching is one of my favourite things to do with metal. I read about it online quite a while ago and immediately thought it looked cool but the thought of using an "acid" and having to find somewhere to store it (a perennial problem when you don't have a workroom) put me off. So instead I admired etched copper from afar. Until I got a bee in my bonnet about it again and bought Lexi Erikson's copper etching dvd. Lexi Erikson is very good at explaining jewellery techniques and making them seem much more straightforward than they first appear. I already knew that ferric chloride was a salt and not an acid so wouldn't eat my flesh through to the bone if I accidently spilled some on my hand. The dvd made me feel much more comfortable about having a go so I ordered some ferric chloride from ebay and bought some stamps and StazOn ink from a local craft shop. My first attempt went ok but for some reason I left the copper to etch for an hou...

Amazing Enamel Effects

Buying a kiln recently has given me the chance to experiment with enamelling on larger pieces of copper and to produce some really cool effects. These effects happen when you combine different types of enamel. I usually use smaller flat pieces of copper for making enamelled earrings and have had some of these effects happen when firing with a torch but they are much more obvious when you use larger pieces. I made a few practice pieces which you can see in the photos below. This was flux {a transparent enamel not to be confused with soldering flux!} applied straight onto copper and fired until the copper was a bright golden colour. Then I added a layer of liquid enamel in green and red over the flux and fired again.  The lines and spots form when the enamel becomes hot enough to start moving and in this case the transparent pushes through the liquid enamel layer forming these cool lines and spots. The effect is better in the green liquid enamel than the red.  N...
