PMC Books & Tools For Sale!

Just before Christmas I decided to have a go at making some jewellery with copper clay. This medium fascinates me - I love the scope it gives you in shape, texture and design

I'd read that it was possible to fire copper clay with a torch which was great as I don't have a kiln. The distinct lack of definitive firing times for copper clay using a torch should have made me think about it a bit more! The brand I used recommended at least 7 minutes for small pieces......................


I tried and tried with my propane/butane mix torch to sucessfully fire my small and not very thick pieces to a fully sintered stage - where the clay has changed structure and become 100% copper. Up to 15 minutes plus on most pieces and did it work? No it did not! Being used to working with sheet copper and feeling slightly suspicious of the look of the fired and cleaned up clay pieces, I took my pliers to them and managed to snap every single piece quite easily, revealing a very thin layer of copper around the outside with the centre still very much in it's clay form! So disappointing! The thin copper layer tricks you into thinking the torch firing worked - the piece sounds metallic when you drop it into the pickle pot and looks like copper when you clean it up but attempt to bend it with some pliers and watch it snap! I contacted the manufacturer asking for some guidelines on firing times and was basically told what I already knew - fire for a minimum of 7 minutes, no other info at all. Very helpful! Firing them for longer may have worked but pointing a torch at a small piece of clay for 20 minutes plus is not time-effective, not very good for your health and would frankly drive me insane!

And the moral of this? Don't believe what the manufacturers tell you about torch firing copper clay - in my humble opinion it does not work. Correctly firing it in a kiln is the way to go!

Hence the reason I'm selling my pmc books and tools! Available in my eBay shop

    Oh what a shame! I do know people who say the've torched fired copper clay successfully but I've never managed it either. I use a kiln and even with that base metal clay can still produce far more issues than silver. I have things working well now but it took a lot of testing. That said, your sheet metal work is beautiful so at least we'll see plenty more ofthat!

    Thanks Lesley! It is a shame it didn't work as I did enjoy the making side of it :D

    Keep your tools and try the silver clay, you can use a torch on these, or either try a butane gas torch rather than the propane as it gets hotter, this is mapp gas in the yellow bottle, i would try this before you give up.

    Don't give up on metal clay! You might get a kiln one day! I have never fired my pieces in a kiln, only torch fired them, but most of them are tiny, so they worked ok.

    Thanks! I did think about trying silver clay but the price is so high which puts me off.
    Will stick to sheet metal I think!

    I mentioned in an earlier comment that I love near to Eastbourne, and I do have kilns, if you ever wanted to use a bit of space in mine let me know.

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...

Combining Soldering And Enamel

The need to make cute, brightly coloured enamel studs propelled me into the world of combining soldering with enamel a couple of years ago. I knew from reading up on it that it was possible to enamel and solder on the same piece but wasn't too confident I was able to do it back then. It was a slightly embarrassing occurance that made me just get on with - I'd made some enamel studs with glued on stud posts. I'd used 2 part epoxy resin which was a job in itself as it set hard after 5 minutes so I had to keep mixing more up. The finished studs looked ok but that little voice in my head kept asking "are you sure you want to use glue?" I wasn't but didn't think I had any other way to do it so I used glue. I sold my first pair and merrily sent them on their way to Canada. A couple of week later the buyer got in touch to say the stud post had come off one of the earrings and the other was hanging off. I was mortified, apologized profusely and refunded her m...
