Product Description
50gm Art Clay Copper Clay, a gorgeous warm-coloured and strong clay, with an extremely simple firing schedule.
Art Clay Copper only requires a 30-minute kiln firing time, and you don't need to use any activated carbon or firing pans - you can even fire it with a torch! It is an incredibly reliable clay, and the clay we recommend wholeheartedly to anyone new to base metal clay.
You shape and work with Art Clay Copper just like normal silver clay. You can mould it, press textures into it, stick dry pieces together, set stones in it; exactly as you would when working with silver clay. Art Clay Copper has a shrinkage rate of 8-10% which is similar to Art Clay Silvers 8-9%. Make sure any tools you use are clean of silver clay, as this would contaminate your copper, creating an alloy which doesn't take to firing very well at all. Use separate files and abrasive papers/sponges, as these are almost impossible to clean.
HOW TO USE
Kiln firing:
Put the dried clay on shelf paper on a kiln shelf, as the copper can stick to the shelf slightly. Place in a hot kiln and fire at 970C for at least 30 minutes. When finished, don't let the kiln cool down. You need to quench the piece immediately from hot. Keep a steel bowl just under the kiln door, and as soon as you open the door, tip the kiln shelf over so the piece/pieces drop into the water. Every second the piece is exposed to the cooler air, it will oxidise, which will damage the piece. The quenching will allow most of the oxidised layer which occurs during firing to peel off.
We also highly recommend firing under a thin layer of carbon - this makes the quenching a little less stressful, as the carbon layer will protect the copper and you can take a little longer moving it from the hot kiln to the quenching bowl. We literally poor a little carbon on top of the piece straight onto the shelf, so the piece is just covered with a couple of millimetres of carbon. This gets poured into the quenching bowl with the piece, but can then be sieved out, dried, and used again.
Torch firing:
You can torch fire smaller Art Clay copper pieces, keep them under 35gm, and ideally not much bigger than a 50p coin as anything bigger is impossible to keep evenly heated for the whole firing.
Place the piece on a firing brick and heat until cherry red (much hotter than silver needs) for at least 5-7 minutes, depending on size. Copper needs to be quenched immediately once you move the flame from it. This stops it from getting too much fire scale/oxidisation. Keep a bowl of water close to your firing brick and keep it so it is level or under the edge of the fibre brick; using long tweezers or tongs, either push the piece towards the water following it with the flame until it hits the water, or move the flame away and quickly pick up/push the piece into the water.
Storing Art Clay Copper:
The surface of Art Clay Copper will naturally start oxidising, and the colour will darken over time if left in the air. If you do get a darkened surface on your unfired clay - scrape most of the layer off, smoosh in any small dark pieces into the remaining clay. To avoid oxidisation of unused clay, wrap it in layers of cling film tightly, then place in a grip seal bag or airtight container. Our Art Clay Storage Pot is great for keeping your clay fresh and workable. Keep the clay indoors at a moderate room temp and out of direct sunlight.

Excellent
I have tried most of the copper clays and this is the only clay that doesn't give my work major firescale it just drops off with this clay, brilliant.

Best Copper Clay
This is the best copper clay out there in my opinion and I have tried a good few. I like it for the smoothness, the flex when dried in sheets for the silhouette, the small shrinkage and it seems easier to clean up after firing that some other clays. Unless I need a high shrinkage for some particular project I don't use any other brand anymore.

Great stuff
As a first time user a little trial and error on the torch firing, but very impressed.
-
Easy to work with!
This is the greatest copper clay i have worked with so far! It really doesn't need more than 30 mins at 970 to be fully sintered and beautiful! I'm really really pleased with this clay and will only use this copper clay from now on!

Smooth & Silky Clay
This is my preferred brand of copper clay for a number of reasons. I like that this clay can be torch or kiln fired AND as an added bonus, you can fire it on an open shelf in the kiln instead of in carbon. The clay is also very smooth to use, unlike others that can feel a bit gritty. The amount you get for the money means that this clay allows you to practise using metal clay if you're not confident to use the more expensive silver version without worrying if you mess up.

1st time user, very impressed!
Torch fired my first pieces made with this clay today, happy to say they turned out great. I don't have much experience with metal clay but this was so easy to work with from start to finish I will definitely be buying more in the future. Also, many thanks to the superb customer services team for answering my questions and helping me along the way.

Does what it says on the tin
The finished product is bright and light rather than the deeper red copper you get with other makes. It really does fire in the half hour and using carbon can help where there is detail for firescale to get caught in. A cold plunge directly out of the kiln deliver most firescale to the bottom of the water pot. We enamelled on ours and got very good results using the torch firing method.

The best copper clay on the market today!
After using several different makes of copper clay, I have found the Art clay copper to be by far the best. It is creamy in substance and very easy to mould and sculpt when making your desired piece. The only thing I more I could ask for is for there to be a 100gm packet of the clay as well as the 50gm x

Copper Metal Clay
Nice product, better than other Copper Metal Clays products I have used recently. Kiln fired in 30 minutes is a big plus as some are three hours and depends on how speedily you need the piece. I tried it two ways, one in air and the piece had some fire scale that all had to be removed. The rest I fired in activated carbon and a stainless steel box. This got the best results as no fire scale at all. Lovely product, beautiful result on the final pieces!

Working with ACC
Good product, easy to work with and longer working time than silver. Because it is very cost effective I often work a design in the copper before doing it in Silver, I find the best results are when its kiln fired. Lovely colour when polished.

Lovely to work with
Easy to work with, great addition to working with metal clay, stays wetter for a bit longer giving more working time to refine the project and best of all, at the price you can afford to be a little bit more experimental. Love it.
