What is Copper?

Check out my new Blog post  What is Copper?

I am now also blogging at my other sites, here’s the beginning of the post. Please check the above link for the rest of the article! You’ll learn about history of copper, its properties, uses, with samples of art and jewelry.

Copper is an essential mineral found in plant life and in the human body and it is also a metal alloy with a reddish-orange color. The use of copper dates back over 10,000 years. Pure copper is very soft and malleable and is combined with other metals, such as brass and bronze, for use in jewelry and other uses. Copper is used in currency (the U.S. penny), and is used as a heat conductor, in medical instruments, and has been used as a decorative coating of famous gates, such as the Temple of Jerusalem, sculptures, and statues, most notably, The Statue of Liberty, the largest copper statue in the world.

Since 100% of copper can be recycled without any loss of its original mined quality, it is the third most recycled metal. Over 80% of the copper mined since it was discovered thousands of years ago is still in use today. When copper tarnishes, a beautiful green patina covers the piece… Read more

Coin Impressed Creations – Coin Hammered Jewelry

Belgian Coin Copper Earring

This one is the Belgian Franc, Belgique!

I have been hammering lots and lots of coins recently! I was lucky to have someone in Europe mail me a ton of coins, in addition to the ones I had from Finland, Ireland and Estonia. Now I have a whole collection from Switzerland to Greece and UK. The creation of these poppies is a time consuming process and results are not guaranteed…but, I just like to play with this idea. Have been using both copper and brass as the base metal, using my disc cutter has been a bit of a challenge since it’s not the best kind (things get stuck a lot), but you learn patience 🙂

Etching Experiments

There are so many techniques to try when it comes to making copper jewelry. I just had to try etching. It requires the use of some chemicals, although I am learning there might be ways to etch using some more natural ingredients. (Hopefully, more on that later.)

You can buy these etching kits which makes trying it very easy. You get a pan to put your etching liquid (ferric chloride is the chemical), foam thingies to float your copper and the required electrical current gadget. All you need is a piece of copper and rubber gloves. You are supposed to use distilled water, I used Brita water and was just fine (tap water that has been put through a filter that removes impurities).

There are many ways to produce the picture you want to etch on copper. I used an oil based marker and just drew the picture. Some other etching hobbyists use things like ink transfers (from laser printer), Staz-on ink, lettering systems, even UV film.

The etching kit – pan, ferric chloride, foamies, wire and the gadget you plug in.

So, I had my picture drawn on a very well cleaned piece of copper. I mixed my etching granules with the water and let it dissolve. You then have to cover the back side of your copper with tape so it doesn’t etch, attach the etching gadget wire on the back of your copper piece under the tape, and insert these foam pads on the sides so it can float and doesn’t fall on the bottom of your pan. Submerge the item in the etching liquid, turn the power on and wait.

I let mine etch for a couple of hours, I realize it was way too long! The time depends on the size of the piece, or the depth of etching you want. Many patterns you don’t need to etch very deep. A good thing also is that you can reuse the solution. Eventually it will lose its power, but it should last for many etchings. Just please remember to take your used etching liquid to a hazardous waste facility when you’re done, no hurting of fishes allowed! Now I just want to figure out a way to do this with some natural non-toxic materials!
