Pottery Tips and TechniquesFiring Copper Matte |

 When firing copper matt, it is not the glaze recipe as much as how it is reduced that will give you those beautiful colors. A lot of people go to extensive lengths to get those purples on a consistent basis by using oxygen and alcohol after the firing process. What I have found most helpful without going to the oxygen and alcohol method, is to fire the piece up to 1800 F. to adhere the glaze and then let it cool to around 800˚ F. Fire up again to 1100˚ F and then with gloves or thongs put the pottery or ceramic in a metal garbage can filled with newspaper. When you put the piece into the can, you want it to just ignite the paper. You will notice that while the pottery or ceramic is hotter, the flashing will move quickly. You should wait till the flashing has slowed, then clamp on the lid until the side of the can cools. Now, if you don't get what you like, just refire your pottery or ceramic. There is one bad side to this glaze method, which is that it will fade with time, and more so in direct sunlight. To get the copper matt, add this to your basic glaze recipe: 400mg copper carbonate 400 mg copper oxide 200 mg Ferro 3110 Mix this glaze in smaller quantities because it does not store for long periods of time very well.  You can get this by adding barium to the recipe above. I don't use this very much because of the fact that it fades with time, no matter what you do to protect it.  I think one should fire a piece of pottery or ceramic with this glaze at least once to experience the thrill of seeing what you get!!! It's just like opening a present on Christmas morning.

All About Clay The best way of starting out is to take a few lessons. You will probably waste quite a bit in materials when you first get started. Figuring out how to truly make handmade pottery correctly and shape into what you want it to be can be quite an ordeal. The different tools that a normal shop will have can be fun to try. You will soon see which ones you like to use the most and then when you are ready you will know which ones to buy. When you get all set up, just enjoy the
hobby and have fun at it. Some people get pretty
serious and start selling their creations at craft
fairs and small stores, but others just like
to create items for themselves, relatives, and
friends. Whichever kind of handmade pottery you
desire to endeavor, enjoy the hobby and have
fun doing it. |
