The Making of a Bronze Pendant with FastFire BRONZclay

Making a Bronze Amulet -Thor's Hammer -

If you ever wondered how I make all those metal clay pendants, here is a short description of  the Thor's Hammer amulet with a gemstone setting. I have taken some pictures during the process. It actually takes 2 -3 days to finish the product.

Well first I sculptured with FastFire Bronzclay the basic form, after the first drying I made with bezel wire the setting for the gemstone and carvings. Some parts are added with a syringe of bronze clay paste. After that step it has to dry again - I use candle warmer to speed up the drying process.

Once the pendant is bone dry, I start sanding it to make it nice and smooth. After sanding and refining the pendant I let it air-dry for about 12-24 hours to make 100% sure that it is thoroughly dry before firing the clay in the kiln, otherwise if moisture is still trapped inside, it could cause cracks during the firing process.

When complete dry the pendant is ready to be kiln fired.  The bronze clay pendant has to be fired in a stainless steel pan with a lid in layers of activated coal carbon (or coconut shell carbon) to prevent oxidation.  Depending on thickness of the clay, the FASTfire BRONZclay pendant get fired with 1550 F for 1-2 hours. (Original BRONZclay  fires 9 hours !!!!!)

After firing and cooling down time, I boil the pendant in pickle to remove all fire scale particles from the bronze.  I use citric acid solution with water as it is environment friendly and not toxic.

Almost, done, now the bronze get its final finish, polishing with the Dremel, and setting the rainbow moonstone in the pendant. The stone must be set afterwards as it can not resist those high temperatures.

Bronze Metal Clay is an environmental friendly green product. Bronze Metal Clay is a medium consisting of very small particles of the metal bronze, mixed with an organic binder and water for use in making jewelry, beads, and small sculptures.

After drying, carving and sanding the bronze clay will be fired with approx. 1550 degrees Fahrenheit  in a kiln. The binder burns away, leaving the sintered solid pure bronze.
