Art Clay Bronze is a clay material to make a wide range of pieces such as jewelry, craft designs, and objects like sculptures and models. Art Clay Bronze must be fired in an activated carbon under reducing atmosphere using a programmable electric kiln, with the resulting fired piece being solid alloy (Copper 90%, Tin 10%).
Copper/Tin alloy ratio in Clay state : 90 % (Rest of 10% is Binder and Water)
Shrinkage: Approx.10%-13% in length
Firing schedule: Please see the details below.
Available package:50g (2 pieces of 25g)
Material form: Lump in aluminum package
Art Clay Bronze is a water-based clay, and dries naturally in the air. To avoid drying, when start molding your piece, only take out the needed amount to make your desired piece, and store well the rest of the clay using the instructions explained above. The shrinkage of Art Clay Bronze during firing is approximately 10%-13% in length, so please consider this when planning and making your piece.
Dry completely after molding. The dried clay will become hard like plaster, and you can easily enjoy the process of drilling, filing and sanding with hand tools and equipment. Follow the drying instructions and drying check method below.
Place the dried piece on a piece of stainless or glass plate while still warm. Leave for a couple of seconds, then remove your piece from the plate. If you do not see any vapor cloud on the plate where the piece was, drying is completed.
Drying guideline for drying a piece up to 1mm thick, 5g: *If the piece is larger than this size, drying will require more time.
| Way | Time/Temperature |
|---|---|
| Hot air dryer | More than 10 mins. *1 |
| Electric Hot Plate | More than 10 mins at 150°C/ 302°F |
| Electric Kiln | More than 10 mins at 150°C/ 302°F |
| Natural Air dry method | More than 24 hrs |
*1 : Place the piece as close as safely possible to the hot air while taking care not to drop the piece.
***DO NOT dry the piece over 250°C/482°F, or the binder will be destroyed during drying and deform the shape during the firing process.***
Art Clay Bronze must be fired in an activated carbon under reducing atmosphere using a programmable electric kiln.
As a character of alloy, oxide layer will be created on the surface. Have a surface polishing or use a solution made with pickling compound to remove oxide layer.
*After pickling, neutralize acid of the piece by dipping it in a baking soda mixed water (a small spoon of baking soda in a glass of water) for over 15 mins, then rinse well under running water.
*For use and proper disposal of the pickling solution, please be environmentally responsible and carefully follow the instructions of the pickling compound product.
After firing, the piece shows matte surface luster. Using metal wire brush, file, rotary tools, buff polishing will give beautiful metal luster. *When finished bronze exposed in the air, color will be changed as oxidation proceeds. The metal luster can be regained by polishing.
