ART CLAY BRONZE 50GR

Art Clay Bronze is the new metal clay of Art Clay brand. It can be modeled like a plasticine, after firing it will allow to obtain a bronze piece (90% copper - 10% tin).

Instructions for Use:

Modeling

• Art Clay Bronze can be modeled like plasticine or clay.
• Containing water, the clay tends to dry in the air, it is therefore important that unused pasta is carefully sealed and stored properly.
• After firing the piece will have a shrinkage of about 10-13%, it is therefore good that this detail is taken into account during modeling.

Drying

• After modeling, the piece will be completely dried.
• Once dry, the piece will have a plaster-like consistency, so it can be drilled, filed and finished with various types of tools.
• For drying, we recommend using a hairdryer (10 - 15 minutes), a heating plate (10 minutes x 150 ° C), the electric kiln (10 minutes x 150 ° C) or simply leave it in the air (+24 hours)

Firing

• Art Clay Bronze must be fired in an electric kiln inside a steel container and immersed in activated carbon.
• The piece will be placed in the container making sure that there is at least 1 cm of charcoal on the bottom and at least 2 cm of charcoal above the piece.
• The container will be placed in the oven at room temperature.
• Carry out an upward ramp at 820 ° C.
• Reached 820 ° C, carry out a maintenance for 2 hours.
• Remove the container from the oven and allow to cool to room temperature.

Post-firing

• After firing, the piece will have an oxidized layer.
• To remove the oxidation it will be necessary to clean with rotary tools or alternatively use a pickling solution.
• After using the pickling agent, we recommend neutralizing the acid by immersing the piece in water with a spoonful of baking soda for 15 minutes.
• After 15 minutes, rinse the piece under running water.

Polishing

• The piece will have a Matt finish.
• To obtain the polished piece, treat it like any other bronze jewel, using brushes and polishing pastes.
