Goldie Sculptors Bronze Clay 50g

Goldie Sculptor’s Bronze™ is bronze of a beautiful golden color, which is very hard after firing.  It is formulated with long carbo-hydrogen chains in the binder formula to have much greater strength and more resistance to collapse under its own weight than regular bronze clays and is more cohesive when wet and stronger after the first firing step.  This allows the artist sculptor to create much larger designs.  Another aspect of Sculptor’s Bronze is its silky smooth texture and with appropriate hydration it can be thrown on a potter’s wheel.

Goldie Sculptor’s Bronze ™ is well suited for sculptures and larger forms of jewelry. You can shape the wet and dry clay using chisels and other traditional sculptor’s tools.

FIRING

This clay can be fired in electric kilns only.

● Lay the pieces in a stainless steel firing container on a layer of activated coconut shell carbon with a minimum depth 1/2” (1cm) under the pieces.  Do not cover with carbon for this step. Make sure the pieces are at least 1/2” (1cm) apart. Place the open container into a cold kiln and fire at full ramp to 670ºF (350°C) and hold for 30 minutes for pieces up to 100g.  Pieces larger than 100g hold for 45 minutes, larger than 200g – 45 minutes, larger than 200g – 1 hour, larger than 300g – 1.5 hours.

● Carefully remove the container from the kiln and place on a heatproof surface. Fill the container with a layer of activated coconut shell carbon with a minimum depth 1/2” (1cm) over the pieces and place back into the kiln. Do a full ramp to 1525ºF (830°C) and hold for 1 hour for pieces up to 100g. In the case of large elements, the time should be properly extended to 1h-30min for 100-200g For elements over 300 grams fire for a minimum of 2 hours for more flat elements and a minimum of 3 hours for more rounded elements.

● Fired pieces can be removed from the kiln hot or cold.
