Product Description
Goldie de la Rosa Bronze (New Formula) - a pinkish colour of bronze
The De La Rosa Bronze is very hard after firing. It's quite a stiff clay to work with, and yields the maximum strength - ideal for bangles, ring bands, and decorative objects.
Dried clay can be ground up to a powder and reconstituted which makes it simple and economical to use. Goldie de la Rosa Bronze shrinks by about 14%-19% during firing, depending on the shape and the size of the piece.
Goldie Bronze is an environmentally friendly product, and the binders are organic and non toxic. It contains approximately 94% copper and 6% tin.
Unlike our other metal clays, all Goldie Clays come in powder form, which is then mixed with water.
Available in size: 50g, 100g, or 200g
To mix it, follow these steps:
- Put the whole amount of powder into a jar or bowl.
- Add around 12 drops of water, or spray in a little water and mix well with a knife or spoon, adding more water as required, until you get a clay or a plasticine-like consistency.
- Roll the lump clay out thinly and fold over. Roll again, rolling away from the fold. Repeat this action several times. This is very important to ensure that all the air is removed from the clay and to get a smooth consistency before using. Insert into a plastic bag or container and wait for 30 minutes.
How to use:
- To join elements, mix a little powder with water to make a paste. Elements can also be joined with just water, in the same way as silver clay.
- Pieces can be dried naturally or by using heat, e.g. on a hotplate or in a dehydrator. Dry at 90°C or lower. Higher temperatures may cause cracking, and create steam bubbles.
- Remember to always clean your tools well between using different types of metal clay to avoid cross contamination. The above comment does not apply to metals from the Goldie Metal line, because you can mix them together with Mokume Gane, or other techniques.
How to fire:
- Ensure the clay is completely dry before firing. Any moisture will boil and ruin the piece.
- Lay the pieces in a stainless steel firing container on a layer of activated coconut shell carbon with a minimum depth 1cm under the pieces. Make sure the pieces are at least 1cm apart. Place the open container into a cold kiln and fire at full ramp to 350°C and hold for 30 minutes.
- 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 of 1cm over the pieces, and place back into the kiln.
- Full ramp to 935°C and hold for 1h20min. For pieces above 100g, hold for 1h 50min.
- Fired pieces can be removed from the kiln hot or cold.
