This clay comes in dry powder form. The dry powder can be kept for years. Mix only the amount you need so you always have fresh clay with the perfect texture. You'll have longer working time and a more workable product when the clay is mixed fresh as you need it.

TO MIX

Put the all amount of powder into a jar or bowl.

Add about numerous 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 of a plasticine like consistency. The water does not need to be distilled – tap water is fine.

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.

TO USE

To join elements and repair seams in Goldie Lemon Brass™ clay mix a little powder with water to make a paste. Elements can also be joined with the water only method 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 200ºF (94ºC) or lower. Higher temperatures may cause cracking, and the creation of steam bubbles.  Larger pieces can be dried in a kitchen oven as long as 200ºF is not exceeded.

Remember to always clean your tools well between different brands and types of metal clays to avoid cross contamination. This does NOT apply to metals from the Goldie Metal™ line because you can mix them together for Mokume Gane and other techniques.

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 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 580°C(1076°F) and hold for 30 minutes for pieces up to 100g. Clay changes color to dark brown.

• 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 5 cm (2in) over the pieces, in order to reduce evaporation of tin, cover the container with a lid,  and place back into the kiln. Do a full ramp to 870°C (1598°F) and hold for 2 hours.
• Fired pieces can be removed from the kiln hot or cold.
• After removing the cover, appears white-yellow precipitate from zinc oxide. This is normal and does not cause changes in the properties of coal.
