Goldie Yellow Iron - a lovely yellowy-silver colour.

**Requires Kiln Firing

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 and repair seams in Goldie Lemon Brass clay 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 90ºC or lower. Higher temperatures may cause cracking, and the creation of steam bubbles.
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.

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. Do not cover with carbon for this step. Make sure the pieces are at least 1cm apart. Place the open container into a cold kiln and fire at full ramp to 580°C, and hold for 30 minutes for pieces up to 100g. The clay will change colour 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 of 1cm 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 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.
Goldie Yellow Iron shrinks by about 5%-14% on firing, depending on the shape and the size of the piece.

* These clays take texture very well but we suggest using quite a deep texture as these show up better than shallow textures.
* Shake the bag well before opening to ensure an even mix of metal powder and binder.
* Always wear a respirator mask to prevent breathing or ingesting Goldie Clay powder*
