1. Using a mesh grid on a gas stove: Firing Art Clay Silver on a gas stove PDF
2. Using a torch
3. In a special hobby kiln, ceramic kiln or enamel kiln (temperature controlled)

Always fire your silver clay long enough. It is better to fire slightly too long than too short. The larger or thicker your piece is, the longer it needs to be fired. Check the firing chart to see which firing method can be used for regular silver clay and the minimum firing time required. Longer firing will not damage the silver and is even recommended.

1. Firing regular silver clay on a gas stove
   On a gas stove you can easily fire smaller pieces up to approximately 10 to 15 grams. Place the piece on a mesh grid where the flame touches the grid. Make sure the clay is fired long enough. Only start timing once the silver develops an orange glow. This is the temperature at which the silver starts to sinter. On a mesh grid the temperature is approximately 700°C.
   Please note: this method is not suitable for Art Clay Silver 950 Professional.


2. Firing regular silver clay with a torch
   Firing with a torch requires some practice. When using a torch there is a risk that the piece becomes too hot and melts. Move the flame gently up and down to maintain control over the process. Once the piece starts glowing, it is important to maintain this temperature long enough. Always use a heat-resistant surface such as a fiber board, ceramic tile, mesh grid or charcoal block.

3. Firing regular silver clay in a hobby kiln
   When firing in a kiln it is important that the kiln temperature can be accurately controlled, so the piece does not become too hot and melt. A temperature of 800-820°C is commonly used. A kiln provides, when used correctly, the greatest certainty that the entire piece has been heated evenly and thoroughly. This greatly reduces the chance of breakage. Another advantage is that you can also work with other materials in the kiln, such as glass, gold foil, gold paste and enamel.


4. Firing Art Clay Silver 950 Professional in a hobby kiln
   Art Clay Silver 950 Professional can only be fired in a kiln. Place the piece in a cold kiln. In the first phase heat to 500°C and hold this temperature for 10 minutes to burn out the binder. Then continue to the second phase and heat at a normal rate to 870°C. Hold this temperature for at least 1 hour. Afterwards allow the piece to cool in the kiln to at least 200°C or until completely cool.
