Glass enamels are applied to metal for a beautiful and colorful finish. Enamels are fired onto the metal with the heat of a torch or kiln. When using a kiln for enameling, the target temperature is in the area of 1500 degrees Fahrenheit.
Sugar looks like fine sugar.
|2. Orange Peel
Orange peel looks just like an orange peel--glossy with bumps.
|3. Full Fuse
Full fuse is when the surface is smooth and shiny.
|4. Over Fired
Over fired is when you start to see pits in the surface, black spots and sometimes the edges start creeping and/or changing color.
|Preheat the kiln between 1450-1500 degrees Fahrenheit.
Note: The first few times you use your kiln for enameling, heat the kiln to 1450 degrees. As needed, increase the temperature until the finish of the enamels is as you desire. Once you have used your kiln a few times for firing enamel, you will become familiar with the temperature that works best and can then set the kiln to that temperature from the beginning.
|Apply the enamel then place the enameled piece onto a trivet.|
|Put heatproof gloves and safety glasses on then open the kiln door. Place the firing fork under the folded mesh screen then lift the screen and trivet. Place the firing rack into the kiln on the kiln shelf and close the kiln door, doing your best to not slam the door so you don't disturb the enamels.
Note: The kiln's temp will drop as you place the piece into the kiln. Allow the kiln to come back up to the set temperature, then in about 1 minute, with your safety glasses still on, peak into the kiln to see how the enamels appear. If they need more time, close the kiln and allow it to come back up to temperature again. Wait a short period of time then open the kiln and check again.
|Once the piece is fired as you would like, place the firing fork under the trivet or use a spatula to remove the kiln shelf. Place the trivet or kiln shelf onto a heatproof surface next to the kiln. Allow all to cool to room temperature.
When enameling on metal, depending on the thickness and the technique you are working in, it is advisable to enamel both sides of the piece. This will help distribute the stress evenly and help lessen warping, which might occur as the metal and enamel expand and contract. These enamel layers are called counter enamel (the under or back side) and top coat (the layer that is facing forward).
Since this first enamel coating will be the counter enamel, heat the blank until the surface of the enamels is at least to the sugar stage. The metal and enamels will be heated again so "sugar" will eventually turn to fully fused.
|Fold the paper that caught the enamels, to form a funnel-like spout then pour the enamels back into its original container.
Repeat to add a topcoat of enamels until the finish of the enamels is as your design calls for.
