What Cone Do I fire decals?

A lower firing temperature is sufficient for decals on this ware due to its soft glaze. Most shades of red should not be fired hotter than cone 018 regardless of ware. Overfired red will usually turn grey. Pinks are fired to a higher temperature to bring out their true shades.
What temperature do you fire decals?
Preheat slowly to 1,000 °F [578 °C] to allow the decal medium to burn off excess & avoid pinholes or blisters. It is also important to allow ventilation in the kiln (no peephole plug and crack the lid open slightly) up to the 1,000 °F [578 °C].What Cone do we glaze fire at?
For example, most commercial glazes recommend bisque firing to Cone 04, and glaze firing to Cone 06 (which is cooler). The reason for this is to make sure all the carbon and other materials in the clay burn out during the bisque firing.How do you apply fire and ceramic decals?
Immerse decal in lukewarm water for 20-30 seconds. Slide decal from the backing paper and position on glazed ware. (If decal doesn't slide off easily place it face up on a paper towel for a minute.) Be sure decal is applied to your project face-up; otherwise it will burn completely off.Which is hotter cone 04 or cone 06?
That is not to be ignored!Cone 6 is about 400 degrees hotter than cone 06! As you can see from the pyrometric chart (above), the “0” serves as a negative sign. Therefore cone 05 is cooler than cone 04 whereas cone 5 is hotter than cone 4. For the most reliable results, it is best to match your clay with your glazes.
