This is one of Spectrum's 500 Series underglazes, which can be used at almost any temperature range. They can be applied to bisque or raw clay, and require 2 to 3 coats for opaque, vibrant colors.
Cone 06/04 to Cone 9/10.
- The sample shown is at Cone 5, but the underglze can be fired from low-temperatures (Cone 06/04) to high-temperatures (Cone 9/10).
- Some color variations will occur at higher temperature, and different clear coats and thicknesses can affect the hue of each underglaze.
The 500 Series underglazes are all lead-free, dinnerware safe, and A/P non-toxic when covered with a clear glaze.
Price is per 4-ounce bottle.
