285A - Axner Underglaze Pens

Developed for cone 05 and 06 firings, most of the colors do quite well at much higher temperatures. 

• Cone 06 - 04: All colors remain strong and vibrant
• Cone 6: Most colors remain strong and vibrant. Exceptions: Chartreuse, Light Yellow, and Light Pink are weak. Greens, Peach Sun, and Purple Maroon change color somewhat.
• Cone 10: Same as cone 6 with the following exceptions: Chartreuse completely disappears.

Note: Only food safe if a food-safe clear glaze is applied over these underglazes.
