285A - Axner Underglaze Pens

Available from Seattle Pottery Supply when we last checked. Sold from the shop’s own store; the price there is the one that counts.

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.
