My Sunfire Red mug has pieces flaking off. Why?

With time and continuous use, the glaze on your Sunfire Red mugs may flake off.

Our Sunfire Red glaze and two-tone glazes with it as a base have a distressed look with dark brown edges. It's natural for this glaze to gradually lose a few red pieces here and there if you use your mug almost every day; however, this typically takes years and years of repeated use. Newer mugs typically don't have this problem.
