This large mug features a crystal cradled in a nest of fern foliage. The crystal is from the mountains of Arkansas, one of the finest sources of crystal quartz. The mug is hand-thrown on the wheel, using stoneware clay. It is glazed in midnight snowflake with snow white and waterfall green details. Holds 10 fluid oz. Food-safe and fired to 2322°f in the belly of my Dragon Kiln. Enjoy spending your mornings, studying the facets of the crystal while sipping your favorite beverage.
