Wheel thrown, hand painted and carved porcelain mug. Microwave, oven and dishwasher safe. Holds 13oz. and measures approximately 5 inches high by 3 3/4 inch wide at the rim. Features graphic butterflies and cobalt blue markings. Icy blue interior glaze and satin clear exterior glaze. All of my surface work is created with underglaze (liquid pigmented clay) using a variety of brushes, slip trail bottles, and carving tools. Please note that each mug is one-of-a-kind with slight variations from the images shown in this listing.
