This is the original Ripple Pottery Mug. Brian has been creating this form for 20 years. This high-fire stoneware mug will hold up to 16 oz of your favorite hot beverage. It features a wider belly and tapered shape that retains heat even longer, and gives a more ergonomic feel to the mouth of the mug. Each mug is signed by artist Brian O'Hare. The dimensions of this mug are approximately 4.5" tall and 4" diameter at its widest point. This mug is oven, microwave, dishwasher, and food safe.
