Deneen Pottery has been hand making stoneware mugs in St. Paul Minnesota since 1972. These 10oz. mugs are lead free and food safe. Each mug is hand thrown and kiln fired, is very durable and safe for microwave, dishwasher and freezer. This mug is red with sand white marbling. The medallion features the Museum's historic Red Barn with the first Boeing aircraft the Model C Floatplane, flying above it.
