Janet Resnick Pottery specializes in functional tableware and garden items glazed with impressionistic landscape, animal, iris and Christmas designs. A beloved Chapell Hill pottery business that I have been collecting for years. Now I have to make room for some of my new purchases. Her pottery is meant to be used daily, is lead-free, and also dishwasher and oven safe, if started in a cold oven. Microwave is not recommended. The items I'm selling, including this mug, have been display pieces. They have never been used and are in great condition. MG 5
