This is a large mug! It features 2 incorrectly solved math problems. This might be a good one for an elementary school teacher. I've seen what kids do with fractions. Oy!

The mug was made on a kick wheel and fired to cone 5 for durability. It's food, dishwasher, and microwave safe. All glazes used are lead-free. This mug will hold over 16 oz. I've glazed it a cheerful shade of apple green inside.

Please keep in mind that pottery is handmade and will have natural variations that make it unique. This mug has a raised gray speck just over the number 5 (see detail photo).
