Math problems solved incorrectly adorn this large mug. It makes me giggle. Perfect for folks with a quirky sense of humor, teachers, graduations, or mathematicians. This mug would make a great graduation gift!

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 one will hold about 18 oz.

Please keep in mind that pottery is handmade and will have natural variations that make it unique.

The inside of this mug is glazed a beautiful sea green blue color. It accents the spiral in the bottom of the mug rather nicely.
