You can't tell from the pictures, but these coil pots are huge! The students are required to build them at a minimum of 10 inches in height. They also must be waterproof by sealing the inside and then eventually glazing them. Another requirement is to personalize them in some way. I showed them different ways that they could personalize their pots such as adding spirals, braids, spheres, vertical coils, animal faces/bodies, abstract shapes, lettering, and how to make the pot wider or more narrow. They are all very different, which was one of the goals. The kids are really enjoying the challenge of building big. When they are completely done with them, we are planning on having a party and the pots will house the food.
