My 6th grade students made ceramic mugs for their clay project. I purposely only purchased dinnerware safe glazes so that all of their projects would be functional and safe to use.
The mugs are constructed from slabs. The students traced a jar to make a circle for the bottom, and then cut a long skinny rectangle for the sides. I showed them several options on how to make a handle, but I think the favorite was to make a coil, and then flatten it.
I let the students make any design they wanted on their mugs (school appropriate, of course). Some of the students were really creative, and it was great to see what they came up with!
