Oil-based clay doesn't harden, it stays nice and soft so can be used over and over for other projects. You would need to create a mold if modeling in this material and cast a copy in a hardening resin for assembly and painting.
If you don't want to get into molding & casting, you will need a good quality clay that does harden such as Super-Sculpy. This needs to be fired in an oven to cure.

That's more likely to be a pottery type of clay you used then. Super-Sculpy is pretty expensive and comes in small packs. I guess your class would go for the cheaper firing material commonly used for making plates, jugs, vases etc...
