Glassworking, Clayworking

With the clay pits in Tuluk, and just potters in general all over the world (there are even some in Allanak), and glass for that matter too with all the available sand, I was wondering if it would ever be possible to get craft skills for these? Like.... craft clayworking, craft glassworking.

They would only be usable to proably areas with the approapriate tools. A kiln for clayworking, and a whatever for glassworking. But I think these would be neat... and fun!
