It'd be nice to see more of this stuff out there. All I ever see are cheap terracotta knock-offs made in China.
I don't know much about pottery, but I do know that much of the REAL, ORIGINAL indigenous pottery back in the day was all low-fired because it could be used as a cooking pot on a fire that way. I suppose you'd lose some bit of the authenticity firing the stuff to the level we'd be looking for to withstand years outside on a bench.
