I only really popped into Bennett's in order to buy a bit of extra clay for my sculpture class, however, I really liked the place.
They have terracotta pots of all shapes and sizes, as well as stoneware and building products, such as glazed bricks and tiles.
It is a bit of a maze when you first enter as the stock room isn't really manned. This is because Bennett's are primarily manufacturers (which means everything is really cheap) and when I was there I had to go and hoy a dude driving a fork lift full of terracotta potts to get served. But that's kinda cool in itself.
Oh and did I mention they also sell, clay by the bag, which is pretty cool, and hard to find, and also the reason why I went there in the first place. read more
