Here is a photo of Safi, where I went with Judy a couple of weeks ago. They ship phosphate from here, and also the seaport town is known for its sardines, and pottery. So we had fish for lunch, then went tromping around (literally) the clay where they make pots.
Big old clay kilns, and guys tromp around in their bare feet mixing the clay. (that's Judy watching)There was one pot that had some grey stuff in it and lo and behold, I recognized it as...bentonite!
Shades of Wyo-Ben in northern Wyoming. .
It was a very enjoyable day.
Some places use the chards of broken pots to make
very attractive walls around their business
