Bretts,
I think the rim is too heavy also, the angle of the photo accentuates that as well. It will take a substantial plant to bring it down to size.
Petra,
Glad you like the pot!
Rarest succulent I grow, tough to say as I have many that are very hard to obtain. Aloe pillansii is up on the endangered list with less than 200 in habitat, I have 4 plants. Cyphostemma uter, their numbers are dwindling as well, I have 3 of them. I could go on and on but you get the idea.
Here's another rare one I just got, Digitostigma caput-medusae

This pot was made from scrap black mountain clay that I mixed with tissue paper resulting in what is called "paperclay". The fibers in the clay make stronger bodies and bonding as well as reducing weight. I wanted to make the walls an 1/8" thick and could not have done that with traditional clay, it would have been too brittle. The texture on the outer surface is from slip made from the scraps and brush on diagonally. The grog shows up do to the brushing, it wipes away the fine clay that makes the surface smooth.
