There are exactly three of these out in the world, and I have reason to believe that this is the last one. I'm out of this glaze, and it appears that the oxide which provides that mirco-crystal amber glass isn't part of my dry materials stash. It's a mystery, in fact. 
 
This beaut is just under 10" tall and has it all. Carbon halo on the handle and spout, wonderful form, and good volume. Probably looking at 5-7 cups of tea here.
