The glazes on this pot are called Smokey Blue and Silky. There's so much happening on the surface of the pot! This pot will fit your 6" plant pretty well, but it may be better to plant directly into the pot. I leave the inside of my pots unglazed because I've heard that the roots like the texture of a unglazed clay. There is a drainage hole and saucer.
If you would like your items shipped, let me know and I'll look up the cost of shipping and add that to the listing.
I am a potter in San Jose. Please let me know if you have any questions!
