The vessels are various sizes. They   are  4 1/2" up to 8" tall. They range  in width from 5" to 9".   Each one is hollowed on the inside and most are painted on the inside as well. The pattern on the surface of the vessel is not repeated on the inside. The wall thickness will vary somewhat, but is usually between 3/8" and up to 1" thick depending on the shape of the vessel.
