vase help

please help me with a vase I acquired :


this is the hardest part, describing the exterior part of the vase, the vase
actually looks as though it has been dipped in sand or some other crushed
material then the artist has painted a guilded pattern in over the sand
like material.

so my best description all up is a vase made of a cream pottery with
underglazed blue enamel dipped in sand like material with a hand painted
guilded pattern. hope anyone can help with the name of this technique of the
description above . that's the best I can do!
