Jaipur Blue Pottery is the most exquisite and one of the ancient crafts in Rajasthan
. This Persian craft was introduced in the mid-19th century during the reign of Raja Ram Singh. The raw materials used are multani clay or fuller's earth, quartz, raw glaze, and sodium sulfate. The artists draw the designs with a soft brush on the surface using a copper sulfate pigment for turquoise blue and a cobalt oxide pigment for deep blue. The best pieces are hand painted with conventional floral motifs and sometimes with figures of animals. Besides traditional articles like surahis, pots and cylindrical jars, other range of items include ash trays, tiles, flower pots, lamp stands, beads, ear rings, soap dishes, jugs, mugs and door knobs.
