Thai kilns have a long, primarily Chinese-influenced tradition of pottery making. Of the various styles, hand-painted 14th century Sangkhalok, produced in Sukhothai, and 19th century Bencharong with decorative porcelain bowls, jars and spittoons are the most popular. Bencharong has proved the most desirable among Thai and foreign collectors due to the rarity and rich surface decorations. The northeastern community of Dan Kwian produces as distinctive range of rust-red objects including vases, flower pots and tiny ornamental accessories. In northern Thailand, high fired seagreen celadon produces an effect similar to venerable Sangkhalok ceramics.
