Drysalter
（重定向自Dry salter）
Drysalters were dealers in a range of chemical products, including glue, varnish, dye and colourings. They might supply salt or chemicals for preserving food and sometimes also sold pickles, dried meat or related items. The name drysalter or dry-salter was in use in the United Kingdom by the early 18th century when some drysalters concentrated on ingredients for producing dyes, and it was still current in the first part of the 20th century.
