Carlsbad or Karlsbad is a mark used on china made by several factories in Germany, Austria, and Bavaria. Many pieces were exported to the United States. Many of the pieces are biscuit jars, bowls, plates, and platters from the late 1800s and early 1900s. Carlsbad is a city in Czechoslovakia, home to the factories that made the exported porcelain. Most of the pieces available today were made after 1891.
