One of the world's three major Blue Onion patterns, Carlsbad is a porcelain brand originating from Karlovy Vary in the Bohemia region of the Czech Republic. In this region, where high-quality porcelain clay is available, pottery has been actively produced. Traditional cobalt blue patterns on white porcelain. In 1855, they began manufacturing Rococo-style porcelain with the Blue Onion pattern, becoming the first to produce Blue Onion in the Bohemia region. Because it is made in the kilns of the Český Porcelán company, the backstamp includes the initial "D" of the company's founder (Mr. Dubi). Below that is the German inscription "ZWIEBELMUSTER" for Blue Onion.
