Meissen porcelain is a type of porcelain that was eveloped from 1708 by Ehrenfried Walther von Tschirnhaus. It was the first successfully produced hard-paste porcelain in Europe. After his untimely death that October, Johann Friedrich Böttger, continued his work and brought porcelain to the market, and he has often been credited with the invention. The production of porcelain at Meissen, near Dresden, started in 1710 and attracted artists and artisans to establish one of the most famous porcelain manufacturers, still in business today as Staatliche Porzellan-Manufaktur Meissen GmbH. Its signature logo, the crossed swords, was introduced in 1720 to protect its production; the mark of the crossed swords is one of the oldest trademarks in existence. It dominated the style of European porcelain until 1756.
