Original Karolinka plant was built in the 19th century, when the greatest development of glass production took place.

In 2008, Crystalex had four production plants: Nový Bor, Karolinka, Hostomice nad Bílinou and Vrbno pod Pradědem and had a turnover of about CZK 1.5 billion.

In August 2009, the CBC Invest glass group, backed by Russian and Slovak capital, represented by the Czech businessman Jiří Hudera, bought production plants in Nový Bor and Karolinka for CZK 362.7 million and transformed it into a private limited company.

Since then, the new owners have invested another roughly 200 million crowns not only in the renewal of production and technology, but also in the modernization of the complex.

Since 2011, it is exhibited at the newly created Center of Glass Art in the town of Sázava in the Benešov District.
