Csonkaglas Ltd., functioning today as a group of companies, named Csonkagroup, was founded by Csonka Tivadar in 1982. The company was partner of SCHOTT Jenaer Glas GmbH since 1996 concerning the production of heat resistant glassware. As the production of household glassware was stopped by the German company in 2005, Csonka és Fiai Ltd. took over the production of these products under an other new brand, named Trendglas, becoming this way one of the biggest manufacturer of heat resistant glass in Europe. By founding Trendglas Jena GmbH in 2006, the company became an international establishment. Today Csonkagroup is manufacturing/distributing household and laboratory glassware, glass tubes and crystal glasses, and his determining aim in the future is to develop the solar system protected by own patent.
