The Glas- und Kunststofftechnik Freital is the successor from the traditions from Sander brothers & Co., wich was founded in1906.

Sander brothers & co. was one of the german pioneers in development hardened glasses.

Several of the first hardenedglasses came under the trade mark "FIRMUS" from Freital.

Also in future we produce flat glasses in highest quality, if you need high heat resistant and pressure resistant glasses.
