The production range of the glassworks was very wide and diverse from the beginning. It contained historicizing, often richly decorated pieces, while in the era of Functionalism, simple elegant cups and shapes were developed, predominantly made of clear smooth glass, which were in full compliance with the principles of this minimalist style. 

These lines have been further emphasized and developed by  patenting of a new handmade technology, the so-called pulled stem in 1956, which is still one of the iconic signs of glass products from Lednicke Rovne.
