Jaslo Glassworks was founded in 1922 and for the next thirty years produced glass tableware such as bowls, vases and drinking glasses. In addition, the company also made various glass bottles and jars for packaging in the food and drink industry.
In 1954 production started on railway signalling lenses for PKP, the Polish state railway company. The Glassworks also started making protective glass lenses used in the production of safety helmets for welders.
At the beginning of the 1960s, the product range widened to include coloured signalling lenses for railway and road networks, as well as for seaports and airports. A major new product for the company was the introduction of headlamp lenses for the automotive industry.

Alongside the production of this technical glass, Jaslo Glassworks has also been making antique stained glass, using traditional methods dating back to the nineteenth century. Antique stained glass is available in a variety of shades and colours, and has been used on many prestigious projects, including the restoration of the Royal Castle in Warsaw.
