Since its foundation in 1887 by glass engineer Laurenz Lamberts, the staff at Lamberts glassworks have been manufacturing cast glasses, i.e. glasses shaped by rolling processes. The company has remained in family ownership ever since and is the only non-group medium-sized cast glass business in Europe. As the world’s first and only cast glass manufacturer at the time, Lamberts manufactured all its glasses in an oxygen-fired melting furnace, which was the most environmentally friendly method at the time. The realisation that production processes should be assessed and improved based on their environmental impact, led the use of rolling processes – a pioneering advance in the industry, which LAMBERTS implemented back in the 90s for the first time. In addition, LAMBERTS has gradually refined its manufacturing processes over the years so that the glass products are manufactured with the largest possible proportion of recycled fragments of glass at maximum quality.
