A tradition of innovation

The heart of RITZENHOFF AG still beats where the company’s history began more than 100 years ago – at its headquarters in Marsberg in Germany’s Sauerland region. As far back as the 18th century, wood from the dense local forests was used in the first glassworks to fire the melting furnaces that turned quartz sand into glass.

The family-run company RITZENHOFF has remained true to this tradition, evolving over the years from a glass-making workshop to one of Germany’s best-known high-tech glass factories. Read on to find out more!

1992 Launch of the RITZENHOFF brand

In 1992, the manufacturing based for the graphic design division is relocated to Essentho.

The launch of the RITZENHOFF brand develops from the ingenious idea to produce decorated designer milk glasses. The simple but brilliant principle is to use the opaque whiteness of the milk in the glass as a canvas on which individual artists and designers can express their ideas. They don’t design new glasses, but simply create new decor for the respective standard glass form. The milk glass line is soon followed by colourfully decorated beer, champagne, wine and schnapps glasses and other designer gifts for the specialist retailers.

In addition to class mouth-blown glass production, this branch of the company quickly builds on its position and becomes the most important part of the business as it is known today.

1957 Glaswerk H. und Kl. Ritzenhoff KG

Over the years, Heinrich Ritzenhoff receives increasing support from his son Klaus to help him manage the company. The company has developed so well economically that an addition company is founded in 1957 under the name “Glaswerk H. und Kl.
