Tradition & Modernity

Founded by Anton Müller as a small sheet glass works, we have long since become one of the leading international glass specialists. But we don’t regard ourselves purely as an industrial enterprise, but more as an artisanal craft of sophisticated glass culture. State-of-the-art technology is an integral part of their company, but their greatest assets are their employees, whose extensive experience is often handed down through generations.

Every move gives their products their individual touch, then and now. Tradition and innovation melt to supreme glass art in each and every one of their crystal glasses. It is with this high standard of excellence that we look forward to the next 150 years, with high expectations and conscious of their history.

We are convinced that companies must act and manage their resources responsibly to prevail in the future. That’s why we aim to manufacture their products with minimal resources and optimized energy input to avoid unnecessary environmental burdens. We use as many regional resources and materials as possible to manufacture their products. We continuously strive to achieve an integrated and sustainable life-cycle assessment for all of their processes and products.


We have implemented an environmental management system certified according to ISO 14000:01 to ensure a sustainable corporate concept with consistent product quality. In addition, TÜV Rheinland audits their environmental protection and sustainable production measures every year.

their detailed analysis of all raw materials associated with production aims to avoid contaminants from the onset and to use recyclable materials wherever possible. We rely on regional raw materials (particularly quartz sand, a key ingredient) and recycled glass from their own production to guarantee short transport paths. We also give preference to regional energy sources for their production plants.

We are committed to continued process innovation to minimise their energy use in glass melting. A closed cooling water circuit, heat recovery technology, filter systems as well as UV and laser technologies reduce their energy consumption and make sure that water is returned to the environment in clean condition.

We are particularly proud of their oxyfuel technology, which significantly reduces their carbon dioxide and nitrogen oxide emissions. This technology enables us to use 30% less energy in production compared to conventional gas-heated glass melting furnaces.


Tritan® crystal glasses not only are brilliant, break resistant and dishwasher safe, but also stand out for their sustainability. their consistent selection of low-emission, recyclable raw materials for production makes their products especially durable and environmentally friendly. Approx. 50% of each individual glass consists of recycled Tritan® crystal glass. Based on their detailed analysis of all raw materials, we can produce high-quality glasses that are 100% food-safe and 100% BPA-free.


Their packaging is mostly FSC® (Forest Stewardship Council) certified and marked with the green dot to show it is made from environmentally friendly, recyclable materials. their filling pellets are biodegradable as well. Boxes can be reused, e.g. for storage or moving. Thanks to the unique design, the product boxes also make ideal gift packaging to give your loved ones a special treat.
