Quality & Warranty

An excellent glass base „Made in Germany“, certified quality, continuous improvement of the technicaltechnological possibilities and our long-standing experience with heat-resistant glass guarantee high quality processed products.

We work only with raw materials of outstanding quality and with reliable partners. The Borosilicate glass 3.3. coming exclusively from Germany and the EU, guarantees that all our products comply with the applicable EU standards and regulations. Our glass contains no heavy metals or other toxic substances and with its smooth and pore-free surface is particularly suitable for people with allergies. Trendglas Jena GmbH is the first and so far the only business to be certified by the European Centre for Allergy Research Foundation.

In the certified manufacturing process several quality control measures have been put in place to ensure that our products meet the highest requirements from all aspects. The products are manufactured from machine-made bodies guaranteeing the best aesthetic and chemical, physical qualities. The very even wall thickness ensures outstanding thermodynamic qualities so that our glass products can be placed directly on heat sources.

Spouts and handles are affixed manually by our highly experienced glass blowers, adding a touch of individuality to all of our products.

The production of our articles is certified by INTERCERT according ISO 9001:2008.
