Hardened glass

Glass! Natural, transparent and versatile! But glass has its limits. Glass has to be manufactured with an energy-intensive process, is heavy and breaks violently. However, glass can be chemically hardened. But these methods are expensive and requiring a great deal of time and energy.

We have developed a new technology that makes it possible to overcome all of these disadvantages. 

Compared to current processes, 2MH state of the art methods, save up to 95% of the energy, increase production capacity by up to 16 times and require only 5-30 minutes for the hardening process.

The disruption for the glass world!

Our manufacturing process is available for flat glass and container glass.

Other possible applications:
display glass, vehicle glazing, building glazing, food packaging and much more.

With this new technology, the physical limits of glass will be altered forever.

The most important evaluation criterion: from now on it is economically possible to use strengthened glass in a wide range of applications!  Glass can now become thinner and yet stronger. We no longer need specialized glass for unique applications.  We use the glass that is most widely used worldwide: Sodalime! Sustainable process optimization in the production of “super-strong” glasses with revitalization of molten salts used in the chemical strengthening of glass.
