VARIETY. GLASS.
Think-tank

Industrial hot processes have one thing in common: they need viewing panels for optical control and monitoring. As large as possible. So that you can see all the details. As small as possible, so that heat loss is kept within limits. How to solve this dilemma? With an infrared (IR) reflective coating on transparent NEXTREMA glass-ceramic from SCHOTT:
The coating applied to one side of the glass-ceramic reflects the heat radiation back into the process and thus can significantly reduce heat loss, compared to an uncoated NEXTREMA pane. The degree of IR reflection depends on the wavelength of the heat radiation. The coated glass-ceramic is available in different shapes and formats and sets hardly any limits to the free view of the processes.
Which hot processes do we have in mind?
We have a few more ideas, for example
- Soldering ovens in electronics production
- Drying ovens
- Tempering furnaces
- Annealing and hardening furnaces
- …and countless other applications that you can probably think of right now.
Let’s talk about it!

Applications in detail
CARY – the smart modular construction kit for your individual health management system
Protecting our employees from health hazards in the workplace is our top priority. As a family-run company, we rely in these times on a smart protection concept that works reliably, fulfils the legally required verification and documentation obligations and is so easy to use that employees are happy to accept it.
Because such a system, suitable for medium-sized manufacturing companies, was not available on the market, we developed CARY ourselves in a very short time. Our own comprehensive solution construction kit for HMIs gave us outstanding support as we did not have to develop numerous subsystems from the scratch, such as environmental sensors, anti-microbial coating of glass or RGBW-LED lighting.
The advantages of our CARY at a glance:
- CARY reduces risks
- CARY provides safety
- CARY reduces costs
- CARY simplifies communication
- CARY makes processes lean and efficient
- CARY easily communicates with the building automation
- CARY is open für future extensions – and an irreplaceable assistant not only in pandemic times








The simple, elegant design takes the latest findings in usability research into account and sets milestones in the digitalisation of documentation and testing requirements. We have placed special emphasis on data security – and still managed to ensure open interfaces in order to enable system integration of CARY practically everywhere. See for yourself!

Ask the Irlbachers
Hartmut P.: “Frequently, I come across the term ‘glass frit’. What is that?”
Alexander Stoppa, Technical Manager
The base material for glass frit is finely ground glass, for example from cullet of our production. If you “cook” this glass powder at about 750 °C, it melts on the surface; the powder particles “bake” together. At this temperature, glass does not yet become molten; therefore, wine or window glass cannot be formed from the “baked” glass frit. Materials engineers generally refer to such “baking processes” as “sintering”.
If the backed glass frit is quenched, the result is a porous material that is well suited as a filter in laboratory technology or the process industry. If this material is ground, we also refer to the resulting powder as glass frit.

For Irlbacher, glass frit is important in two ways: as an essential ingredient in both the ceramic inks and the metal pastes we use to print electrical circuits on the glass. After all printing processes, we “bake” our blanks in the toughening furnaces. During this process, the glass frit fuses inseparably with the tempered safety glass. The inks, circuits and glass form a monolithic, substance-to-substance bonded composite.
