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
Grilling on glass-ceramics
Our stylish grill plate, made of the high-performance glass-ceramic Nextrema from Schott, proves that a part that looks simple at first glance can be quite complex:
- Temperature resistant up to 920 °C
- Virtually no thermal expansion: can withstand temperature shocks of up to 800 degrees
- High permeability for thermal radiation
- Chemically inert – does not react with the food to be grilled and is therefore easy to clean
- Resistant to acids, alkalis, corrosion
- Mechanically very robust (impact resistant)
You can find more information and videos on this fascinating material here on our website.
Grilling on glass not only ensures good heat distribution and the best roasted aromas. Above all, no harmful smoke from half-burned fat condenses on the food to be grilled. Got curious? You can find detailed test and experience reports on the website of the BBQ.LOVE grill portal or with “our top chef from Upper Palatinate” Andreas Meier on the Facebook page of Schlossbrauerei Fuchsberg. The Grillsportverein Oberpfalz e.V. has also extensively tested the grill plate.
If you’ve got a taste for it now: You can order the glass-ceramic grill plate directly from us. Rectangular or round. In standard dimensions or in your desired format. As a single item, as a promotional gift or in series for your products. But always with the right scraper for quick primary cleaning. Just send an email to glaskeramik@irlbacher.com!

Claas S.: What is glas?”
Dr. Alexander Stoppa, Managing Engineer
“Glass is not a human invention. It is formed by nature when stones or sand melt due to extremely high temperatures and then cool so quickly that no regular crystal lattice can form. Such high temperatures occur during lightning strikes – or in volcanoes. A typical volcanic rock glass is obsidian, for example. It is very hard and breaks with sharp edges. That is why it has been used as a tool since time immemorial.
Because of the absence of a crystal lattice, glass is called an “amorphous solid”. Its inner structure is more like a liquid. Figuratively speaking, glass is a supercooled melt, or even more plastic: a liquid frozen at room temperature. This amorphous, irregular structure makes it impossible to simply chip glass – unlike aluminium, for instance.
Man-made glass has been around for at least 3,000 years. The oldest glass recipe comes from Assyria and dates back to around 640 BC. Although glass has been made, shaped and processed since time immemorial, many questions about its atomic make-up and structure remain unanswered to this day; this fascinating material defies mathematically exact simulation in many areas. As has been the case for thousands of years, glass production and processing depend on extensive empirical knowledge and “the right feeling for it”.
