The Schott ROBAX® brand, which specialises in glass that withstands extreme variations in temperature, has developed a new range of glass for fireplaces and wood-burning stoves: NightFlame®, a real innovation in the design of stoves, inserts and fireplaces.
This new black-tinted semi-transparent glass has features that are highly appreciated and sought-after in the field of glass-ceramics:
- A warm fire
- Greatly reduced visibility of the combustion chamber once the fire is out
What is glass ceramic for wood-burning stoves and inserts?
This type of glass has the best heat resistance characteristics. It has a relatively low coefficient of expansion, enabling it to withstand the most extreme temperatures (cold and hot).
Glass ceramic guarantees optimum safety when using your wood-burning stoves and fireplaces.

ROBAX NightFlame® glass for a cosy atmosphere
NightFlame® glass ceramic is a semi-transparent glass that reduces the visibility of the combustion chamber when the fire is out, thus preserving the elegant design of your heating appliance without allowing residues and dirt to show through.
Specially designed for wood-burning appliances, NightFlame® has the ability to let certain light waves pass through, allowing you to enjoy the flames of your fire just as well as you would with clear glass. Once combustion is complete, the glass becomes opaque (Dead-Front effect), giving way to a black pane.
With its sober, elegant design, NightFlame® vitroceramic glass becomes a decorative element in its own right all year round.
It is now available in flat and curved glass.

This new ceramic glass is a real breakthrough in the field of glassware. It brings all the advantages of ceramic glass while offering a refined design. NightFlame® glass was presented as a real innovation at Progetto Fuoco in 2022 and was presented there again in its curved version in 2025.



Cleaning:
Cleaning NightFlame® glass is identical to cleaning standard glass-ceramic. The added bonus is that you don't have to clean the glass as soon as combustion is complete, because the dead-front effect automatically removes the soot residue from view.
Despite the reduced visibility of ashes and soot deposits, we recommend that you clean the glass of your appliance regularly. There's nothing like the Schott sponge for optimal dry cleaning.
These glasses will soon be available for sale in flat and curved versions.
