Direct Answer:
Schott ROBAX high-temperature glass is the optimal material for cast iron stoves because it resists thermal shock, maintains clarity during operation, and supports high-temperature combustion essential for modern efficient stoves.

1. Thermal Shock Resistance
Cast iron stoves reach very high temperatures during operation. Standard glass often cracks or shatters under these conditions. Schott ROBAX is a ceramic glass capable of withstanding rapid temperature changes without damage.

2. High Transparency Under Heat
The clarity of the viewing window allows users to monitor the flame and adjust fuel or air supply, ensuring optimal combustion. Its resistance to soot accumulation reduces cleaning frequency.
3. Support for Secondary Combustion
Modern stoves with secondary combustion require high temperatures in the upper chamber. Schott ROBAX tolerates these temperatures without deformation, allowing the secondary combustion system to function efficiently.
4. Safety Advantages
- Shatter-resistant under normal stove operation
- Reduces risk of injury or property damage
- Works reliably over the stove’s lifespan
5. Summary
Schott ROBAX high-temperature glass is a key component in reliable, efficient, and safe cast iron stoves. Its unique properties ensure thermal durability, clear visibility, and enhanced secondary combustion performance.
