I’ve replaced enough stove glass to know when something is worth recommending, and this Harman Mark II Ceramic Glass Panel absolutely is. Designed as an OEM replacement ceramic glass, this panel measures 8 1/2" x 4 1/2" and is made from high-temperature pyro-ceramic glass that can handle up to 1,400°F without cracking under pressure. If your current glass is cloudy, cracked, or holding your fire hostage behind a smoky blur, this restores the clear, uninterrupted flame view your Harman stove was built for.
This is not tempered glass pretending to survive a wood stove—it’s the real deal. Pyro-ceramic glass has minimal thermal expansion, making it the safe, correct choice for high-heat environments. Proudly made in the USA, this panel fits Harman Triple Frame, Magnafire Elite, Mark II, Mark III, SF-150, and SF-250 wood stoves with precision. Clean fit, reliable performance, and a fire view that finally looks alive again—exactly how a Harman should burn.
Measurements: 8 1/2" x 4 1/2"
Glass Type: Ceramic 3/16" (5mm) Thickness (Pyroceram / Robax)
Operating Temperature: Up to 760°C / 1,400°F
Color: Clear (ceramic glass has a natural amber tint)
Part #: 3-40-450850
If your original panel is hard to find or no longer in production, I can custom-cut high-temperature ceramic glass made precisely to your measurements.
