Silver outdoor grill with glass-ceramic viewing panel

Master the Grill – through a glass-ceramic window

Fire Magic® Grills are hot – in more ways than one. According to RH Peterson Co., parent company of Fire Magic®, they put out more BTUs (British Thermal Units, the “horsepower for grills” so to speak) per square inch than any other residential-available grill. And for homeowners installing outdoor kitchens, they represent the pinnacle of design. So when engineers at RH Peterson Co., wanted to build a grill with a window, they needed a material that could withstand intense heat, extreme temperature changes, and look good while doing it.

Glass-ceramics to master the task

In the past, a glass window on the barbecue grill was once a standard feature. But the tempered glass grill makers used wasn’t up to the task as it tended to weaken or break when exposed to high heat or sudden temperature changes (e.g. rain). To compensate, the windows were usually tiny. And over time, smoke and grease combined to stain the glass an uncleanable grayish-yellow. Windows soon disappeared from grills altogether.
However, grill masters still desired a way to see inside the grill while the food was cooking. Being able to catch flare-ups means the difference between “grill master or grill disaster”.

A transparent piece of SCHOTT NEXTREMA® glass-ceramic retains its strength even at the high temperatures generated during grilling and is highly resistant to thermal shock. If the glass-ceramic were heated to 820°C (1,508°F) and then immersed in water at room temperature, there would be no effect at all. Its thermal expansion is close to zero.

Grilling with all senses

Incorporating NEXTREMA® glass-ceramic allowed Fire Magic® to design a viewing window into the grill lid, with a unique contoured face. A novel design approach that reduces frequent cleaning of the glass-ceramic window to a minimum. Their specially designed curved hood creates an “air-wash,” moving smoke and splatter to the back of the unit, so grillers can always see the action without opening the hood at all. The contoured shape also opened up the lid surface, allowing more visibility into the grill. A true grill masters dream.

"These large windows are more than just a pretty face. They have a design purpose and a functional purpose. Grill manufacturers can separate themselves from the competition with a unique lid design and grill enthusiasts can monitor their food even when the lid is close."

"I was one of the first to install the Echelon grill in my own home and I fell in love with it. As far as cleaning, due to weather, the outside gets dirtier than the inside."
