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”.

With the use of glass-ceramic both the design and performance issues were solved. A transparent piece of SCHOTT NEXTREMA® glass-ceramic retains strength at temperatures of up to 1697°F, and it’s so resistant to thermal shock that you could heat it to 1472°F and throw it in ice water 50°F without any effect, so a little rain is no problem.


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.

“We’re looking at putting windows in more models and making new models with bigger windows. It’s something that absolutely puts Fire Magic® Grills at an advantage on the showroom floor.” Mike Waller, VP of Sales, Fire Magic® Grills

“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.”Karen Elder, Product Manager, SCHOTT NEXTREMA®

“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.” Jerry Scott, Sr. VP, RH Peterson (and Grill Master)
