Thanks to the transparent viewing window made of NEXTREMA® glass-ceramic, grill masters can see exactly what’s happening inside the grill - without having to open the lid and risk losing heat. This keeps the temperature right where it belongs, while allowing users to visually monitor the flames as they flare up. At the same time, it adds a refined design element and helps improve energy efficiency.

Fire Magic® Grills – SCHOTT’s solution for RH Peterson Co.

When engineers at RH Peterson Co. wanted to build a new Fire Magic® grill with a window, they approached SCHOTT. They asked to provide a material that could withstand intense heat and extreme temperature changes and look good while doing it.

NEXTREMA® glass-ceramic gave Fire Magic® the option of designing a BBQ window into the lid with a unique contoured surface – a novel grill design that keeps cleaning of the glass-ceramic window to a minimum.

The specially designed curved hood creates an “air-wash” effect that moves smoke and splatter to the back of the unit, so grillers can always see the action without lifting the grill hood. The contoured shape also opens up the lid surface, allowing more visibility into the grill.

FAQs

FAQ

The area of luxury grills is constantly developing, with new designs, innovations, and technology making them more personalized and versatile. The increasing popularity of cooking and eating outdoors results in larger grill units, with many an integral part of an entire outdoor kitchen.

Customization is now a large part of BBQ grill design, with customers asking for unique sizes and shapes to fit their exact requirements. Many luxury grills are also digitally connected, with cooks able to control the grill temperature with their smartphones.

Inside the barbecue itself, there’s now a wide range of grilling options and accessories available, such as rotisseries, sizzle zones, searing stations, and even a pizza oven. Combining the latest BBQ grill design with modern BBQ technology offers the outdoor chef everything they need for outdoor entertainment.

The ability to see inside the grill offers outdoor chefs more control over their cooking and greater precision with the results. Just as conventional ovens have a viewing window, outdoor grills with a BBQ window allow the cook to monitor the food without having to open the lid and losing heat.

Grills with glass windows offer grill manufacturers a wider range of design possibilities and a key point of difference, while customers benefit from a sleek, stylish barbecue that will be the center of attention in every outdoor space.

SCHOTT NEXTREMA® glass-ceramic provides a safe, durable, and reliable solution for full visibility of the BBQ grill and elaborated grill design.

 

BBQ technology has come a long way in the past 10 years, and now the outdoor chef has a wide range of grill innovations to choose from. One of the most exciting developments is digitalization, where the grill is connected online to enable the cook to control and monitor the temperature from their smartphone. This offers a precise temperature profile that can be adjusted for different types of food.

The latest barbecues also offer a range of temperature zones that give the cook a choice of cooking modes. Whether it’s slow grilling, searing, roasting, or baking, these zones provide the ideal heating option for every type of food, delivering perfect results. And with a NEXTREMA® grilling surface, design meets functionality, supporting new BBQ technology even further.

Because of the high temperatures and outdoor storage, gas grills require a unique material for the BBQ window. Glass-ceramic not only provides high heat resistance over longer periods of time, but also withstands thermal shock when the weather changes or something cold is spilt on it.

As well as being resistant to rust, glass-ceramic has high mechanical strength and durability and does not “de-toughen” over time, as thermally strengthened alternatives might do. The NEXTREMA® BBQ grill material is also easy to clean and offers long-term reliability, giving you peace of mind and enjoyment.

In our opinion, SCHOTT NEXTREMA® glass-ceramic is one of the best materials for BBQ grills thanks to its excellent transparency, impressive heat resistance, and ability to withstand high levels of thermal shock. With near-zero thermal expansion, this unique material offers a lifetime of reliability and strength for your BBQ grill, with its easy-to-clean surface delivering decades of clear visibility and delicious outdoor cooking.

The transparent glass-ceramic Burner Shield for gas is designed to protect BBQ burners from dripping fats and liquids. In addition, it provides chefs with visual feedback on ignition and size of the flame when adjusting the controls. This is a key safety feature as well as helping the chef determine the correct flame size for the food.

NEXTREMA® Burner Shields offer a number of advantages over traditional metal shields. With almost no discoloration or oxidation over time, they retain their stylish looks, and thanks to a pyrolytic effect in the hot areas, the grease can simply burn off when in use. After the Burner Shields have cooled down, the areas that have not become quite as hot can be cleaned easily using a simple soap solution, leaving them looking as good as new.

In our opinion, as one of the best materials for gas grill burners, NEXTREMA® is available in six different standard geometries in lengths from 250-450 mm, which provides BBQ manufacturers with a range of flame design options.
