The Texas Fireframe® grate was invented by PhD physicist Dr. Lawrence Cranberg for a hotter fire that’s easier to maintain, using split or unsplit logs.
Discover how easy it is to start and maintain a fire that produces much more heat compared to conventional fireplace grates.
Two adjustable arms open up the hottest part of the fire to the room. In our Instructions we show you how to build a fire and arrange logs of different sizes to produce the most heat. Logs burn full length, slowly and evenly, with no need for poking or prodding to revive the flame.
With a range of sizes, decorative accessories, and customizable options, our beautiful fireplace grates add warmth and style to your home. Enjoy even-burning fires that deliver much more heat and are easy to maintain..
Invented by a nuclear physicist, the Texas Fireframe grate is the first and only method of fire-making based on modern thermodynamic theory. Our grates are made in the U.S.A. of heavy-duty, hot-rolled steel, and have been known to stand up to 25 years of fires. It’s also the only fireplace grate that is described in referenced scientific literature.
Hotter than fireplace heaters and much less expensive than fireplace inserts, our grates let you keep the beauty and charm of an open fire, while increasing the efficiency of your indoor or outdoor fireplace. Every grate we manufacture is the culmination of scientific research and traditional American craftsmanship. … It’s a heat revolution for your fireplace.
No wonder the press was impressed. The Texas Fireframe grate was featured in news stories on CBS and BBC. TIME magazine dubbed it “The Physicist’s Fire.” Better Homes and Gardens said it “opens up the hottest part of the fire and beams heat straight out into the nearby living spaces.”
Here’s how Scientific American described the ease and efficiency of this fire grate: “The burning was slower with this arrangement…and required no rotation or stirring of the logs.”

It all began in December 1974 when the Cranberg family was feeling the cold chill of the Arab oil embargo. Homes all over the country had their thermostats turned down, and Dr. Cranberg decided it was time to get some heat out of his fireplace.
He built a fire that quickly fizzled out, and then he attempted another with similar dismal results. A physicist with credentials ranging from Harvard to the Manhattan Project to UVA professor, Dr. Cranberg decided more kindling wasn’t the answer. The answer was Kirchhoff. “I was about to give up,” he said, “but decided to use a poker to roll back the top log to peek into the hidden heart of what fire I had started. Sure enough there were hot coals hidden in the space I had opened up. It flashed into my mind that I was looking into what Gustave Kirchoff taught us a century and a half ago was a Hohlraum (German ‘hole space’) cavity that has very favorable radiating properties, and then something remarkable happened. As I held up the near side of the upper log, a line of flames erupted from left to right on the log below where radiation was striking it from the upper log… an unforgettable moment.”
Hotter than fireplace heaters and much less expensive than fireplace inserts, the Texas Fireframe grate is the perfect housewarming present, holiday gift, or addition to your own fireplace if you love a hot, easy-to-light, simple-to-maintain log burning fire. It delivers 5 kw of radiant power with significantly improved efficiency of biomass compared to the conventional fireplace grate. (That means you’re getting more heat from each log burned.) Once you experience the ease and warmth of the “Physicist’s Fire,” you’ll understand our customers’ grate reviews.
A physics professor who restored an ancient hearth and chimney stone by stone told us he chose the Texas Fireframe grate “to keep the beauty and charm of an open fire while enhancing efficiency.” We couldn’t have stated it better. Scientists and engineers often mention their professions when they place an order, and we’re pleased to have their endorsement.
Not surprisingly, our fireplace grates are also popular among architects because they merge energy efficiency with the aesthetic appeal of a real wood-burning fire, without tubes, inserts and unsightly contraptions. As Einstein is credited as saying, “Everything should be made as simple as possible, but not simpler.” The Texas Fireframe grate has been called “deceptively simple.”
This winter, bring the warmth, ease and beauty of the “Physicist’s Fire” into your home. When you do, we look forward to hearing about your experience. Let us hear from you!
The Texas Fireframe grate not only generates more heat, but it makes it so easy to start and maintain a fire, that you’ll build more fires, which generates even more heat!
