I hope to never have it truly tested LOL. But the compound formula and thickness is what determines the temperature rating. And I do not have a picture of the bottom side of the lid, but it too has the same thickness as the sides and bottom of the box. In addition, there is a beveled edge to help shield the inside from extreme heat for an [undetermined] length of time. Most brand name fireboxes are not nearly rated for as high of heat exposure as this one. There is obviously a limit for a particular temperature and/or time exposed to some temperature that would cause it to fail. I have never put it through that kind of heat, mostly because a common house fire can be around 1100 degrees Fahrenheit. Quite a challenge to create temperatures near there.

Looks a good option, thanks 👍

If you know anyone that is good at working with refractory cement, a homemade firebox can be made to whatever size you desire. Courtesy of my brother…

At present, it is painted with high heat, flat black header paint. Rated for 2000 degrees Fahrenheit. Made with the same refractory cement as the steel blast furnaces in Canada. Weighs in at about 55lbs+ empty.

What an achievement, well done! 
 

Congratulations!
