Fire Brick
The trick with wood is that while it starts to burn around 450F, it burns really, really inefficiently at that temperature, and instead sends a lot of unburned particulate up the flue. Insulating the fire does a couple things: More complete combustion = more total heat available Holding the heat = less active combustion needed to maintain the temperature = slower but still efficient burning Less active combustion needed = less airflow = less hot air going up the chimney Basically, if you get the firebox up to complete-combustion temperatures (1000F), you still get plenty of heat coming out to the surface of the stove to warm the house, and you can limit the rate of hot air going up the chimney to keep that heat in the stove and being released at a more helpful rate (no one wants 500,000 BTU/hr for just one hour). As an added bonus, the firebrick protects the surface material from the crazy hot firebox temperatures, which means the steel or cast iron frame will last much longer. Older stoves often didn't have firebrick, but they were called smoke dragons for a reason - they would burn at lower temperatures without secondary combustion. Adding firebrick and secondary combustion roughly doubles the amount of heat you get from the stove. More on reddit.com

August 15, 2022Fire bricks VS regular bricks?
Just some info from my recent experience that at first was frustrating to me.
I searched google for fire bricks, and refractory bricks. Even Wikipedia wasn't much help.
There is more than one kind of "fire brick." My city has a brick manufacturing plant. I called them and asked if they sold fire bricks. They said that they did but they didn't sell to the public. I spoke with the guy a little while asking questions and once he knew I only wanted 5 or 6 bricks he said he would just give them to me. They ended up being bricks for the inside of a fire place. They are hard and heavy, but I guess they can take the direct heat of being in a fire, where as regular bricks will crack and spall when heated and cooled in a fireplace environment.
So recognizing that these were not the brick I was looking for, I called a local ceramics/pottery store that has classes and sells supplies too. I asked for "bricks that go inside of a kiln" and they said they had them. They sold for $5.99 ea. They called them "soft fire bricks." I ended up with 6 of those and I'm using them for my small propane forge.
For anyone else looking for these bricks I hope to save you some time and frustration. You are looking for SOFT fire bricks.
The hard ones would be good for making a pizza oven though, which is another of my projects.

Common Brick vs. Fire Brick: What's the Difference? - Poughkeepsie NY - All Seasons
July 19, 2023 - Most likely, you’ll find that the firebox – the component of the fireplace system in which the fire is actually made – will be made from firebrick. The rest of the chimney will likely be composed of cement block or common brick, while flue tiles lining the exhaust flue. Utilizing different types of bricks according to their strengths maximizes a property owner’s resources and the function of the construction project.

So my understanding is that the fire brick reflects heat back into the fire box allowing for a hotter burn, thus more efficient. But with that said, isn’t the goal to get the heat out of the firebox and into the room? Doesn’t reflecting the heat back into the fire box just cause it to go out the exhaust? Also is it bad to not have fire brick in my stove? My house had a wood burner in the basement when I bought it and I’ve been burning in it for about 3 years now. I love it and it’s awesome but it only has firebrick about half way up inside the fire box, is this bad? Lastly, is all fire brick created equal? If I were to buy fire brick is there a spec or a brand to look out for?

Refractory Brick Vs. Fire Brick: What is the Difference?
July 5, 2023 - Fire bricks, on the other hand, are primarily composed of clay minerals and alumina or mullite in lower quantities · Thermal properties: Refractory bricks generally have a higher thermal conductivity as of their higher density · Application-specific performance: Refractory bricks are designed for specific high-temperature applications and environments, offering better performance in terms of wear, corrosion because of direct contact with the corrosive media, and thermal resistance.
