I know that concrete retaining wall stones will eventually crack (or
worse) if I use the to build a fire ring.
So I will use brick.
Is all brick suitable? Must I buy "fire brick", or will anything work
since it's been in a kiln?
Think about it... why would such a thing as firebrick even exist, if "any old
brick" would do?
To answer your question: No, not all brick is suitable. If it's going to be in
contact with fire, you need firebrick. Unless you don't care if it only lasts
a couple of seasons...
That sounds good, even like something I would say in response to the
OP, until someone else (you) said it and my usual suspicion and
combativeness took hold. Then I could immediately think of reasons.
It would exist so they could charge more money, so builders could
Or maybe they don't exist and they just make the same bricks, with a
different pattern, and call it firebrick, so they can charge more
money for it.
I'm sure someone can think of more.
When I was a kid, my father brought home some
insulating fire brick from the steel mill. The
things were as light as foam and the same size
and shape as a regular brick. I had loads of
fun pretending the bricks were heavy and throwing
them at various people. Of course the light bricks
would simply bounce off like "Nerf Bricks".
I have also had loads of fun with the empty
plastic display cases for automotive batteries.
The empty case is very light, but when tossed at
someone, produces quite a reaction. What a way
to punk someone. Interestingly enough, the prank
won't work as well on someone who has no knowledge
of those "real" items for obvious reasons. It's a
case of ignorance working in their favor, darn it.
Everyone knows to put nitrogen in the new style tires. Just do not mix the
nitrogen and regular air. The added oxygen might cause an explosion :-)
There should be a warning sign posted at the fill it yourself air stations.
I wasn't suggesting that one didn't need firebrick. He absolutely
I was saying that the argument, "Why would there even exist firebrick
if we didn't need firebrick?" is not as good as it sounds at first.
And I wasn't just being gracious: It's exactly the kind of argument I
would often suggest.
That's because it IS a different kind of brick. But if it were the
same brick, just marketed to people as firebrick, in order to charge
more money, then it might well weigh the same.
I wasn't talking about the bricks but about the argument.
Clay brick may spall on you, perhaps even pop chunks off.
I do have an outdoor fire pit made with concrete pavers that is doing
fine. I am still careful to bring the heat up slowly to boil out any
moisture that may have accumulated in them
