i recently came across some free bricks and was wondering if anyone has
any info about them. i have searched the archives and the net to no avail.
any help would be appreciated. they are stamped LFB ( i know this is
louisville firebrick) one has "derby" the other "louisville firebrick". i
am thinking that the temp/duty is different or maybe the year they were
made. they came from a chimney that was TORN DOWN in the 50's. they are in
remarkable shape though and i intend to use them at the top of my woodkiln
chimney.they are 2 1/2 " series straights
i also have some that are stamped "mexico-mo rec"also a 2 1/2 straight
and "woodland" a wedge.
the ones i am most curious about are the empire 3x12x30.got 6-all in
pristine condition. need to know temp./ duty rating. anyone have any info?
thanks,
leo

If you are only using them for the top of the chimney, they will
probably be plenty refractory. I used low duty fireplace bricks for the
upper chimney and they are doing fine. Perhaps you could include a
brick, or a piece of one in a ^10 firing, to see what happens to it?

The "mexico-mo rec" is an AP Green brick from Mexico MO, a "high heat
duty" refractory. It will take ^10 with ease.

Unfamiliar with that one, but if it's a wedge with a name stmped on it,
I'd bet it is "high heat duty" also. Another one to fire in the ^10
test.

Wow, those are BIG! Empires are an AP Green brick, again "high heat
duty", with a pyrometric cone equivalent (PCE) of ^32. Damn fine stuff!
I have a few of the 2x12x24 kind. They're great for floors. Let's hear
it for the Brickmakers, we LOVE our Bricks!

Take on brick on edge(2.5 x 9" face facing up). Stack another on top
of this also on edge but at right angles to the first. Now the two
bricks have a 2.5 inch square mating face. FRom the top thy form an
'X'. add four bricks stacked in their normal flat configuration to the
the stack making the second brick "weigh" like five. Fire to cone ten
in reduction and look for deformation at the 2.5 inch mating surface. I
have seen low duty bricks distort with this test and taken it as a sure
sign they will not hold up to cone ten. It would be a more useful test
with ten extra bricks.
But the top of a chimney is not very hot usually.
