Dave,
Check with the folks at Harbison-Walker (formerly AP Green) and make sure the
bricks are the LOW iron content variety. I bought some AP Green bricks once
and found out later that they were not the low iron type and would have
problems
in a reduction environment. I did not use the bricks in my kiln and got
most of my
money back (restocking fee you know).

Greenlite 23 are good bricks.
Low iron, about the same price as G-23's.
In fact, the last time I was at AP Green, a couple of years ago,
they had a lot more Greenlites than regulat IFBs.
They are made by a different process. If you look closely
they are made of short cylindrical pieces, compared to
G-23's, which just look like a mass with lots of holes.
I used a couple of boxes of Greenlites in my kiln, as a test to
see how they hold up over time, particularly 'breakining-in-two
resistance'.
It's too early to tell. The bricks are coated with ITC and the kiln is
a cone 10 wood kiln - after 1 year, all the bricks are still in perfect
condition.
