Hi Mitchamus. Why did you want the bricks from Darley's? They are only about 40 mins from where I live. Are they recommended? Cheers.

only because the plan I used recommended 26%(??) alumina bricks, and my local supplier didn't have them - only the 42% - but Darley's did.

I probably should have tried the yellow pages for another supplier, but I just used the internet.

My local brick supplier had firebricks, but they wanted $8 each for them.
I asked if they had made a mistake with the price... twice... but it was true. Not sure what they thought they were doing.

Realistically, the higher alumina content doesn't mean that they hold the heat more or anything like that, but just that they can withstand higher temperatures... and unless you're going to use some kind of forced combustion (bellows, compressed air etc) or use coal, or liquid oxygen , you wont be able get your fire hot enough with just wood to do any damage to fire bricks.

I have never seen a Darley's brick except in pictures.

Hey guys,

I have moved this to Getting Started. I think it will be more useful there.

Mitch, for your info, Darley's are 1900kg/m3 vs 2230kg/m3 for your Chinese 42%'s. Denser brick holds heat longer once it is heated up.They are theoreticly still a medium duty brick as super-duty is 45% and up.
