Title: Food safety regarding bricks, fire bricks, pottery shelves, etc.
Post by: edhead35 on February 27, 2014, 04:34:42 AM
Having seen many clever people come up with homemade solutions to everyday problems, we have also seen some bad solutions too. An example of this would be doing a lobster boil in a galvanized trash can, which is extremely poisonous.


When using red bricks, fire bricks, kiln shelves, etc., has anyone found any supporting documentation on the food safety of these products? I ask because you never know what you are getting in some cases. You could be getting lead glazed cookware from Mexico or pressure treated charcoal.

 Can't speak to red brick, pottery or pottery shelves, but I do know that firebrick, even at lower smoking heats carries & retains MUCH more heat than it's surrounding environment.....

Below are 'Turds that were sitting over the firebrick prop-up ~~~>

Anything touching, or very near the brick, will pick up, as a guess, maybe 75~100% again of the surrounding temprature.....puts a lower smoke @ 500 degrees......I believe hot enough to kill anything bogus.........

Pizza stones are usually run real high also, my own personal speculation would go along with 'hot enough' on those also........

Now, these are speculations & not scientifically proven stuff......so I'm gonna go lookin'....... 8)

 Clemson Univ. on a wide variety of cooking surfaces.......

A pretty good coversation about such items & the use of clorine (in very small quantity dilutions) as a disinfectant

http://www.potters.org/subject17367.htm

I believe it's 5~7%, but I'll double check to be absolutely sure.......

How can you tell which firebricks are resisting heat and which ones are made to absorb and retain heat?

Throw them on a fire- if they are hot to the touch in a few minutes, they absorb heat. If they are cool, they resist heat.

JUST KIDDING. PLEASE DON'T DO THIS.

A recent thread had some good discussion regarding this:

Meaning from this:
"Anything touching, or very near the brick, will pick up, as a guess, maybe 75~100% again of the surrounding temprature....."

That would mean the food touching or near the firebrick.......I've always assumed firebrick was meant to retain & enhance the heated environment..... & double as an insulator toward the outside environment...ever since high school ceramics.....
Don't know of any that would remain cooler than what they're exposed to.......but there may be some insulating types.......ceramics are all the rage nowadays !!!

 Thanks Mac  & Thanks to G$ for the info in the link !!!

The ones I use for propping up grates must be 'conducting' type.....they get HOT !!!

heavy firebricks will heat up and retain heat

light, porous fire bricks and kiln bricks will reflect heat and stay cooler.


as for food safety, just use a good brick. nothing glazed or painted.
Most pizza ovens are made with brick and its usually not a special food grade brick ;)

Regular bricks can explode. I would consider that unsafe for food.

I've been using what used to be tan colored paver bricks to support my second grate when I do pizzas. They aren't very big and are black now. No abnormal effects.... Not yet anyways

i really don't think regular bricks can explode, at least not under the circumstances provided by us

They might become brittle. They might even crack, but I really don't think there's a danger.

I've used both, but for now I'm sticking with regular bricks (because every house in socal seems to have a pile of them laying around somewhere...)

I just like the fact that someone says these might be toxic to cook on, then buckie chimes in and says I don't know about safety, but they cook the shit out of these turds and shows a big picture of meat sitting all over these bricks.....and if ever saw a picture of Buckie you might be nervous about those bricks......

 Oh Brian......the meat's not sitting right on the bricks.....that photo may have been a bit decieving

 See:

And here you can see I've learned my lesson & the food isn't directly over the brick......

Those 5 'Turds were a curious snapshot in time.....the only time I ever put food over the brick & burned it...... 8)

I've been using regular red bricks (clay I guess) wrapped in foil, for several months, as a zone divider.
No cracking at all.
I have some fire bricks, wrapped in foil, I'll be using today. Not sure they're heat retaining or reflecting tho.
Just received a Cordierite kiln shelf I'll use as a pizza stone.

By that same token, it's like 12,000 pieces of bacon.....How is this man still  alive!  If the exorbitant amount of bacon hasn't killed him those fire bricks won't do shit!   Buckie would you have me for dinner if I was ever in your neck of the woods?

Post by: Durangler on March 01, 2014, 06:46:46 AM
That's only 24 - 500 count boxes of toothpicks.
Then figure 12 slices of bacon per pound & 2 turds per slice, that's only 500 pounds of bacon!  8)

 Oh, You Bet Cha (Y. B. C. ) !!!!!

The place is tiny, there's way too many Webers to even allow for a decent patio table setup, but we'll figger something out........ 8)
I'm broke as hell, need to get back working pretty soon, but there's a ton of stuff in the freezers.....brisket, tri-tip, ribs, pork butt, probably even some bacon (!)

BTW......I had to go get toothpicks to do up the stuff for the meetup @ Winz's place last weekend  (Feature length film @ 11) & that put me over 14,000........ :o 8) :o
Now I didn't eat all of those, by any means, people really like these things.....moinks, choinks, 'Turds of all kinds......bacon wrapped doughnuts, etc.


 Now, back to our regularly scheduled food safety programming.........  ::)

 The one up on the bench to the right is a little Char-Broil the wife got to make up a display about summer fun at  her work.....the covered one up on the rack against the fence is a Happy Cooker.....the lid went to MacEggs for his full-sized UDS, the internal pan went to Craig, 'cause it was his 'parts grail'................ ;D
