galvanized metal?

PhilOsh

Is there a problem using a galvanized metal framework inside the BGE to raise the cooking level up into the dome? Are there fumes or byproducts or whatevers released from the galvanized metal when the heat in the BGE gets intense?
Any thoughts on this out there?
Thanks,
Phil

Phil,

Oh oh! This is always a lively one :laugh:

Toxic fumes are released from galvanized metal, when it is heated. This is normally considered a respiratory problem, but I really don't think I want the zinc on my food either.

I did not look up the temp that causes a problem, but it is easy enough to get fire bricks or stainless that I do not see the worth of using galvanized metal.

oh no, here we go...

gonna let this one go to see how looney it gets, steven. kinda sick of typing it. :laugh:

just gonna toss a couple gems in there saying that "zinc" by itself isn't toxic (diaper cream, zicam, anyone?)

and if it is possible to get the metal to welding temps (which is what's required), then of the two, stainless steel would be far more dangerous. ...and no onw worries about stainless in an egg (nor should they)

how's that for starting trouble?

PhilOsh

Sorry, I didn't know this was a sore issue. I am curious about what temps are needed to release anything from galvanized metal.

ooooh Boy!!!!

zinc melts a 788F

Humphrey Chimpden Earwicker

yep.

not the issue.

Little Steven

Phil,

Nothing to be sorry about. Sit back and enjoy :laugh:

Steve

fishlessman

yep, not the issue with fumes but now that its dripped off the carbon steel your back to a carbon steel rusty grill :laugh:

Humphrey Chimpden Earwicker

that is true. like a porcelain coated grill. ..not for long.

i just think the entire issue (fumes from metals in an egg) is a red herring. because no one is apparently concerned with the VERY deadly CO which pours out of the egg every single time, during every single cook, in every single egg

and of course, even if zinc fumes were possible, you could directly inhale them every single time without long term or deadly effects.

not so stainless

and again, stainless is not an issue either, just sayin.

you can buy galvy barrel cookers, and galvy parts for gas grills, by the way.

I think you should just "Buck-Up" and take it head-on for the thousandth time! :laugh:

Humphrey Chimpden Earwicker

the MSDS warn against welding temps, not merely melting.

even so, if you somehow got to those temps, and it gave off gasses, you'd have to inhale them, and you'd be inhaling them along with carbon monoxide, which is your real concern. avoid inhaling fumes, and you won't inhale the zinc fumes (which aren't there anyway).
see? :laugh:

I avoid anything that has to do with electrodeposition, aliens and certain numbers.

Humphrey Chimpden Earwicker

too late. already changed it

Billy Grill Eggster

Not a sore point, but wait for the full time employed to get home.

The Naked Whiz

When welding galvanized metal, zinc oxide fumes (not zinc metal) are given off and they are toxic. I did a quick search and found one reference that cited something like 900°C is where fumes are formed.

The Naked Whiz

The problem is zinc oxide, not zinc metal.

Humphrey Chimpden Earwicker

airborne/inhaled zinc oxide, too


zinc oxide is a common ingredient in paints, sunscreen, and diaper cream

ive had galvey poisoning a few times in my life, you get sick before anymore damage occurs and you go find some fresh air. it does melt at 788, so why spend the money on something that isnt going to last in an egg ;)perfectlty fine in a metal style low temp grill, but in an egg once you get it hot the zinc metal is gone and your left with just rusting carbon steel. i dont think you could get it up to the fume stage temps unless you had a big power feeding fan on the intake, even then you couldnt get your face near those hot fumes to breath enough in, it will be hot hot hot :laugh:

Humphrey Chimpden Earwicker

"toxic" doesn't mean lethal, though.
not even dangerous, really, unless you reach some ridiculous level of exposure.

by which point, again, the CO would have killed you long before....

fume fever from zinc causes non-fatal flu-like symptoms, which generally clear up in a short time.

if you had an environment where the zinc fumes were being given off, and decided to use stainless instead, you would be at risk for exposure to chromium fumes, which are very dangerous

the zinc-in-a-bbq myth is based in reality, and that's why it is so tenacious. "based-in-reality' doesn't mean it's realistic, however. :laugh:

PhilsGrill

Not an issue ever in the egg.

Humphrey Chimpden Earwicker

anybody using a raised grid at 800 degrees?

Fidel

Fits your persona much better

Humphrey Chimpden Earwicker

Thanks, Citizen

Phil, I think the issue is some homespun accessories.

Little Steven

I did a flank at 1000* couple of weeks ago. Had to drink a quart of milk to get over the nausea...no wait, that was on the cast iron grid :laugh:

Humphrey Chimpden Earwicker

yes. but his point is still correct. :laugh:

jeffinsgf

You are correct. I had drifted off with the tangents. He answered the original question concisely. Just not used to that.
