Aluminum peel melting on baking stone- health hazards?

Hello, everyone,


 


I've been using an aluminum peel to move bread to and from a baking stone and I've noticed that some of the peel's material has been melting into the stone.  I'm wondering if there are any potential health hazards from exposing food to these small flecks of melted aluminum.

Huh? The melting point of aluminum is 933K/660C/1220F. I've never seen a home oven or a baking stone get anywhere near that hot. (And I've never seen any metal flecks on my baking tiles in my electric oven despite using a metal peel all the time.) I strongly suspect something else is going on here  ...the question is what?


Where did you get the peel? How old is it? Could it have been coated or painted or mended or otherwise soldered on? Is there a telephone number you can call and ask what's going on?

(Edited because Chuck just said it.)  If bits of aluminum are scraping off of the peel then they may be ending up in your bread.  Dangerous or not, it doesn't sound very appealing.  If that was happening to me I would get a new peel and save myself the worry.

as Chuck has noted.  It's probably material that has been scraped off the peel by the rough surface of the stone.  I've seen Formica countertops marked by aluminum pans and Formica isn't nearly as hard or abrasive as a baking stone.


I can't answer to the health issues but my guess would be that the risk of uptake isn't measurably greater than what you routinely encounter by using the peel with the raw dough; i.e., virtually nil.  If you are using any other containers or tools make of aluminum, you are probably encountering more exposure (which is not the same as absorption) from them than you are from some flecks on your stone.  You can read what the CDC has to say on the matter at this site: http://www.atsdr.cdc.gov/phs/phs.asp?id=1076&tid=34

aluminum is soft and will leave a "mark" on many many surfaces.



aluminum attained "fatal if ingested" status in the late 50's early 60's when a well meaning (I'm sure . . . ) UK physician noted aluminum in the brain plaques of Alzheimer patients - post mortem.



it is an inconvenient fact (to the aluminum pan freaks) that since then, numerous studies conducted by numerous famous / national / independent sources have demonstrated / proven that aluminum is not the cause of Alzheimer brain plaque.
but a good rumor shall never die . . .



ps:  you'll ingest more aluminum from pickles, deodorants and toothpaste than you'll ever ingest from aluminum cookware.
