Stainless and SIlicon baking forms.
Stainless and SIlicon baking forms.
(OP)
When greasing aluminum cake pans the paper towel gets a dark residue on it. I rather expect this aluminum oxides and I often use wax paper to avoid food contact.
Well today I get a very dark residue while greasing my stainless cookie sheets what is it and why?
Is there any hazard with silicon cook sheets contacting food?
Thanks for any insights!

RE: Stainless and SIlicon baking forms.
Are you sure you are using the word silicon correctly? Silicon is an element, a semiconductor, used for making microchips. Silicone is a generic name for a group of silicon-based substances, usually elastomeric polymers like polydimethylsiloxane.

The other possability is that hte sheets have been rubbing against each other and there is a little bit of metal wear residue coming off of them.
Baking molds of silicone rubber have become popular. I would bake them once before using them. I would also watch and when they begin to crack or tear I would pitch them.

And yes I meant Silicone! Thanks for the correction.
EdStainless; This is before heating so I don't think it is varnish. We do definitely see the varnish after baking.
No rubbing has occurred because of the sheet shapes. (they can't nest)
I was concerned that the interstitial material that gives elastic materials their flexibility(I forget what it's called){the stuff that slowly leaks out of keypads on our remotes to render them useless} might come out of the Silicone sheets and render us useless.
Thanks for the direction.
swall; Yes! Muffin and cup-cake forms of Silicone and actually flat sheets that you can line cookie sheets with to avoid having to grease them.

RE: Stainless and SIlicon baking forms.
I have seen what you are describing. Likely this is a combination of aluminium oxide, aluminium particles, and other foreign particles (food, dirt, etc.).

RE: Stainless and SIlicon baking forms.
You are correct in assuming that 'things' come out of the silicone. But these materials are used for a lot of biological and medical applications. I wouldn't be too worried.
