Okay, so I was casting a part out of zinc (pennies) on my parent's grill, and on the stir rod, some metal stuck. While I waited for the mold to cool, I subjected said metal to a propane torch. It burned and wreaked, and I set it down to inspect the mold and when I returned to the stirring rod, there was this weird white translucent solid gel type stuff. I tweaked the curves on the pictures to bring out some detail.

I also noticed this a while back when jolting pennies with a crazy amount of electricity (capacitive discharge). I can't find the pictures of these

Any idea what this might be?

I know about fume fever, and I think I have had it before after burning magnesium, but it was a rather windy day, and I was really bored.


Here is a link with lousy pictures from the electrical discharge material

looks like jizz...

but don't worry... if your parents are in their forties that's pretty standard... just get used to it

Do you have snails or slugs in your yard?

it leaked from the pennies it probly somthing added to them for some reason and when u heated them it leaked out

Obviously "slugs"..................... (H*MO)..............

not jizz, no snail problem, and the pictures in the linked thread occured in my room, ruling out slugs, but fortifying the argument for jizz... but really, not jizz not slug crap.

and there are many slugs in my neighborhood, but not many gastropod molluscs, afaik

Its just some burned stuff. Maybe it had a corrosion-like reaction, forming this mysterious material.
Metal + air + heat = ?

Zinc pennies may contain something other than just the zinc core and the copper skin. If you file the edge off a penny, cutting through the copper layer, and drop it in muriatic acid (hydrochloric acid) you can dissolve the zinc core leaving behind just the very thin copper coat. When you do that there is some black solid that forms as well. I've never been able to figure out what that black stuff is. It doesn't appear to be a copper or zinc compound.

Perhaps that is related to your mysterious white solid?

Is the white solid stuff soluble in anything like water or dilute acid or base? Is it unusually light (low density) or dense enough to sink in water?
