Question:

aluminum form in microwave/oven?

I really need your helpToday I made a lasagna, it was prepared already, straight from the package, in soft aluminum form, frozenI put it to for 30 mins microwave (which also has a functionality as an oven, grill - just 4 various functions/buttons)Then come my boyfriend and is shouting at me that i destroyed the microwaveFacts:1The microwave still works, no smell, no burns.2After 30 minutes it stopped, as i programmed it,Did i mess it up? Is it possible that the microwave is broken and we just have to wait few days to see it? I found in the internet that aluminum forms (not aluminum foil) are safe as long as they dont touch the borders of microwave.Please help me, i really need an answer.N.B No idea what was written on the lasagna packageMy bf put it to microwave and told me to set the program so i never had a chance to see the instructions on the package.

Answer:

You answered the question yourself, 1The microwave still works, no smell, no burnsIf it still works, then you didn't ruin itThere is very little chance that a problem caused by this will be revealed over the next few daysMost commonly, metal in a microwave will either work ok, or the metal will give off sparks, melt, or catch on fireIn these cases, you'll see the effect immediately! Rarely, the microwave generator tube will burn outIf it's going to, it will do so while operating with the metal in the ovenIt's very unlikely to damage it just a little, and have the generator burn out laterJust try not to put metal in the microwave in the future.
That depends on the hazardGenerally, the less reactive metals are the least hazardousGold, silver, platinum (noble metals) aren't generally hazardous and are generally used in implants, jewelry and suchGroup 1 and group 2 (alkali and earth alkali) metals tend to be very reactive Metals such as nickel and mercury can be toxicMetals such as uranium are radioactive, and a bit toxic.
All those mentioned in your question except for Pb (lead) are not hazardousThe metals that make up groups I and II are extremely dangerous/hazardous when in contact with water (release of hyrdogen gas due to chemical reaction makes for explosive results!) Lead is poisonous when large enough dose enters the skinAll those to the left of the zig-zag line which separates the metals from the nonmetals/gases are what you have to look atSome of them are radioactive, extremely and instantly reactive to water, and etcWe take aluminum, iron, zinc, etc products everyday sometimes in form of vitamins or medicines or byproducts of the food we eatHope this helps out some.
If you mean which are not hazardous to ingest , I'd have to say that all metals when ingested in heavy concentrations are dangerousBut many like iron and zinc are beneficial in small quantitiesSome metals are immediately hazardous even in small doses , such as lead and mercuryAnd some have long term implicationsThere are currently studies that point towards long term aluminum exposure as a possible cause for Alzheimer'sStick with the RDA of these minerals and don't eat anything made of heavy metal and you'll be fineOh, if you are afraid of metals such as gold or silver you can send them to meI'll dispose of them properly for you.
Of the metals you listed, only lead is considered a hazardAll the other ones are not really toxic.
