Many years ago I was told that higher levels of Ozone in the atmosphere , following a rain & lightening storm .... produces that smell that you described ... and the freshness it reveals . You can almost taste it and I know this because when it's about to snow , I can taste or smell it in the air hours before it begins. Weather or not .. this actually true is beyond my knowledge but I remember using Ozone in an aerosol can to freshen bathrooms and I believe similar products are still marketed presently.

We had that same issue with our last set of pots and pans. A good smack with a rubber mallet works.
I have a hunch they did that because the wife would take the pots / pans from the burner, empty out the food, put the pots in the sink (while still hot) and turn on the water to soak them.
No more of that with the new set, and no more pot wobble.

The odor you get from freshly starting rain is from bacteria in the dust which is stirred up when water hits a ground surface. There are always micro-fine dust particles on surfaces of the ground, grass, tree leaves, etc., when the weather is dry. As the rain hits these surfaces, the bacteria in the dust is stirred and rises, giving you that aroma, along with ozone, etc.

I've had one of those over 40 years ago and I liked it and was impressed with it. I could put my hand on the stove and it would not burn, but the pot next to it would heat up, interestingly, an empty pot would not heat up as well, only the ones with stuff and or liquid in it would!
You had an induction cook top not one with radiant elements. There is a difference.The one Jerry has uses radiant elements. I have one too.
Radiant elements use heat to cook. Induction cook tops use magnetism. That is why you can put your hand on an induction cook top, turn it on and feel no heat. Induction cook tops were nice, but very expensive to manufacture and repair. I know, I was an appliance tech at one time.
Also, you are wasting energy by not using flat bottomed pots and pans on radiant
elements.
Induction cooking, uses electromagnetism to turn cooking pans into cookers (creating heat energy inside the pan itself, instead of firing it in from outside), which cooks food more quickly and safely with less energy.

If it uses magnetism, then how you do you explain it heats up too when aluminum pans are used, or it does not when a steel pan is used that is emptly?

Last house I bought has an induction cooktop. Had to give away several pots because induction only works on some materials (not aluminium or some stainless steel or copper). It works well. Brings water to a boil faster and has safety features that turn it off if there's no pot on the top. The top does get warm because of conduction from the pot, but it doesn't get as hot as the radiant cooktops.
I see that you can buy induction hotplates.

Unfortunately, naming the rain-smell accomplishes nothing but giving it a fancy handle. Says nothing about what it is. The smell is different whether it is over a roadway, in the desert (add creosote bush smell), at a lake, near sewage, etc. I have heard some of the smell comes from the release of dissolved ozone reacting with ambient odors kicked up by the splash of drops. What did the scientists say it was (besides naming)?

Jerry,
Farberware cookware had a raised center in the pots and pans. as they heated up, the centers would expand (aluminum bottoms, stainless steel tops) to make a better fit to the heat source. Aluminum is or was supposed to be a superior conductor of heat.
Gave many Farberware sets as wedding and housewarming gifts, years ago. You might check ionization as the culprit in the odor when it rains scenario. You certainly seem a " man of all seasons..."

These are all Revereware, over fifty years old. Only two of them have the "pointy" bottom. I have some high tech tools (hammers) in the garage that might be able to repair them. :)
Yes, I am a man for all seasons. That why I continue to live where it's hot and cold and snowy. Nice variety.

My elevation here is about 800' above sea level. : )
As for sex and religion, I never participated in any religious service that involved sex. Maybe I had joined the wrong church.

I must say you have some of the most unusual problems. Keep em comming

I'd say time for new cookware. The food in the pot will not cook evenly and make it more likely to burn on the deeper areas.
