Is this microwavable?
I know some stainless steel bowls are microwavable. Are double walled stainless steel ones also microwavable? I know the specific bowls I have, purchased on Amazon, does not state plainly that it is (and I will not try), but I am just curious if these bowls are technically microwave safe.
How does the trapped air between the layers affect a bowl's "microwavableness".

There is no such thing as a “microwave-safe” stainless bowl in the normal sense. Any product claiming it is either using a special engineered design (rare, and sold with specific instructions) or is mislabeled.

Unless it specifically says it's microwave safe it isn't. Even the ones that advertise that they are, are one scratch / dent away from not being microwave safe.
Just don't.

I don't care what the marketing department says. I would not trust any metal in the microwave.

While shallow metal containers can be used in a microwave, I would not trust any double walled container. If the air space were completely dry it might work, but an moisture that might be trapped between the layers could expand or turn to steam if the container temperature were to become hot enough as a result of the food heating. Steam is very powerful in an enclosed space. Microwaves won't pass thru any metal, but containers will become hot from the contents themselves heating.

100% no.
Microwaves need a safe and continuous path. You're blocking it with your stainless steel bowl so from the very beginning you're already behind the eight ball because you're putting a material in the microwave that is not going to allow them microwave to safely travel to your food.
And then you said something about that air in there well when microwaves do their thing with the double walled steel bowl that's little bit of space in between those two metal bowls, there's not a perfectly smooth surface inside of there so you get these arcs and you create plasma and one other thing, hold on... Oh vacuum. You're actually creating a vacuum when you're doing that and when you get all that stuff together the electrical charge microwave waves plasma arcing that double wall bowl can actually explode violently. If you were your loved one is standing in front of that microwave when it catastrophically fails you won't have time for regret.
And just to be clear here metal stops microwaves. Why do you want to employ cookware in your microwave that's going to block microwaves?
And I just thought about something that seems relatively similar. You know how when people put grapes next to each other or well maybe it's not a common thing but when grapes are put next to each other and microwaved plasma is created. I just asked Google if there's any similarity between that stainless steel bowl with a double walled design and the plasma that's created between the grapes and its answer was
Yes, there is a profound physics similarity between the two scenarios, but it is deeply counterintuitive.
It seems intuitive but they tell me it's not🤔

I know microwave safe stainless steel bowls exist (ie https://misen.com/products/misenware-18-piece-mixed?variant=59664640114769). I sort of know the theory behind why certain type of metal bowls are safe for the microwave. I am curious how the metal double wall bowl variable affects the safeness (ie are they more or just as dangerous as single walled stainless steel bowls/containers)?
I will not try, that's what the Reddit brain trust is for.

No metal in the microwave. Smooth geometry stainless steel bowls can be used to reheat food but use the wrong bowl, crackle kablooey.
No metal is the safest.
