No, minerals are “a solid, inorganic substance of natural occurrence” so a lot of solids are minerals yes, but not all solids.

Any solids that are organic, like wood, are not minerals.

And any solids that are naturally occurring, like Steel or Bronze, are not minerals.

Can a mineral have different sets of chemical elements in each sample of the same material?

I suspect you missed a "not" inthe last sentence.

Wikipedia : "a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form".

So artificial solids (plastic, steel...), or solids coming from living organisms (wood, coal), are - most of the time - not minerals. And rocks are generally a bunch of different minerals stuck together.

Neither steel not bronze are naturally occurring, nor minerals. They are both human made alloys that are not naturally occurring

There can be different contaminats in the same mineral, but generally the chemical composition of a mineral is going to be the same in every version of that mineral. If it differs, it's a different mineral.

As an example, both sapphires and rubies are the same mineral (corundum) with different impurities that change the color.

Doesn't Organic mean "containing carbon"? So would iron be a mineral but steel not be?

To a point. Some minerals form a series where, for example, you might replace aluminum with magnesium or whatever. But a mineral by definition has to have a specific composition or range of compositions. That's what distinguishes it from a rock (which is a collection of [possibly many different] minerals).

Correct. Also, steel is a man-made alloy and therefore not naturally occurring. Same with bronze

Notably, though, this is a definition of convenience, since man-made materials absolutely can show the same properties that natural minerals do, and be studied with some of the same tools.

In geology, mineral must also have crystalline structure. So, obsidian is a natural inorganic rock, but not a mineral, because it's a glass, not a crystal or a bunch of crystals.

They probably missed a 'not'

Which is also why, by definition, ice is a mineral, unless it comes from a freezer.

That would make more sense lol

Comments aren’t loading so apologies if already answered.

Ice is solid water. Water is not a mineral.

Seeing as all elements can be solid depending on their temperature that would have to mean every element would be a mineral, so I can't imagine it to be the case.

Minerals don't have to be inorganic. Evenkite is a rare organic mineral, for example.

A kitchen table is not a mineral. Minerals also need homogenous elemental composition.

Some argue ice is a mineral.

Ice is a mineral when it occurs naturally. Liquid water is not.

Some definitions call for "chemical compounds". So Iron isn't a mineral, but iron oxide is.

Not true in my county... Here ground water is considered a mineral actually.

The necessity of a crystalline structure on the definition seems like an unnecessary restriction imo.

Ice has a crystalline structure.

Yes, that's my point. I don't see how melting something turns it into a non-mineral.
