how? they’re in a tank

Some of which are probably only a bit stable and so only exist in a mixture

There’s a metastable phase somewhere out there and change of the most stable solid phase between 4-hydrate and 6.5-hydrate

did it ever?

What you’re describing are different crystalline phases of pure compounds, but this does not give you new minima, you need some new compound to form for that

Here is a more complete chart https://chemistry.stackexchange.com/questions/165279/details-of-what-actually-happens-in-cold-sulfuric-acid-between-80-and-90-what

In normal cases you’d see two curves going away from pure compounds downwards to a common minimum, which is eutectic point. It’s generally only vaguely predictable, but always monotonic
