What glass is best at resisting acids when dissolving?

[SeekingKnowledge]

Is there a certain borosilicate that resists all types well enough to dissolve rocks in them?

Are there reasons to dissolve rocks in different types of acids to get a different result? Dissolving coal in sulfuric vs hydrochloric for instance, would you get a different residue/result?

Thank you for any help assisting this noob.

Acids do have a common characteristic - they produce H⁺ when dissociating, and H⁺ is an oxidizing agent (mildly strong), but their other properties vary, which often makes one better for a specific task than others.

Silicate glass is in general good for all acids with an exception of hydrofluoric. That's an example of where the 'other properties' come into play.

Thank you for responding. I already have some borosilicate glassware, are you saying I just need specifically a silicate container?

No, I mean "any glass that is SiO₂ based" - which in practice means all of them. Sure, there are differences, but as long as we are talking about laboratory glass (as opposed to "any glass container sold for general public") they shouldn't matter.

Disclaimer: all possible warnings about concentrated acids go here, they are dangerous, corrosive, some are especially toxic and they all require care/proper setup/proper hardware. To avoid the risk: learn the rules, play by them.

Counter ion makes a huge difference. Most sulfates are soluble as chlorides, but a lot of sulfates aren't soluble as chlorides (just to use your example?. This will affect solubility in acid if there isn't another dissolution pathway, i.e. hydrogen gas formation.
