:If you find a hard white rock, it's probably quartz; very common where I live. Decorative white pebbles? Quartz. Clear, pretty crystals might be the same compound, but they had to be pure to start with and they had to cool really slowly.

:Well, it helps if you play [https://dwarffortresswiki.org/index.php/DF2014:Stone#DF_Geology_and_Geology_in_Real_Life Dwarf Fortress]. Olivine is one of the green stones (that only really has use as building material/decoration, but makes an impressive megaconstruction mayerial if you find enough of it to make that worthwhile), unlike quartz which features as raw 'gem clusters' more typically cut for decoration of mugs, crossbow bolts, etc. Of course, IRL, quartzes are ''so'' ever-present that they are very easy to forget ''except'' as fancy crystals (either for timekeeping in watches or timewasting in crystal healing) and as such you can actually find them almost anywhere (if you're not stuck on a desert island).

I resemble this comic ... I specialize in probability. Does everyone know that probability=1 means 'certain'? ... I'm not certain ... (Unsigned by 162.158.167.245) | I resemble this comic ...

I got the idea that ''both'' Cueball and Ponytail were geochemists, rather than Cueball being just an average adult.

Seemed like the examples of substances the average person might reasonably know the chemical formula for should include a mineral. Halite seems likely (though that name is probably less familiar than table salt). Diamond and graphite were the only other minerals that I could think of that many would know the formulas for (C). Chalk (calcite) seems possible, but less likely. Any other suggestions (or even better, any citations to research)?

:technically water in the form of ice is a mineral. But including salt is a good idea. And I'll look for citations.

:I would expect lot of people would be able to name "formula" for more than several elements, along with having some idea how they look OR where they are used. Not as common knowledge as water and salt, but assuming they had SOME chemistry in school, this would be more likely to be remembered than compounds. Also, speaking about diamond, I suppose average people would claim that formula for coal is C, although I suspect that chemists would say that's not correct. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 02:16, 13 August 2021 (UTC) | :I would expect lot of people would be able to name "formula" for more than several elements, along with having some idea how they look OR where they are used.

::I probably wouldn't have been able to tell you the chemical formula for salt off the top of my head, unless you prompted me with "sodium chloride" (but even then, it's a toss-up as to whether I'd get the elements right). I studied chemistry for five years at secondary school and got good grades, but you'd be amazed at how little sticks when you have absolutely no need for it in day-to-day life. --[[User:Enchantedsleeper|enchantedsleeper]] ([[User talk:Enchantedsleeper|talk]]) 08:56, 13 August 2021 (UTC) | ::I probably wouldn't have been able to tell you the chemical formula for salt off the top of my head, unless you prompted me with "sodium chloride" (but even then, it's a toss-up as to whether I'd get the elements right).

Friendly local geologist here, I made some changes especially to the third paragraph because a lot of the science was confusingly written and not really correct (desert islands tend to be made up of primarily silicates? Even volcanic ones. Basaltic rocks have silica in them too, that's what olivine is) I wasn't sure what to do with the second paragraph. It seems a bit unnecessary to talk about quartz so much, since it isn't that relevant to the comic. I was thinking it might be good to have an explanation of the difference between sili'''con''' the element, sili'''ca''' the mineral structure, and what all these minerals actually are might be more relevant? Or at least we could put up what some of the chemical formulas are for quartz and olivine and maybe like albite, anorthite, microcline to represent the feldspars.

:I thought (in a prior edit, by someone, may have lost its clarity in subsequent edits by others but I don't have the patience to cross-compare it all) the point was that coral-sands are not silicates, so your classic "lump of 'sand' poking out of the sea" is sparse of the stuff you might want to thrown your rock at. And any suitable rocks, unless you go diving down in the surrounding oceon to rumage beyond the living coral to the seamount/extinct-and-eroded-volcano it has been growing upon. That said, there's a lot of variation out there, so maybe I'm thinking of a too-narrow subset of examples.

The explanation mentions carbonates as a notable exception to silicates, but sulfate minerals are widespread and economically important (and therefore ubiquitous in their finished forms -- e.g., gypsum -> plaster or drywall). Might deserve a mention?
