On Sand and Silica

[Flashlight237]

So we don't have a listing for sand or silica aka quartz despite sand being pretty fricking common. Sand is basically these grains that you find in deserts and beaches, the former being more useful as the common feat for burrowing through the ground very much requires it.

The values for sand are as follows:

Fragmentation: 96.3 kPa (0.0963 j/cc) (Google extracted that part from a paywalled part from here: https://link.springer.com/article/1...le, under the normal,clay samples is 56.4 kPa.
V. Frag: 172.36 kPa (0.17236 j/cc) (https://www.researchgate.net/public...gation_of_the_Strength_of_Carbon-sand_Mixture )
Pulverization: 1 to 1.2 MPa (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6835750/ )

Silica aka quartz, on the other hand, is weird... So, it is commonly agreed that quartz has a tensile strength of 48 MPa, equivalent to a shear strength of 28.8 MPa using the 60% rule.: https://www.qsiquartz.com/mechanical-properties-of-fused-quartz/

https://technicalglass.com/technical-properties/

On the higher end, one source that, imo, doesn't seem very trustworthy puts it's shear strength at 70 MPa: http://www.mt-berlin.com/frames_cryst/descriptions/quartz .htm
Yet AZOM puts it's high-end tensile strength at 155 MPa, which is equivalent to 93 MPa using the 60% rule: https://www.azom.com/properties.aspx?ArticleID=1114

As for compressive strength, every source I've seen for it lists it at a whopping 1100 MPa! Like, wow! Anyway, here are the destruction values for quartz itself:

Fragmentation: 28.8 j/cc
V. Frag: 70-93 j/cc
Pulverization: 1100 j/cc

Since these materials are both common af, should we have these added to the destruction values list?

Common in abundance, maybe. Common in actual destruction values for feats that don't involve heat? Not really. I mean, who punches sand with the intention of breaking it into fragments LOL. Sand is for punching bags.

I mean a lot of desert creatures burrow in the sand and we have byrrowing as a common feat. Tower from House of the Dead 2 and the Sandbelching Meerslug immediately come to mind, plus there's a yellow Blaarg-looking thing in Super Mario 3D Land that burrows through the sand trying to eat you. Those are just three of the many examples out there.

Also, nobody punches soil with the intention of breaking it into fragments either and yet it's hanging out in the destruction values table, so kind of a moot point there.

Eh, not really sure if those really count TBH, for all we know they could just be displacing the sand.

Thing with soil is that it's too soft for fragments to be left behind but craters? Now that's a different strory.

Same can be said for sand, I mean deserts and oceans are equally caked in sand as most areas are with soil. It can even get as deep or deeper than how deep we expect soil to be (in soil's case, about 6 feet): https://en.m.wikipedia.org/wiki/Erg_(landform)

Sand. The final frontier. No wait, that’s space. Never mind. Sand is still really cool though, really! Keep reading. How deep is the sand in the Sahara? The Sahara is the world’s hottest desert though it’s not the biggest. It’s third in size. The two biggest deserts are, somewhat...
