Wonder if you could drive on that obsidian, or is it too hot/sharp for any vehicle to drive over that area.

[-] VelvetGentleman@lemmy.world 45 points 6 months ago

Obsidian forms when lava cools very rapidly, limiting crystal growth. The lava pictured above most likely cooled slowly.

[-] Sparky@lemmy.blahaj.zone 13 points 6 months ago

Cool. I guess I used lava and obsidian as synonyms.

[-] MonkderDritte@feddit.de 12 points 6 months ago

That's no lava, lava is fluid, magma too.

Depending on when this picture was taken, it's just the outermost layer that's solid. The lava flows from underneath.

I’ve used Obsidian to take private notes using Markdown. Also thought of this:

My son 🙋‍♂️was SO cute today, he asked me “dad are clouds candy?” 😍 I told him they were water. 💦 Then he asked “Dad, what’s the Earth’s defense system?” and then I remembered I don’t have a son and he asked again with his eyes obsidian black “what is the defense system father”

Loved it, we need more people like you on Lemmy. Keep it weird 🖖

Edit: I use Roam instead of obsidian.

-“Where is Earth’s defense system father?” Intensifies

Love the weirdness

Obsidian is stone glass?

[-] RizzRustbolt@lemmy.world 1 points 6 months ago

Glass is stone glass.

[-] MonkderDritte@feddit.de 1 points 6 months ago* (last edited 6 months ago)

Is silicate glass.

Too hot, but every other time this has happened in the last several months, they've been able to spread dirt and gravel on top to make a temporary road.

[-] Anticorp@lemmy.world 5 points 6 months ago

After some time, you can. But it's going to be molten underneath the crispy exterior for a while. You're going to need some beefy 20 ply off-road tires so they don't immediately get sliced open.
