Bismuth crystals aren’t exactly true minerals, but they show some of the symmetry properties and are really easy to grow. You can buy kits to be able to do this. Do not use a good pot or tongs - you aren’t likely to get them back.
i reblog this in the full knowlege that luka is going to go do this immediately
Must… not… ruin… pots…. making…shiny… bullshit

This is a very rare and awesome find. This is a crab claw that has been opalised in the same way that petrified wood is. Very rare and very beautiful specimen.

Science side of Tumblr please explain how this possible.
It forms when plant/animal material is buried by sediment and protected from decay by oxygen and organisms. Then, groundwater rich in dissolved solids flows through the sediment replacing the original plant or animal material with silica, calcite, pyrite or another inorganic material such as opal.
The result is a fossil of the original material that often exhibits preserved details of the cellular structures.
Hope I have helped.

Oh sure, when nature draws a perfectly triangular cave it’s “a syncline-anticline fold” and “used by shepherds as a shelter since ancient times, but when I do it suddenly it’s “bad worldbuilding.”
whatever just stay out of my hole
