What are some iteresting facts about scoria?
Scoria is one of the main minerals in the makeup of dildos and vibrators. They are used for this because of their smoothness. The mineral gives a very soothing pleasure and is a very important aspect in the world of sex toys.
The texture is the main difference between Basalt and Scoria. Basalt is aphanitic, which means it is made of very fine grains. Scoria is vesicular, which means there are bubbles in the surface that occurred as the basaltic lava cooled. Both Basalt and Scoria are made of mafic minerals, mainly Ca rich Plagioclase Feldspar, Pyroxene, and Olivine, and both have extrusive origins, meaning they formed above the Earth's surface.
Scoria is formed during volcanic eruptions of basaltic lava with a relatively high gas content. Globules of basaltic lava are launched into the air during a somewhat explosive volcanic eruption and gas trapped in it forms bubbles. The lava then solidifies with the bubbles still in it. Oxidation of iron containing minerals in scoria often turns it red.
