Summary[edit]

Description

Ulexite is a desert mineral that combines calcium, sodium, water molecules, and boron in a complicated arrangement. 

It forms in alkali salt flats where the local water is rich in boron. In rock shops, cut slabs of ulexite like this one are commonly sold as "TV rock." It consists of thin crystals that act like optical fibers, so if you lay it on a paper, the printing appears projected on the UPPER SURFACE, very hard to see on a 2D photo.
But if you look at it sideways the rock is not transparent at all.
