Product Information

Ulexite is a desert mineral that combines calcium, sodium, water molecules and boron in a complicated arrangement.
It consists of thin crystals that act like optical fibers so that if you lay it on a newspaper or other printed material, the printing appears projected on the upper surface.
Yet despite its transparent appearence, if you look at Ulexite from the side you will see that it is not transparent at all! This phenomenal optical property will astonish you and your students. Also known as TV rock.
