titanium dioxide's prettiest disguise, born blue and destined to become white paint
means Anatase is one of the three natural crystal forms of titanium dioxide (TiO₂), a mineral often found as steep, dark, glassy pyramidal crystals.
from From the Greek 'anatasis,' meaning 'extension' or 'stretching out' — a nod to the mineral's elongated, drawn-out pyramidal crystals, which look taller along one axis than its cousins rutile and brookite. The name was coined in the early 19th century by the French mineralogist René Just Haüy, who liked to read a crystal's geometry in its name.
