the mineral that paints your sunscreen and your spaceship the same blinding white
means Rutile is the most common natural form of titanium dioxide, a mineral that crystallizes in needle-like, often reddish-brown crystals and is the chief ore of titanium.
from From the Latin 'rutilus,' meaning reddish or glowing golden-red — the same root that gives us words for ruddy, fiery color. The mineral was named in the early 19th century by the German geologist Abraham Gottlob Werner, who noticed the deep red tint in its translucent crystals; the name caught the blush of the stone, long before anyone knew the brilliant white powder hiding inside it.
