Smithsonian Magazine

Introduction
Did you know that the Inca beat modern science to a major discovery? Way before a metallurgist named Auguste Rossi turned heads in 1908 with a brilliant white pigment called titanium dioxide, the Inca were already using it to jazz up their ceremonial drinking cups. Smithsonian Magazine spills the beans on how these ancient innovators tapped into the Giacomo Deposit for this pigment, centuries before it became a staple in everything from our paint to our pills. Dive into this colorful tale and see how the Inca's savvy use of natural resources challenges our timeline of technological advances!
