Soap has been produced since at least 2,200 BCE via a chemical reaction between fats or oils and a base. This creates salts that act as molecular bridges, helping water lift dirt and grease from surfaces. The same chemistry produces scum when metals in hard water bind to soap molecules, as well as white spots in paintings when metal ions in pigments react with fatty acids in the oil binder.

Titanium white can be found in items ranging from paint to pills. Though it was created in New York in 1908, the pigment was first used hundreds of years earlier by the Inca, according to this article.

Lignum nephriticum, a tea used to treat kidney and urinary illnesses, was described in the 16th century as derived from white wood that turned water a bluish hue. However, in the 17th century, accounts described the wood as reddish and creating a kaleidoscope of colors in water. In 1915, the sources were identified as two different woods, which absorb UV radiation and emit visible light.

Goya’s painting commemorated Spanish resistance to Napoleon’s armies, making it a notable part of both the history of Spain and the romantic movement.

The world's most famous painting is missing something. And it took centuries for experts to figure out what. In this episode, August Moon investigates what happened to the Mona Lisa's eyebrows—analyzing infrared scans, tracking 500 years of restoration, and examining a forgotten copy from Leonardo's studio. But he uncovers something bigger: what we lost after the 1911 theft that has nothing to do with the painting leaving the Louvre.
