The Green that Killed

Textile History Series

Last night you went to sleep on your sheets without thinking twice. But do you really know what is in them? For nearly a century, that question was not rhetorical. It was a matter of life and death.

The accident that became fashionable

In 1775, the Swedish chemist Carl Wilhelm Scheele discovered a green pigment with an intensity that nothing in nature could match. They called it Scheele's Green, and it was made from copper arsenite.

It did not take long to conquer all of Europe. It was in the wallpaper of the most elegant salons, in candles, in artificial flowers, in dresses that only a few could afford. It was, literally, the color of the season.

It was also poison.

The seamstresses who handled it daily fell ill young. In damp rooms, the pigment released toxic fumes while their inhabitants slept unknowingly. There is even a theory, still debated by historians, that links the deterioration of Napoleon's health in his final years to the green wallpaper of the room where he lived in confinement.

No one certified anything. No one asked what was in the color they were wearing. It took almost eighty years until the danger of Scheele's Green was widely recognized and only then did it begin to be withdrawn from textile production.

The same question, two centuries later

Today no one will sell you sheets with arsenic. But the underlying logic has not changed that much: we continue to dress our homes and our bodies with materials whose exact composition we almost never see.

That is why certifications like OEKO-TEX® STANDARD 100 exist: they analyze hundreds of potentially harmful substances in every textile, and each valid certificate carries a public verification number that anyone can check on the official OEKO-TEX website.

At Gema, every piece we produce carries that number. We don't show it as just another logo on the label. We show it because it can be verified.
