Latest Edition: 20th June
Erika Wright’s Indispensable invention this week is Toothpaste
Early Toothpastes
The earliest existing recipe for toothpaste is over 1600 years old and was recently recovered from the vaults of the Austrian National Library. It had been lying there untouched since it was retrieved from an Egyptian Rubbish dump over 100 years ago. The recipe includes honey, mint, crushed iris flower and salt. For centuries people used chalk, soaps, and even pepper to clean their teeth. Erika talks to Cornelia Roemer, director of the papyrus collection in Vienna.
