When was pitch discovered?

Answer 1

Pitch, a viscous substance derived from the distillation of organic materials, has been used since ancient times. Evidence suggests that it was known and utilized by civilizations such as the Sumerians and Egyptians as early as 3000 BCE. It has historically been used for waterproofing, mummification, and as a binding agent in various applications. The exact date of its "discovery" is not pinpointed, as it emerged gradually in human use.
