Tunisian guy revives ancient methods to extract pigment from seashells

The Tunisian guy, Mohamed Ghassan Nuwayra, was able to bring back the ancient way of extracting pigment from seashells that have been vanished years ago. It is a process the peoples of the Mediterranean followed in different eras such as the Canaanites and Carthaginians. This unique purple color is one of the most expensive types of pigment in the world due to the effort and resources required to produce it.
