Title

Murex snail shells

Description

Used in Greek and Roman times for dyeing togas and in the Middle Ages for decorating manuscripts. The mollusks secrete a yellowish liquid that oxidizes to a purplish red in bright sunlight; each mollusk only produces one drop of colorant so large numbers were needed to produce enough dye for an entire cloth, making the dye was very expensive.
