Clément Massi became acquainted with the art of ceramics in his father’s pottery workshop in Vallauris before setting up his own business in Golfe-Juan. His metallic lustre productions were very successful, obtained following numerous experiments that gave excellent quality results where the iridescence involved both the structure and the decoration in a balanced synthesis. The lustre technique was resumed towards the end of the nineteenth century, thanks to the recovery of ancient practices from the past, updated in a modern form.
