Es Tint is a small property where Lloret's fishermen went until the 1960s to dye their nets, using a liquid produced by boiling water and pine bark. This was when nets were made of hemp, esparto and, later on, cotton. The nets were dyed by means of an ancient technique used throughout the Mediterranean, which consisted of soaking the nets in the liquid previously boiled in the cauldron until they were well impregnated. They were then wrung and put out to dry on the beach. The dye served both to increase the durability of the nets and to camouflage them in the sea.
