Byssus

Sea silk is an extremely fine, rare, and valuable fabric that is made from the long silky filaments or byssus secreted by a gland in the foot of pen shells (in particular Pinna nobilis). The byssus is used by the clam to attach itself to the sea bed. Sea silk was produced in the Mediterranean region from the large marine bivalve .

Hopp til: navigasjon, søk. Byssus er hornaktige tråder ( filamenter) av keratin og ulike proteiner som utvikles hos ulike mollusker for at det vannlevende dyret skal kunne feste seg til ulike overflater. Silk is usually made from the cocoons spun by silkworms – but there is another, much rarer, cloth known as sea silk or byssus , which comes from a clam. Villagers stare as I knock on the door of Chiara . What I do care is working with all what originates from the Earth and from Water, without disturbing neither the Earth nor the Water.

Barbatia, live attached by a byssus (a tuft of horny threads secreted by a gland on the foot) in rock and coral crevices. Other species, particularly of the genus Anadara, live shallowly buried in sands and silts. Some species, such as the western African Anadara senilis and the Southeast Asian… Read More.

In Sardinia a very unique and ancient tradition has survived: the processing of byssus. Also known as sea silk, byssus is an ancient textile woven from the beard of various clams, and which appears dark brown until placed under direct light, when it glitters like gold. Although it can be made from a few different mollusks, the beard of the noble pen shell, Pinna nobilis, has historically been the . Scientists at the Max Planck Institute of Colloids and Interfaces have gained the first insights into how mussel attachment fibres, known as byssus threads, are produced in the mollusc foot. They discovered that many steps in this process proceed autonomously, i. She describes herself as a “master of ancient weaving”, because her hands move at the rhythm of a traditional craftsmanship that dates back to the Assyrian-Babylonian culture. Byssal, or byssus , threads are strong, silky fibers made from proteins that are used by mussels to attach to rocks, pilings, or other substrates.

Chiara Vigo is one of the last byssus weavers in the world. Each is attached to rocks by twenty to sixty stringy byssus threads of sufficient tenacity to resist extreme hydrodynamic forces. LIKE barnacles, marine mussels attach themselves to rocks, woo or ship hulls. However, unlike barnacles, which fasten themselves tightly to a surface, marine mussels dangle by a network of thin filaments called byssus threads.

As the Italian Coast Guard watches protectively from the shore, she may dive 1times to produce a single ounce of the fibers, by trimming the byssus from each bivalve with a tiny scalpel. The BBC further describes how she says a prayer before . There is a big confusion and misunderstanding around the concept of byssus. Aristotle would have been the first to give the name byssus to the fibres of the Pinna, so is said. This false attribution is based on a translation error, or more precisely an accent error going back to the 15th century, a very momentous error – at least .

Researchers claim to have unravelled the secret behind the strength of the fine filaments, known as byssus threads, which the shellfish use to secure themselves to rocks. The material is made of a protein that is closely related to collegen, which forms skin, bones, cartilage and tendons in mammals. The fabric of the Face made from sea silk (or byssus cloth). In Poland byssus is produced by the zebra.

The ancient Mediterranean populations, whose lives were tied to the sea, used to produce a golden fabric collected from the sea, the subject of countless myths and legends: the byssus filament. Mytilus galloprovincialis, cDNA.
