What is mother of pearl?

Mother of Pearl

Mother of pearl, also known as <a href="https://www.wikiwhat.page/kavramlar/nacre">nacre</a>, is a shimmering iridescent substance that forms the inner layer of the shells of some mollusks. It's highly valued for its beauty and is used in a variety of decorative and functional applications.

Composition and Formation

Nacre is composed of alternating layers of <a href="https://www.wikiwhat.page/kavramlar/aragonite">aragonite</a> (a form of calcium carbonate) and <a href="https://www.wikiwhat.page/kavramlar/conchiolin">conchiolin</a> (an organic protein). The way these layers are arranged creates the iridescence. The thin layers interfere with light, causing it to diffract and produce the characteristic shimmering colors.

Sources

Mother of pearl is harvested from various mollusks, including:

Pearl oysters: Primarily used for pearl production, but also yield valuable nacre.
Abalone: Known for vibrant, colorful nacre.
Freshwater mussels: Commonly used for buttons and other smaller items.
