The imitation pearls that are often used in industrial production mainly include plastic beads, glass beads, solid glass beads, and shell beads.
1, plastic beads
It is a bead made of plastic, coated with pearl pigment, which looks very beautiful, and is characterized by a light touch.
As early as the 17th century, glass was used to imitate pearls.Joquin, a French rose manufacturer, discovered that the water after washing fish left a shining substance, and used these substances to concentrate into pearl pigments. 1656 Zu Kun began to imitate pearls. He dipped hollow glass beads into acid gas to remove the luster of the glass, then used the pearl pigment he invented to paint the inside of the beads, and then put wax or glue to increase the weight of the beads. Imitations often appear in ancient jewelry.
3.Solid glass beads
Also known as Majorca. It is an imitation pearl invented by the Spanish. Because of its fine process, it can be fake and is well-known all over the world. Majorca beads are made of milky white glass with a core, and then coated on the surface. Special glitter film made of fish scales. High-quality imitation beads need to be coated with 30 layers, each layer needs to be coated at a different time, so that light interference and diffraction can occur, and the surface will form a brilliant color. During the nuclear coating process, there are several steps of drying, cleaning and polishing of the immersion liquid. The last step is to use a special chemical immersion liquid, which may be cellulose acetate and nitrocellulose to polymerize organic substances and harden the surface. In order to avoid damage to the product, this kind of imitation beads, which are very similar in appearance to marine culture beads, are often inlaid on modern styles of K gold jewelry, and the products are sold all over the world.
4. Shell beads
Use shells to grind into beads, and then apply pearl paint on the surface of the beads to make shell beads.
