Shell button, also known as mother of pearl button, is a very old natural button.
Shell buttons are different from resin buttons. They mainly go through seven processes: shell selection, punching and shearing, polishing, grooving, drilling, scraping, polishing and bleaching. In the early days, the power source of the machinery for making shell buttons was the rotation of the pulley driven by the foot pedal. Now this has been completely replaced by mechanization. However, some traditional button factories still use semi manual technology when making shell buttons, which can maintain the natural luster and charm of the shell.
Shell selection: different shells are selected according to the button size and requirements, but the utilization rate of shells is not high.
Punching and shearing: also known as blank taking, it refers to making the initial button blank.
Grinding: place the plane of the button blank on the grinding wheel and grind it evenly.
Button groove: part of the button is removed from the middle of the button, so that the button has a concave shape.
Drilling: drill different holes according to different needs, generally two or four holes.
(such a shell button has basically taken shape, but with the progress of the times, people’s requirements for buttons are getting higher and higher. Therefore, the following steps are required to make the buttons more perfect.)
Scraping: make the pattern of the shell more beautiful.
Polishing and bleaching: blanch the shell buttons that have gone through the above procedures, and then put them into a rotating bucket to rotate and rub with water to polish and bleach them.
Such a beautiful shell button has been completed.
Because the shell is from nature, it sends out elegant and attractive breath from inside to outside.
