There are many types of clothing buttons. Some simple buttons can be seen from the surface of the material, and some buttons are not easy to distinguish.

Button materials are roughly divided into plastics (resin, plastic), metal buttons (copper, iron, alloy), natural (shell, wood, coconut shell, bamboo. arious materials need to be made into buttons, the process is different. Some buttons look the same, and even people in the button industry may not be able to tell clearly. Only by destroying and scraping the outer clothing can they be distinguished.

Buttons are divided into Plastic Buttons and resin buttons, plastic (including various plastic) buttons are generally die-cast, so there will be a line on the side of the button, this mold line, some factories may This line is removed in subsequent processing, but it will be lighter than resin (of course, some special plastics will be heavier). Resin buttons are mechanically carved and then polished, so there is no full mold line on the surface, which is very smooth. However, it is fragile, the surface is easily scratched, and it will become soft in boiling water.

How to distinguish between copper buttons and iron buttons? Buttons made of copper or iron,you can find this with a magnet. You can also use a hard object to scrape the surface plating layer. The inside of the copper button surface is brass (gold). The iron buckle is black, which is the color of the raw material.

How to determine if it is an alloy button? The alloy buckle is made by die-casting. All the mold lines are generally polished and polished. It may not be visible, but it has a heavy weight.
