etchant
Metal-biting chemical
An etchant is a chemical substance used to etch—to eat away or corrode a surface in a controlled manner.
In electronics manufacturing, etchants remove unwanted material from circuit boards.
In metalworking and printmaking, they create patterns or textures by selectively dissolving exposed areas: The copper was immersed in the etchant for several minutes.
