About
The character 箔 combines the semantic bamboo radical 竹 at the top, indicating its original material, with the phonetic component 泊, which also means to moor a boat. Initially, it referred to a screen, curtain, or shallow tray woven from bamboo, often used in silkworm cultivation or as a partition. Over time, the meaning broadened to include thin sheets of hammered metal, such as gold leaf or aluminum foil, extending the concept of thinness from bamboo to metal.
