Lacquer tree sap is a natural resin harvested from the Rhus verniciflua tree, primarily found in East Asia, used as a crucial ingredient in traditional lacquerware. This sap is processed to create a durable and glossy finish that not only enhances the aesthetic appeal of objects but also protects them from moisture and wear. The application of lacquer tree sap is integral to the creation of intricate designs and patterns in metalwork and lacquerware, particularly during the Goryeo period.
