The tapped lacquer comes in liquid form, but once hardened remains solid and durable for the rest of its life. When we use Urushi lacquer, we begin with a thin layer added to the piece we are decorating for you, which we then let dry and oxidize in special heat and humidity conditions. This process is designed to harden the lacquer and, once dry, we repeat the process many times. During each layer applied, the lacquer absorbs moisture which gives it a unique, polished finish. Urushi lacquer is very durable and able to withstand erosion from water, salt, acids, alkalis, and changes in temperature.
