A mixture of vinegar, salt and hydrogen peroxide is used to produce a layer of rust on the iron surface. The slower the rusting process, the nicer the rust surface develops. After several days the rust layer has reached its final quality and is brushed to remove loose rust particles. After cleaning the iron piece is boiled in a thick green tea soup for a while. The tannin from the green tea is stopping the rusting process and changes the brown rust color into a dark brownish black which is highly appreciated by iron art collectors. Additionally the case parts were treated by applying Ki-Urushi (Raw Lacquer) by high temperature over a coal fire, a technique called «Yakitsuke»
