Tea Hack: Using sencha tea for rust prevention (ancient Japanese method)

August 15, 2013

A Japanese article published on the website of the Japan Society for Analytical Chemistry outlines research into the effectiveness of sencha green tea in rust prevention. The historical background is translated below:

Nishi Honganji temple in Kyoto, built in 1636, was repaired in 1810, and again in 1998. At that time, the nails used in the roof tiles were considered to be culturally important and it was decided that they would continue to be used for posterity’s sake after strengthening rust prevention. The method used for rust prevention is the same traditional method used in Nanbu Tekki cast ironware and the guards of samurai swords, boiling in sencha tea.

1636年に建立された西本願寺御影堂(京都)は1810年に大修復され、次いで1998年から平成大修復が行なわれている。御影道の屋根瓦を止めていた瓦鉄釘を文化的な価値から後世に残すため、防錆化し再利用することとなった。その防錆化の手段として古来、南部鉄釜あるいは刀の鍔に利用されてきた煎茶での煮沸処理技術を本鉄釘にも採用した。
