"Japanning" refers to European efforts to create finishes that resemble East Asian and Indian lacquer and decoration. It was completely cultural appropriation for its day, but in their efforts to recreate a varnish they couldn't make, they created something new as well.
I've collected a list of books, and sometimes their contents, here for sharing. My focus is on japanning wood with shellac varnishes, but I'll include other meanings of japanning over time.
(Yes, right now this is English-language-centric. I hope to expand well beyond that!)
