The Science Section of the May 5, 2020 issue of The New York Times contains an article by by Oliver Whang on tengujo, the thinnest paper currently manufactured (“
For a Very Weighty Job, You Use the Thinnest Paper“). Whang describes how the paper is made, noting that because of its extreme thinness tengujo is of little use for anything other than paper conservation, and details how Soyeon Choi, paper conservator at the Yale Center for British Art uses thin strips of it to repair an 18
th century letter. An entire article devoted to one of their materials. Conservators interested in public outreach should be pleased .
