Perpetual Wall Calendar, 19th century
Decorated in the Eclectic style of the 1800s, this wall perpetual calendar was made in France and is shown here in a version for the English market. It was made of Bois Durci, a composite plastic material based on Albumen, obtained from blood from slaughterhouses, mixed with a filler of wood flour and molded in steel molds under heat and pressure. This material was patented in France in 1855 and was used until early 20th century. It is 31cm high and misses the clock, the thermometer and the barometer.
If you want to know more about this material and design, please visit the site of Bois Durci specialist Harold Mernick, Bois Durci Information Center and see his fantastic collection. Then go to the site of another Bois Durci specialist, Gaston Vermosen, and buy his amazing book on the subject.
