The medicine made from ferric ammonium citrate + red blood salt is sensitive to light, so when it is placed under the sun or ultraviolet light, it will produce a chemical reaction, which will gradually change from grass green to gray blue, and will change to royal blue after washing. ※ Many construction drawings (blueprints) used in traditional buildings are also produced using this method. Q Blue Sun Story In the 19th century, British astronomer John Herchel invented the technique of cyanography (blue exposure) in order to "copy his own notes". But it was not widely known at that time. Until 10 years later, a female photographer published a series of books using the blue sun method in order to record plant species. It was also the first female photographer in the world! . https://c1.staticflickr.com/5/4541/38516954956_fd4ae03c20_b.jpg
