The agent made of ferric ammonium citrate + red blood salt will be sensitive, So on the sun or under the ultraviolet light, It will produce a chemical reaction, gradually turning grayish blue from grass green. After washing it will change to navy blue! ※ The construction drawings (blueprints) used in many traditional buildings are also made using this method. Q Blue Sun Story In the 19th century, British astronomer John Herchel to "copy her notes" Invented a cyanolithography (blue sun) technology. But it was not widely known until 10 years later. There is a female photographer who records the plant species. A series of books was produced using the blue sun method, and it is also the world's first female photographer! ----------------- Q will fail? Difficult to get started? Because the blue sun is needed for the sun (UV energy is different) Therefore, it is necessary to rely on experience to judge whether the sun is good or not. But it is not difficult to get started!
