Prussian Blue - Back to the lab again


A few days ago we synthesized a pigment called Paris Blue, also known as Prussian Blue. This week we were finally able to mix and test this new pigment.

Pigment, Paris Blue, Prussian Blue, Berlin Blue
The dried & ground Prussian Blue pigment.
This pigment was especially used by artists during the period between the 1700s and the 1900s. Some artists includes Vincent van Gogh (Starry Night), Delacroix (Pieta) and Katsushika Hokusai (The Great wave off Kanagawa).

Paint, Oil, Paris Blue

Our Paris blue turned out great. Initially I was a bit over enthusiastic and did not grind the blue pigment fine enough and suffered an initial shock of disappointment as the paint appeared more grey than that Starry Night blue (top row in the photograph above). We then regrouped with a finer grind of the dried pigment, which really brought out that colour (bottom row). Through this we learned a valuable lesson: you must properly grind your paint for more vibrant results.

We plan to use this pigment until we have refined our Egyptian blue.
