BERLIN BLUE


In the year 1706, Johan Jacob Diesbach tries to make his usual koshinel red. The mixture needed ground Dactylopius coccus bugs (named E120 or carmine and used as food coloring), potash and Ferrum sulfate. He had no potash, so he asked his friend alchemist Johann Konrad Dippel for a small amount. Unfortunately, Dippel's potash had been mixed with blood or animal oil and gave the unplanned reaction in the mixture. Ferrum sulfate turned to Ferrum ferrocyanide and this made the color blue instead of red. The beautiful Berlin blue was created by accident.
 
When you boil this unpoisonous mixture, Ferrum(III) ferrocyanide turns to hydrogen cyanide. Nazi used it as a component for their Zyklon B poison to gas thousands of people in their concentration camps. Americans used cyanide gas in WW1, but the poisonous gas happened to be lighter than air and didn't stay long enough at the battlefield to be productive. It rose to the sky too quickly.

 

 

 
   

 

 

 

 

 

 

 

 

 

 

 

 

   

 

 

 

 

WHAT CAN BE KILLED BY A SAMURAI CLOTHES?


Sukumo – Persicaria tinctoria leaves dried and then fermented for one hundred days. It is used to dye fabrics indigo blue. The whole poetry is in the moment of taking the fabric out of warm dyeing liquid. The fabric is green and when it touches air it oxidates and turns to blue in seconds.
Clothes of samurai were dyed with indigo and it is said that they stay antibacterial, fire-resistant and even protects from snakes and insects.

 
   

 

 

 

 

LIGHT SOURCE


Pyrocystis lunula is marine algae. They emit a flash of blue light when the water is disturbed. The flash is meant to attract a predator to the creature disturbing or trying to consume the algae. They use sunlight as their main source of energy (photosynthesis).


I had an idea of showing them in a dark box, available for the viewer to disturb the water and witness the blue light flash. But then I thought, that sometimes it is not that bad to have something quite miraculous looking like an ordinary transparent water flask.
