Ukichiro Nakaya’s snow crystals

In 1933, Ukichiro Nakaya observed natural snow and created 3,000 photographic plates of snow crystals, classifying them into seven major and numerous minor types. In these observations, taking photographs of natural snow and sorting their appearance depending on meteorological conditions, Ukichiro Nakaya felt the need to make artificial snow from ice crystals grown in the laboratory.

Ukichiro Nakaya generated water vapor into a tube of double-layer hollow glass, which was then cooled. Contrary to its initial expectations, creating snow crystals was not an easy task – instead of forming into snowflakes, ice crystals grew like caterpillars on cotton rope he used for nucleation.

On 12th of March 1936, three years after the first attempt, Ukichiro Nakaya produced a snow Crystal on top of a strand of hair from rabbit fur in his laboratory apparatus. In December 1937, Ukichiro Nakaya took photos of many types of artificial snow crystals from his lab. These photos were influenced by the 1931 book snow crystals Wilson Bentley, whom he admires greatly.
