Snow Crystal Classification

Snow Crystal Classification translates Ukichiro Nakaya's 1954 morphology charts into a design system. In his Hokkaido laboratory, Nakaya sorted dendrites, plates, and columns across a temperature-versus-humidity grid, photographing each crystal under dark-field illumination.

Reflected light yields frosted white-cyan figures on a deep cold field, with a documented blue cast for the icy reading. The result is a rigorous scientific taxonomy — six-fold hexagonal symmetry, labeled axes, one specimen per cell — distinct from Bentley's white-on-white plates.

「雪晶分类」将中谷宇吉郎 1954 年的雪晶形态图谱转化为一套设计系统。在北海道的低温实验室里，中谷沿着温度—湿度坐标网格，将枝状、片状与柱状雪晶逐一归类，并以暗场照明逐颗拍摄。

反射光在深冷底场上留下霜白偏青的晶体图像，并带有文献记载的冷蓝色调，使其更显冰冷。整体是一套严谨的科学分类法——六重六角对称、标注坐标轴、每格一颗标本——与本特利的「白底白晶」图版截然不同。这是科学的网格，而非节庆的装饰。
