The Science Behind Preserving Snowflakes
Snowflakes are among nature’s most intricate and short lived creations. Each one forms high in the atmosphere through a complex process of physics, chemistry, and environmental conditions. Due to being made of delicate ice crystals, snowflakes normally disappear within seconds of being touched or warmed.
Preserving one permanently requires carefully stabilizing of crystal structure before it melts or sublimates.
How Snowflakes Form
Snowflakes begin as tiny particles of dust or pollen suspended in clouds. When water vapor in the atmosphere freezes onto these particles, it forms a hexagonal ice crystal.
As the crystal falls through the atmosphere, temperature and humidity cause it to grow in branching patterns. Because these conditions constantly change during the snowflake’s descent, the crystal grows differently on each branch.
This is why no two snowflakes are exactly alike.
The six-sided symmetry seen in snowflakes comes from the molecular structure of water. Water molecules naturally arrange themselves into a hexagonal lattice when they freeze, which creates the characteristic six pointed structure of snow crystals.
Small differences in atmospheric conditions even fractions of a degree can cause dramatically different crystal shapes.
Why Preserving Snowflakes Is So Difficult
Snowflakes are extremely fragile. Their microscopic branches can break, melt, or sublimate (turn directly from ice into vapor) with even slight changes in temperature or humidity.
During the preservation process, snowflakes can be lost at several stages:
Collection
Snowflakes can melt instantly from body heat, warm surfaces, or sunlight.
Handling
The delicate branches can break when moved or transferred.
Stabilization
If the preservation medium does not cure correctly, the snowflake can partially dissolve or lose definition.
Encapsulation
If microscopic fractures form in the cured structure, liquid resin can seep inside and make the crystal pattern disappear.
Because of these challenges, only a small percentage of collected snowflakes successfully make it through the full preservation process.
The Role of Cyanoacrylate
The preservation process commonly uses a material called cyanoacrylate, a fast-curing adhesive related to the chemistry used in superglue.
Cyanoacrylate reacts with trace moisture in the air and rapidly polymerizes, forming a solid acrylic-like structure.
When applied under cold conditions, the liquid adhesive flows around the ice crystal and hardens. As the ice later melts or sublimates, the hardened material retains the exact structure of the original snowflake.
This process effectively creates a microscopic cast of the snowflake, preserving the natural geometry of the crystal in a stable form.
Once fully cured, the preserved structure can then be sealed within resin or incorporated into artwork or jewelry.
Why Bubbles Sometimes Form
Small bubbles may appear during the preservation process. These can form as part of the chemical reaction when cyanoacrylate polymerizes.
Factors that influence bubble formation include:
❅ humidity in the air
❅ temperature changes
❅ moisture within the snowflake itself
❅ how quickly the adhesive cures
These bubbles are a natural part of the chemical reaction and preservation process and are not uncommon when working with delicate ice crystals.
The History of Snowflake Preservation
The scientific fascination with snowflakes dates back centuries, but the most famous early snowflake researcher was Wilson Bentley.
Bentley, often called “Snowflake Bentley,” was a farmer and scientist from Vermont who became the first person to successfully photograph individual snowflakes in the late 1800s.
Over his lifetime he photographed more than 5,000 snow crystals, revealing the incredible variety and symmetry found in natural snowflakes. His work helped prove scientifically that no two snowflakes are exactly alike.
Modern snowflake preservation techniques were developed later by scientists and researchers studying ice crystal structures. These methods use fast curing polymers to stabilize the shape of snow crystals before they melt.
Today, preserved snowflakes exist at the intersection of science, natural history, and art.
A Rare Moment in Nature
Every preserved snowflake begins as a fleeting moment during a winter storm.
Capturing and stabilizing these delicate crystals requires patience, precise environmental conditions, and a fair amount of luck.
Each preserved snowflake represents a single crystal that once fell from the sky a structure that normally would have existed for only seconds before disappearing.
Preserving them allows that tiny moment in nature to last forever.

Artist’s Note
At Aurora Creations, each preserved snowflake is carefully collected during Manitoba winters and stabilized using a meticulous cold weather process.
Because of the delicate nature of snow crystals, every preserved snowflake is unique a small piece of winter captured forever.
