Magical Frost Crystals
Both snow crystals and frost crystals grow from water vapor, but where snow crystals grow on suspended dust particles in the air, frost crystals grow on window panes, blades of grass, or just about any other solid surface.
When water vapor condenses into liquid water, you get raindrops or dew. When water vapor condenses directly into ice, then you get snowflakes or frost. Snowflakes are not frozen raindrops, and likewise frost is not frozen dew.
Window frost forms when a pane of glass is exposed to below-freezing temperatures on the outside and warm moist air on the inside. The water vapor condenses as frost on the cold window.
