Description
A macro image of some frost on a window. I love the design and colors of this image and how winter creates magical things we normally don't see.
Frost is the solid deposition of water vapor from humid air. It is formed when the temperature of a solid surface is below the freezing point of water and also below the frost point.[1] The size of frost crystals varies depending on the time they have been building up and the amount of water vapour available. Frost crystals are translucent, but scatter light in many directions, so that a coating of frost appears white. There are many types of frost, such as radiation and window frost. Frost may damage crops or reduce future crop yields, hence farmers may take measures to prevent it forming.
Window frost (also called fern frost or ice flowers) forms when a glass pane is exposed to very cold air on the outside and moderately moist air on the inside. If the pane is not a good insulator (such as a single pane window), water vapour condenses on the glass forming patterns. With very low temperatures outside, frost can appear on the bottom of the window even with double pane energy efficient windows. (Due to air convection between two panes of glass, the bottom part of the glazing unit is always colder than the top part.) The glass surface influences the shape of crystals, so imperfections, scratches, or dust can modify the way ice nucleates. If the indoor air is very humid, rather than moderately so, water will first condense in small droplets and then freeze into clear ice.
