& mdash; & nbsp; These patterns are really formed from freezing. Specifically, due to the temperature difference inside the room and & nbsp; outside, & nbsp; & mdash; explained polar explorer Valery Lukin, who led the Russian expedition to Antarctica for many years . & mdash; & nbsp; The moisture that condenses on the & nbsp; glass freezes unevenly: & laquo; pattern & raquo; depends on glass thickness and cleanliness, minor flaws, scratches and cleanliness etc. Ice crystals form along the stripe, forming a band, and then 'stems' separate from it. The process begins at the bottom of the glass, where more moisture collects, hence the 'woody'. the design is larger there, and & nbsp; at the top it is & nbsp; smaller. The conditions in the & nbsp; piece and & nbsp; on & nbsp; street are variable: temperature, humidity, pressure, change in wind speed. Therefore, & nbsp; & quot; vegetable & quot; the reasons are always different.
At the same time, many probably noticed that on high-quality plastic windows frosted patterns almost do not form. This is due to the & nbsp; fact that they have good thermal insulation properties so they do not breathe & quot; therefore, & nbsp; condensation with & nbsp; crystallization on & nbsp; ; them proceeds worse.
