Bright outdoor sun makes heavily frost encrusted glass pane an enchanting micro-world of fir tree-like patterns growing on black window screening.
A touch of photo-editing creates this very interesting image based on vestiges of our recent sustained, very cold, minus twenty Celsius, winter weather.
Frosting is the result of heated warm moist interior air contacting a very cool glass pane surface made that way by extreme outside winter weather temperatures.
This phenomenon normally happens on ancient type single pane windows like those old sliding units having two sets of panes, these are incapable handling the humidity generated inside a home during winter.
Modern triple glazed thermal windows on the other hand can handle humidity much better than the ancient windows of yesteryear, and are superior to double glazed windows they replace.
