пожолтување

пожолтување

Describes a transformation inherent to all vegetable fibers which is caused by aging. Paper made of vegetable fibers will turn various degrees of yellow as its environment couples with aging to produce this phenomenon. Yellowing is very evident in groundwood papers and only a few hours in direct sunlight is enough to yellow newspaper.
