2 months storage of chives
"After 2 months, the visible quality change was recorded with photographs, and the difference in smell determined in a blind test with volunteers. The illustration shows clearly that the chive samples that were exposed to the sun have bleached in brown and white glass. As photographed in this illustration, the sample stored in MIRON violet glass shows no color change. The smell of the chives stored in MIRON violet glass was also clearly stronger and fresher."
