Mypharmjar miron uv stash jars use special miron uv science glass that dramatically slows microbiological changes. The glass is proven in studies to keep any crop fresh and consumables fresher longer than any glass. The dark violet glass is infused with gold, UV glass blocks light while allowing amounts of violet, ultraviolet (UV-A) and infrared spectrums to penetrate.
