Misconception: Since glass bottles are classier than plastic ones, the products in them must be of a higher quality.
In the packaging world, glass is often used to maintain product stability. Items that are in no danger of becoming unstable are most often packaged in polyethylene terephthalate (PET) plastic, a type of polyester. Many fruit juices, bottled water, and soft drinks are packaged in PET. In fact, the highest number of beverage bottles manufactured globally are PET.
True colloidal silver does not require any help from its packaging to remain stable. As a result, many products are stored and shipped in PET bottles.
Ionic silver solutions and other mixtures masquerading as colloidal silver are often unstable in the presence of visible light, which will cause the photosensitive products to deteriorate, sometimes rather quickly. Amber-colored glass are used to shield such photosensitive products from visible light, thereby increasing their shelf life. Thus, products stored and shipped in amber bottles tend to be of the lowest quality.
