The image* above illustrates rather marvellously just why we choose to use Miron violet glass (left of pic) to house our products ~ it's the most advanced protective glass presently available, and is unsurpassed in preserving the life of products.
Violet glass isn't only highly protecting though; it also enhances the quality of the contents inside! It's been mentioned that our oils, with their stunning (natural) colours, would look rather lovely in clear bottles, and while I agree, clear glass offers zero protection!
It's not a new 'invention'; the protective qualities of violet glass can be traced back to ancient Egyptian times, when valuable essences and healing natural products were kept in gold and violet glass containers.
So how does it work? Well, clear glass allows light in the visible spectrum to penetrate through, causing products to degrade more quickly and encouraging microbial growth. Violet glass however, works as a natural filter, blocking the complete spectral range of visible (damaging) light except (beneficial) violet light.
Violet glass allows in 3 very specific frequencies of light that have been found to nurture and protect all natural substances: the visible violet light and non-visible ultraviolet and infra-red lights. The combination of these 3 frequencies of light actually improves the quality of substances in the bottle, thus lengthening the durability and potency of products.
And what about amber glass? Well, amber glass blocks the valuable UV rays but lets in most of the damaging light in the visible spectrum (whereas violet glass blocks all damaging visible light and lets in bacteria-killing, valuable UV).
Apart from the fantastic protecting AND enhancing properties it provides; I actually think violet glass is aesthetically rather stunning!
*image shows results of a real experiment where chives were stored for 60 days in violet, amber and clear glass, both in and out of sunlight. The difference is clearly visible between the preservation quality of each type of glass!
