Why we use brown and violet glass
Amber glass is usually legally prescribed as a container for pharmaceutical products. But this is not the only reason why many products in our Saint Charles Apothecary own line are filled in amber or violet glass. There are many advantages to filling products in coloured glass. In this post, we want to look at the reasons why brown and purple glass is best for storing valuable ingredients.
Glass for storage and preservation
Glass is the perfect material to package food because it is inert. This means that the container glass does not react with its contents, does not give off any taste and does not take on any odours. The colouring of glass also serves an important purpose - it influences the quality of certain goods. When natural products are left exposed to the sun after they have matured, the effect of sunlight changes the product and molecular decay is accelerated. Brown and violet glass provide the best protection against light. The brown or purple glass absorbs most of the ultraviolet radiation, protecting the product from light exposure and helping to preserve the essence of natural products. The protection of the glass ensures that the taste, smell, colour, bio-energy and properties of the product are preserved for longer.
Abrown glass is created by colouring clear glass with sodium sulphate and iron oxide. Jar, pharmaceutical jars and bottles made of amber glass are less translucent than white glass and thus filter harmful UV radiation. Medical products, sensitive oils and capsules are therefore carefully filled by us in amber glass containers.
The special feature of violet glass
Dark violet glass offers extra-class protection. It is therefore particularly well suited for delicate liquids or other biological substances. Based on indications, the Miron company succeeded in 1991, after 7 years of research and many melting trials, in finding the optimal shade of violet glass. Violet glass allows invisible ultraviolet and visible violet as well as invisible infrared light to enter the glass, but not the other visible light frequencies (blue, green, yellow, red) of sunlight. They are rejected. Due to the approx. 25 % transmission of the short-wave UV radiation, the biological substances of the contents are stimulated. Thus, the unique properties of violet glass not only preserve products in a natural way but also improve their effectiveness.
The special properties of the glass create an additionally energetically charged environment. The substances contained in it are constantly revitalised and even strengthened by the only selectively penetrating light. All research came to the conclusion that in violet glass, highly sensitive substances by far receive the best preservation (of taste, smell, colour, structure and enzymes) and optimal bio-protection. Tests have shown that products stored in Miron Violetglass retain their characteristic properties over longer periods, sometimes even years.
In order to do justice to the valuable, natural ingredients and to preserve the effect for as long as possible, in addition to many products in amber glass, particularly delicate natural products such as essential oils or hydrolates are bottled in precious violet glass from Miron.
