About UV Glass

All of the oils for our 1886 Essentials Collection line are stored in special Miron Ultra-Violet glass bottles. We chose these highly specialized ultra-violet bottles  as opposed to the traditional amber or clear because of it's amazing ability to not only protect but enhance the items stored inside.

Through rigorous testing, this glass has proven itself time and again. They say the proof is in the data and since honesty is our game. We've gone ahead and put together some great information for you. So you know what you're getting with this awesome glass.

Miron violet glass blocks the complete spectrum of visible light with the exception of the violet part.  At the same time it allows a certain part to be permeable for radiation in the spectral range of UV-A, and infra red light. This unique combination offers optimal protection against the ageing processes that are released by visible light, thus lengthening durability and potency of products.

Several tests have been done to prove the viability of this glass using various stored liquids and solids.  One of these tests was done using various herbs.

Sprayed-, white-, green- and amber glass are permeable in the visible light spectrum and don’t offer enough protection against decomposition caused by light. As an experiment, several herbs and spices were stored for 3 months in several types of glass (clear, amber, violet), and were either exposed to the sun for several hours a day or kept inside.

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 below, 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.
