About UV Glass
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.
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.
