The fine essences were kept in jars made of gold and violet glass to preserve the value and effectiveness. The Swiss company MIRON-Violettglas AG combines this ancient knowledge with scientific understanding. This glass protects the contents from visible light. It also makes use of violet light as well as for UV-A and infrared.
They demonstrate the unique properties of their glass by using a clear glass bottle and a violet glass bottle then placing a cherry tomato in each. Seven months later, the clear glass tomato has flattened and is moldy, but the tomato in their glass bottle is red and eatable.
The young science of “Biophotonics” proves that light plays an important role in the life of organisms and organic materials. Scientists suggest that the light influences the exchange of information and energy in living cells in multiple ways.
