The sun emits visible and invisible light parts. The visible spectrum becomes visible to our eyes when white light is channeled through a glass prism. At the same time though, light also contains a part which is invisible to our eyes and lies in the radius of electromagnetic wavelengths of infra red and UV-A.

Sunlight enables all plants to grow. But, if natural products continue to be exposed to the sun after reaching maturity, the effect of the light changes and accelerates the molecular decaying process. Natural Healing Tools Violet Glass works like a natural filter that only lets the sunlight that protects and improves the quality of premium and sensitive substances.

There is a large spectrum of packaging materials available nowadays, of which many are permeable to visible light. The following graphics show to which degree light can penetrate the different materials:

Natural Healing Tools 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.

In order to substantiate these advantages, Natural Healing Tools Violet Glass AG has conducted a series of tests themselves and in cooperation with scientific institutions.
