Can I add crystals or anything else to the carafes?

Although the use of crystals for the specific purpose of water vitalization is a different process than that used in TC glassware, all crystals emanate different energies and have different energetic properties. The energetic properties of crystals can be used to augment your experience of the TC glassware in any way you desire. Although not necessary for the vitalizing effect, crystals and other substances do affect energy and matter. We recommend a knowledgeable approach based on research and your own experience.
