Its shape and symbolic powers are transferred and will resonate in fluids. quality mattersthe water you drink and use comes to you through an involved process such as pressurization filtering sedentary storage etc. a process which has an effect on the quality of water as it comes out of the tap or bottle. Water's journey through pipes filters tanks and other processes we use to insure the essential safety of the water supply also takes out the natural vitality of the water as it is found in nature.nature's design glassware re-activates processed water and brings it «back to life» back to the energetic form it is in when it originally comes from nature. the spring: the best water for human health is fresh spring water. the stress: even the best spring water looses vitality and energy when it is moved through pipes and other forms of water processing. the remedy: nature's design glassware revitalises weakened processed water from any source. Other liquids such as juices and wine are also improved in taste and biological vitality when held in glassware. Normal tap water is weakened by the unnaturally high pipe pressure and the flow in said pipes. A 3 minutes stay in the carafe is enough to improve weakened tap water. The survey results come from the laboratory ef brown ch-3628 uttigen switzerland. productiontraditional craftsmanship is necessary for the production of products. Each carafe is mouth-blown using an individual pre-formed mold. This individual production process makes every carafe a unique work of art.the flower-of-life symbols on the bottom are emblazoned into the glass base at 600 degrees celsius (approx. 1100 f). made from heat-resistant borocilicate glass free of lead or any other heavy metals. cleaningthe flower of life in the base of the carafe (outside) is burnt in at a temperature of around 600°c and then coated with a food-safe protective coating. In principle the carafes are dishwasher safe. After 500 to 1000 washes in the machine and depending on the hardness of the water and the detergent the symbol may begin to fade. cloudy carafes - cause and solutionfrothy and cloudy carafes indicate that the carafes are calcified.the main causes of cloudy glasses are:- wooden items in the same wash cycle as glass- hard water- incorrect dosage of rinse aid or too little salt limescale build-up is best removed with warm water and a tablespoon of citric acid or vinegar*.
