water that has had many of its impurities removed through distillation
Bottle for distilled water in the Real Farmacia in Madrid
Distilled water is water that has been purified by boiling it into vapor and condensing the vapor back into liquid in a separate container. Any impurities in the original water, such as non-volatile or mineral components, that do not boil below or near the boiling point of water remain in the original container. For example, water escaping as steam from a boiler of heating system or steam engine, leaves behind any dissolved materials, which leads to mineral deposits known as boiler scale.
