Distilled water is water without impurities and minerals that are usually found in groundwater. Distilled water is not suitable for drinking, but is recommended for household appliances, e.g. irons, to prevent calcification. To save costs, you can also produce distilled water yourself at home.

 

To make distilled water, you need a stainless steel pot with a stainless steel lid, water from the tap, a glass bowl and ice cubes.

 

Fill the stainless steel pot, which should hold at least ten litres of water, about halfway. Place the glass bowl in the pot so that it floats on the water and does not touch the bottom. The water that will accumulate in the glass bowl should not be brought to a boil. If there is enough water in the pot, the glass bowl will float on its own, if not, a steel grid should be placed underneath. the glass bowl should be large enough to catch as much of the dripping condensation as possible.

 

Turn the lid of the pot upside down and place it on the pot, fill with ice cubes. This step creates the heat-cold barrier that forms the condensation. Make sure the lid is tight on the pot and allows as little steam through as possible.

Bring the water in the pot on the cooker to the boil. The hot steam from the pot is held on the inside of the lid, where it becomes liquid again due to the cold surface and drips into the glass bowl. Occasionally lift the lid carefully and check that the condensation drips into the bowl as intended.

 

Remove the pot from the heat and carefully remove the lid. The distilled water has now collected in the glass bowl. The glass bowl will be hot, so only handle it with heat-resistant gloves! Before bottling the distilled water, it should cool down.

 

Substances dissolved in water, such as minerals and bacteria, are heavier than water molecules and accumulate at the bottom of the pot. Therefore, only the pure water evaporates and accumulates in the bowl. Caution: do not let the pot boil dry.
