There are many methods of creating distilled water. One of the most basic (and inconvenient) methods of creating distilled water at home is by boiling water underneath a glass bowl. This might sound complicated, but it is actually quite simple if you follow a few basic steps. The first thing you need to do is get your supplies. This will involve a stainless steel pot that is big enough to hold around ten gallons of water. Also, make sure the pot comes with a lid because this will be a vital part of the distillation process. Besides the pot, you will also need a glass bowl that can fit inside the pot. Try not to use a glass bowl that is too small, but big enough to fit inside the pot without touching the sides. Finally, have a bag of ice on hand because it will help with the condensation effect near the end.
After you have gotten the supplies, you are ready to start distilling the water. First, take your cooking pot and fill it up with five gallons of water. You can use the water from your faucet since it is going to be distilled anyways. The five gallons of water should fill the cooking pot at least half way. If it comes up more than half way then you can empty some of the water out until half the pot is filled. If the five gallons doesn’t fill the pot half way then simply add more water. Next, place the pot of water on your stove and turn the burner on. Place your glass bowl on top of the water and let it float. If the bowl touches the bottom of the pot then you don’t have enough water. In this case, you would fill up the pot some more until the bowl floats without touching the bottom. Either that or you can use a circular baking rack and place it on the bottom of the pot in order to hold the bowl up from the bottom.
Now you just sit back and watch the water begin to build up in the glass bowl. You don’t want the water to be boiling yet, but rather just stay hot. Once water appears in the glass bowl, take the pot’s lid and flip it upside down. Place the lid on top of the glass bowl and then fill up the lid with ice. By this time, the water will be boiling and the condensation will cause distilled water to drip into the glass bowl. After you have enough distilled water in the bowl, carefully take the bowl out of the hot pot and place it down on the counter to cool off. Then just fill up some empty bottles with the water or any other method of storage that you prefer.
As you can see, while the concept is simple, the process is very inconvenient. Make yourself a favor, stop wasting your time, and get an automatic water distiller instead.
