The glass bottle method of distillation is similar to the glass bowl method, but it has a few more advantages. For one thing, when the process is over you will already have the distilled water in a bottle and won’t have to worry about transferring it from a large bowl to a bottle. Also, the glass bottle method uses some different tools as well. Besides the stove, cooking pot and tap water, you will need duct tape, two glass bottles, and an ice pack. One of the glass bottles should have a curved neck on top, while the other can have an ordinary straight neck. You need to fill the straight necked bottle up with ordinary tap water. Leave about five inches of space from the water to the top of the bottle. Next, you need to connect the two bottles together by their necks using duct tape. Make it so the openings of the necks are interconnected in a way to where no water or air can get in or out.
Now you will want to take a cooking pot and fill it up with five gallons of water. After that, place it on the stove and turn on the burner. Let the water sit until it is boiling in the pot and then place the bottle with water inside the boiling water. The other connected bottle will be hanging off the side of the pot, which is okay. You will want to try to tilt the bottle of water at a 30 degree angle because this will help it evaporate better. You should have your hand on the other bottle to adjust the angle. Don’t let go of that bottle because the duct tape is likely going to break. Finally, take an ice pack and hold it to the empty bottle that you have already been holding. This will create a hot and cold effect that will allow the hot water to evaporate and condense into the cooler empty bottle. Continue this until you have enough distilled water inside the bottle you are holding.
The glass bottle method is not traditionally used, but some people find it more convenient using bottles rather than a glass bowl with the lid of a pot. Either method will work find because they both evaporate and condense the water, which is the basic idea behind distillation. But again, either method requires trigger work, with a lot of inconveniences. You’d be better off getting an automatic counter-top water distiller, which besides distillation, it also has a charcoal filter to help clear close to 100% of remaining pollutants.
