A bong is a standard smoking device that uses water to cool the smoke for better smoothness and prevent coughing. The use of glycerin coils has become an additional feature as an alternative to ice packs. The coils are made in a separate chamber to maintain higher accuracy, but they are melted by hot air, before they enter the tubing base. This option is added to the glass piece and it helps the user experience smoother and more comfortable smoking sessions. The reason glycerin coils are beneficial to this type of water pipe is their ability to cool the smoke.

Thanks to glycerin, a common ingredient in many products, it serves as an excellent anti-freeze for smoke. Although glycerin does not increase the potency of cannabis, it improves the user's smoking experience. Glycerin prevents the formation of ice crystals when the water inside the pipe freeze by producing a rippled effect. Ice is also made inside the bong when infusions from fruits/juices freeze with solid substances like sugar or alcohol. By using glycerin as a substance that inhibits ice formation, bong users can create their own smoke clouds.

Glycerin coils are a modern water pipe technology, which allows you to have a much smoother inhale. The user can take the coil apart and pull it out of the water chamber to fit it into your freezer overnight or until frosty. A glycerin coil is an innovative method as well that prevents any wastage of water, therefore giving it a detachable property. With glycerin coils, you can use ice cubes to achieve the same results. However, in this case, you have no option but to get it re-frozen over and over again until your session gets over.

Pipe enthusiasts have tried using different methods and techniques when it comes to smoking. However, over time the preferred method by many is using glass pipes. When you are thinking of getting one, remember that not all of them are great or cool for you in terms of efficiency and strength. Clean and pure water is required for making these pipes last for a long time. The level of cleanliness will depend on how much strength you want to derive from the pipe. The stronger the smoke, the cleaner will be your glass pipes if you are using glycerin coils.
