These days, coils come in all shapes and sizes, but glycerin coils are one of the more interesting ones. So how do these things work? First, it's important to know that glycerin coils are only used in E-cigs, not in vapes or the new disposable e-cigs. They're used in E-cigs because e-cigarettes don't produce vapor, just smoke.

Glycerin coils are the heating coils used in electronic cigarettes and vaporizers to power the atomizer and produce vapor from e-liquid, e-juice, or e-liquid. The primary purpose of these coils is to heat the e-liquid, which, in turn, creates the vapor that smokers inhale and exhale through the mouthpiece.

What Are Glycerin Coils?

A glycerin coil is a wire coiled to form a wick or coil. This wire is coated with wax and impregnated with glycerin, which becomes liquid in the heated coil. The element's heat heats the liquid, producing a vapor that comes out through the mouthpiece at the end of the device.

The coil sits inside a small metal cage. This cage is called a tank, and it holds your e-liquid. The heat of your batteries heats your coil, which heats your e-liquid and turns it into vapor.

A glycerin coil is different from a regular wick, absorbing e-liquid from your tank and becoming saturated. When your wick is saturated, it won’t be able to absorb any more e-liquid.

A glycerin coil does not need to be saturated. A heated coil will keep producing vapor for as long as you keep it heated. As your coil heats up, it produces more and more vapor until, eventually, it cools down enough that you'll need to drip e-liquid onto it again.

How Do Glycerin Coils Work?

Glycerin coils are a lot like steam coils, except they use glycerin and water to heat the space instead of the more traditional way of using steam. These coils usually come with an electric resistance wire wrapped around them that provides the heat to create energy, which then warms glycerin in a closed system. With both liquids mixed, this creates an almost instantaneous heating source more efficiently than traditional hot water pipes used in other places such as houses or offices.

Glycerin coils are perfect for people who like thick clouds and vaping at higher temperatures. Depending on your chosen coil head, they come in 0.5, 1, and 1.5-ohm resistance levels with low to high voltage options. Glycerin Coils function differently than cotton coils because glycerin is a thicker liquid that takes more time to vaporize at higher temperatures than cotton wicks.

Types of Glycerin Coils

Glycerin coils can come in three types of coil configurations: Vertical (like those used in electronic cigarettes), horizontal, and wickless.

A vertical coil will most likely have an instruction manual on inserting the coil into the atomizer for use with a personal vaporizer or e-cigarette device. 

A horizontal coil will most likely be inserted into an atomizer with a built-in heating element.  

Wickless coils are typically made of Kanthal wire wrapped around cotton wool, so there is no need for additional wicking material. Wickless coils are also referred to as direct-wick, but they may still require some support, such as stainless-steel mesh.

How Does Glycerin Work as an Atomizer?

Glycerin works as an atomizer because it is a polar molecule with both positive and negative ends. The positive end attracts the nicotine and flavor molecules in the e-liquid, and then the glycerin’s negative end accepts these molecules from the solution. When enough of these molecules are on the glycerin's surface, they form a bubble. When this bubble bursts, the vaporization process begins, and the user inhales the aerosol containing nicotine vapor and flavors suspended in water vapor.

Advantages of Using Glycerin Coils

Glycerin coils provide excellent flavor and throat hit for the user because of the smaller contact area with air. The coil can also produce more vapor by having fewer contact points, making it a perfect choice for pod-style vapes. Furthermore, glycerin coils last longer than traditional organic cotton coils and can be used in high VG juices with no risk of leaking or spitting back. They are easy to use and maintain, requiring less maintenance than other styles of coils.

Disadvantages of Using Glycerin Coils

One of the disadvantages of using glycerin coils is that they are not a good choice for groups with varying levels of the smoking experience. This is because glycerin coils don't produce very high heat, so someone who isn't used to smoking may be unable to take a hit. This is because inhalation from traditional cigarettes or nicotine delivery systems provides higher temperature amounts than what you get from glycerin coils.

Final Thought

Glycerin coils are heated until all three substances vaporize, then get inhaled through the mouthpiece. When inhaling on a glycerin coil, it delivers more flavor than usual because there's more room for it to evaporate and produce more vapors. The downside is that glycerin coils don't last as long as traditional vape pen coils. The good news is that they are fairly easy to replace. Just unscrew the old coil from your tank, screw on a new one, and you're ready to go.
