Viscosity is defined as the physical state of being thick, sticky, and semifluid in consistency. This is usually determined by the time it takes a given amount of any liquid to flow through, much like sucking a drink through a straw. When it comes to the topic of vaping, viscosity becomes a very important factor in an individual's vaping experience being pleasurable.
When heated, molecules in liquids become excited while gaining movement. This causes it to be more fluid, unlike when a liquid is cold and becomes difficult to move due to a high viscosity. Vaping warms up the whole tank, making the viscosity rapidly drop during a vape session. Starting at room temperature, after 2-3 minutes of vaping, the liquid is warmed. Meaning you start with light vape when drawing and end with a heavy, wet vape that may even result in flooding or gurgle that can ruin coils and waste e-liquid.
In a vape tank there’s a heating coil that is fed the e-liquid through either a fiber wick or tiny holes. An atomizer coil is the part of a vape that has the job of actually heating the juice. While temperature matters, flow rate is also determined by a vaper’s draw, which can lower pressure and allow more liquid to flow into the wicks. The acidity levels, as well as other ingredients, both play an important role in the lifespan of a coil. An old coil that needs to be replaced will eventually lose its heating abilities, effecting the viscosity as well. Classic signs of a coil needing to be replaced include things like reduced vapor production, leaking, gurgling, and poor flavor.
The amount of viscosity can be determined by the list of ingredients used to create the batch should be given attention if an individual is in search of something different. E-liquid can contain one or both of the following ingredients: Propylene Glycol and Vegetable Glycerin. While PG has no odor or color and can carry flavor more effectively, VG is a natural chemical that hits a lot smoother. Many that regularly vape have reported throat irritation from the PG that is included in their juice. Additional side effects also include dry mouth and an increase in thirst that can last anywhere from a few days to a week. It is also important to know that the risk of negative side effects and allergic reactions are much lower with e-liquids that contain VG but the increased thickness can clog coils more rapidly. These are all crucial characteristics to keep in mind while trying to increase or decrease the viscosity.
While there are choices, there has been no evidence to support which ingredient is truly better, so the decision of which one is best depends on personal preference. It is suggested to find your vaping preferences through experience and change things, such as the type of coil or brand of e-juice, according to what you desire.
Vaping may seem like a confusing habit for those in the early stages of it, but the nicotine it contains is relatively safe in small quantities compared to cigarettes. It is also a less expensive option in the long run between the two. Just like anything else that is new or out of a comfort zone, DIY vaping can be learned.
