Pores in Coils
These are coils that determine a vapor output, taste of vaping and usefull life of batteries.
Last time we gained deep insight into the matter of wicking material choice for your atomizer. Today let’s talk about another highly significant part of your build — about your coils. You may already know that these are coils that are vaporizing your e-liquids. They are responsible for that stage when your favorite juice becomes vapor. Thus, these are coils that determine a vapor output, taste of vaping and usefull life of batteries. All these are surely affected by other variables of your setup as well, but coils are considered to be one of the most important tool to adjust all performance coefficients. Mechanical mods, for example, are so to say "adjusted" exclusively through the coil characteristics.

Let’s try to talk in plain English without getting involved in the maze of the laws of physics to insure so a comfortable and native understanding of the topic. Unfortunately, a slight insight into the school course of physics is required, but I’m just obliged to make allowances to all the humanities-minded people and vocational students. I’m not going to describe the types of coils here. There are lots of copyrighted materials, which would help vapers chose the right type of coils. Today our task is to study key features of coils and get a the questions answered, like "why does FRAMED STAPLE render flavor better than micro coils from kanthal 0.8 mm?".
At first let's define the basic coefficients of your coils performance:
1
Vapor generation means how much amount of vapor
will be generated by your coils in one pull.
2
Flavor rendering means how rich will be the flavor of your
e-liquid rendered by your coils.
Both coefficients go hand-in-hand and depend, first of all, on the evaporation area. Of course, both of them can be much influenced by construction and peculiarities of your atomizer, but let's try to put this variable aside. Let us suppose that we use a drip, which is quite poor in flavor rendering and in addition you won't succeed in trying to produce huge clouds with it when medium powered. Let it be good old Velocity with half closed side airflow. And I don't like this drip, I just consider it is quite a good example.
Let us suppose that we have equipped our drip with a classical build 2015 - 6 wraps 0.5mm kanthal.
We know how to wrap wire, to warm up and to center coils.
Let it be so. As a result we have a pretty good 70−80 watt coil depending on actual power of your device. It renders flavor and generates rather big clouds. But in fact all the coefficients of performance are not high.

At a certain point we feel that we need to change something and here we have a choice, which will help us level up our understanding of how coils work.

If we decide to enhance an evaporation area through adding some more wraps, we increase significantly both weight and resistance of our coils. This will produce a negative impact on performance coefficients of that same 70−80 watt coil. Coils will take a very long time to heat up because of their heavy weight and consequently they will generate less clouds. In addition, e-liquid will evaporate unevenly, and this may result in significantly changed taste and spitback. The solution could be increasing of our device power up to 80−90 watts. But in that case we will be drawn back to the initial coefficient of performance with perhaps a slightly better flavor rendering, but much shorter battery life: batteries will die faster and, besides, the vapor temperature will rise once again and that’s not good at all. It’s a common belief that too hot vapor destroys tooth enamel.

And here is the solution — that very method, which can be considered the ancestor of all the complex and exotic coils — that's clapton. For those living under a rock: clapton means that the thicker gauge wire is wrapped around with thinner gauge wire. We end up with something very similar to a guitar string.

Why is it better? It’s quite simple — it’s like enhancing of evaporation area without doing it in fact. (What?) In other words, our coils became porous, and those pores absorb e-liquid very actively and quickly. At that moment you can perform an experiment. Drop some drips of e-liquid to a simplest coil and some drips to a clapton coil. In the first instance your coil will absorb practically nothing and the e-liquid will instantly run through it. In the second instance the coil will absorb the e-liquid. So it follows that clapton coils can absorb the e-liquid and thus the vaping involves not only the e-liquid fed to the coils through a wick, but also the one accumulated by the coil.

We will end up with slight increase in the e-liquid consumption, weight, and resistance balanced against better flavor rendering and vapor generation.


Many vaping risk takers and pioneers had been guided by this principle. Understanding of all these peculiarities has once inspired creation of lots of interesting and very efficient builds. This topic will perhaps clip with someone of you, beginner vapers and you’ll wish to become engaged in it and then to create your own exotic and breathtaking build.
