What temperature to select?

[Hooked]

I've just come across some interesting info which I've copied from:
https://www.vapingpost.com/2016/10/25/temperature-control-mode-how-to-use-it/

"...the optimum temperature is difficult to assess due to the variety of reactions and the different compounds that are met. Based on readings on various forums, users generally opt for a temperature value around 250°C for puffs shorter than 5 seconds. At a lower value, the coil does not heat homogeneously andThey evoke the “cooking” of their juice when gunk build up on the wick, which is generally associated to a degraded flavor. Sometimes, flavor degradation is extreme and leads to a repulsion that expert users associate to the production of acrolein, a molecule that it is preferable to avoid.

MY QUESTION: What do they mean by "temperature value around 250°C"? Is 250°C the '25' on my Twisp Mini Vega, which has variable wattage - obviously not up to 250 otherwise I'd be flying over the rooftops - or the ocean, in my case!

Now here's some interesting info:

Water boils at 100°C, Propylene Glycol (PG) is vaporized at 188°C (or 371°F), Vegetal Glycerin (VG) at 290°C (or 554°F) and ethanol at 78°C (or 173°F)."

"...depending on your device and the juice you vape, a minimum of heat is needed to produce vapor. In mixes, different liquids are present with different properties and boiling points."

"Other constituents are also present whose concentration and composition are also very variable from one juice to another. The most common is nicotine whose concentration cannot exceed 2% in Europe, but with values up to 4.8% in certain juices like those used in the Vype ePen, for example. Nicotine’s boiling point is reached at 247°C (or 477 °F)."

"Flavorings can reach up to 20% in volume of the final blend. Diacetyl, for example, that gives a buttery taste, boils at only 88°C (or 190°F), for acetoin giving the same flavor, it is higher (148°C or 298°F)."

"Flavours:
For the flavor of banana, isoamyl acetate is vaporized at 142°C (or 288°F).
Benzaldehyde (cherry taste) boils at 178°C (or 352°F)
Cinnamaldehyde (cinnamon taste) at 248°C (478°F).
Fruity flavors (ethyl propionate) boils at 99°C (or 210°F),
Grape (Methyl anthranilate) at 256°C (or 493°F),
Orange (limonene) at 176°C (or 349°F),
Pinnaple (allyl hexanoate) at 190°C (or 374°F),
Cotton candy (ethyl maltol) at 161°C (or 322°F)
Menthol at 212°C (or 414°F) and vanilla (vanilline) at 295°C (or 563°F)."

Crikey! With all those variables, would it ever be possible to vape at the appropriate temperature??

Nope, I assume 25 would be the watts on your twisp.

You need a TC (Temperature Control) mod to be able to set the temperature of your vape. VW only allows you to set the wattage.

I personally use temp control simply to avoid dry hits - cotton burns at around 280 degrees so I set my temperature to 275 degrees. Then I can use whatever wattage I want.

As the members above said, your 25 on your mod is 25Watts not temp control

In order to do temp control you need a temp control mod and a coil that supports temp control. Typically, a coil that supports temp control is made of something like stainless steel or NI200. These materials change their resistance as they heat up. (Normal non temp control coil materials dont do this). The mod uses the resistance change as an indicator of the implied temperature of the coil.

I havent experimented much with temp control. Have tried it a few times but it hasnt gripped me yet.

Your post was very interesting because of the other snippets you added. In particular the boiling points of the various flavours. With some juices, some of the flavours are enhanced at certain temperatures. It is for this reason. I find this quite fascinating. Thanks for the post

@Silver In future I'll check the boiling points of the flavour profile, then start my vape with a low wattage, hold the vapour in my mouth while I'm increasing the wattage, then exhale. Maybe that will give me the true flavours at their respective boiling points!

Thanks for the link @Raindance but I was getting temperature and wattage mixed up. I don't have a temp control device and nor am I likely too in the foreseeable future!

@Hooked, having followed your assimilation into the vape scene over the past couple of months, I dare to predict a TC mod in your future. LOL. After all, resistance is futile!
