Herbal Vaporization Temperatures... Know Your Herbs and Vaporize Weed!
What Is The Vaporization Temperature Of... ?
Firstly, let's start by answering the question... What exactly is vaporization?
Vaporization is simply the conversion of liquid into its gaseous state... vapor. Vaporization happens at lower temperatures than the boiling point through the surface phenomenon known as evaporation, and as the temperature of the liquid increases, so does its vapor pressure. At the boiling point, vaporization happens at its utmost. The boiling point is the temperature at which the vapor pressure of the liquid equals the pressure of the atmosphere on the liquid. At the boiling point, most of the molecular bonds that hold the molecular structure together are broken and the particles move freely and apart as vapor. The stronger the molecular bonds of a particular liquid are, the more energy is needed to break them, thus the higher the boiling temperature of that particular liquid. The temperature of a liquid will not exceed its boiling point.
A liquid's normal boiling point is the temperature at which its vapour pressure is equal to the standard sea-level atmospheric pressure (760 mmHg = 760 mm [29.92 inches] of mercury). The normal boiling point of water is 100°C (212°F). At higher altitudes the temperature of the boiling point is lower, and at lower altitudes it is higher.
Now, back to answering... What Is The Vaporization Temperature Of... ?
To get an ideal vapor from your herbs, start at the low end of your herbs temperature range or below and increase as desired... herbs will vaporize at lower temperatures than shown here, but will do so more slowly.
Vaporizers differ in the way they heat, so they may run hotter or cooler at the bowl than at the heat source... and they also may fluctuate while being used as the heating element turns off and on in order to keep a generally constant temperature. The freshness and quality of your herbs will also, albeit to a lesser degree than the make of your vape, determine your ideal herbal vaporization temperature ranges, so experimentation is necessary... just use these numbers or lower as a quick starting guide and adjust as desired for flavor and strength or level of effect.
As you increase temperature, if you notice a yellow, grey or other smoke color in your vapor... that indicates combustion, so you might want to decrease the temperature. Although, some people like a little smoke in their weed vapor to add to the flavor or to ensure a greater concentration of constituents that have higher boiling points.
If you plan on experimenting, we recommend you choose a vaporizer with an adjustable temperature control... preferably one that shows and allows you to digitally set the exact desired temperature... such as the very highly regarded Volcano DIGIT.
The herbal vaporization temperatures listed below range from 212°F (100°C) to 392°F (200°C). Temperatures higher than 392°F (200°C) are generally not recommended because that is approximately when tars (particulates) and carcinogens such as benzene, carbon monoxide, hydrogen cyanide, napthalene, toluene, etc. start being significantly released.
Note: these temperatures are approximations only, for informative purposes only! Keep in mind that vaporization is a very efficient method of extract delivery into the body... so start with a minimal amount... and furthermore... ... in NO circumstance does an herb's inclusion on this list attest to its safety... in fact, some are poisonous!!! Assume that all plants have the potential to be very toxic; even common food plants, such as peanuts, have caused fatal allergic reactions in sensitive people. Do your own research, know your herbs, and vaporize weed!
