In our most basic scientific terms, we define matter as existing in one of three states – solid, liquid and gas. A phase boundary exists between the different states of matter and is mostly defined by temperature with other factors such as pressure and composition of the matter. Many substances known to exist have the ability to be transformed from one state to the next by introducing a catalyst such as heat. A vaporizer utilizes these general properties of matter and uses heat to transform a substance, whether solid or liquid, into a state of gas known as a vapor.
With these facts in mind, it is likely evident that temperature control is critical in creating vapor. Certainly, all vapor is not created equal as there are a number of factors to consider when using a vaporizer to complete the process. As different substances vaporize at different temperatures, the correct combination of these components is crucial. Some factors to consider include the proper temperature for the matter being vaporized as well as the state of the matter being vaporized. Carefully arranging the correct combination of these factors provides the greatest control over the elements found in the resulting vapor.
For instance, in the case of an herbal vaporizer, the heat applied to one type of herb may provide drastically different results from the same heat applied to another type of herb. An herb such as eucalyptus vaporizes at a temperature of approximately 266 degrees Fahrenheit. Attempting to vaporize a substance such as cannabis at this temperature would have very negative results as the cannabis would not create a good vapor until the temperature reached a level of nearly 100 degrees higher than that of the eucalyptus. As a result, the cannabis vapor would be mostly comprised of air rather than plant vapor.
Just as important as the variety of matter being vaporized is the state of that matter. An oil extract of the same aforementioned herbs would require a different temperature in order to vaporize as the same herb placed in a vaporizer as a raw plant material. The matter used in a liquid state and placed in a vaporizer in this state transforms when a higher level of heat is added and the liquid is brought to its boiling point. By bringing the matter to the point of boiling, ingredients are activated beneath the surface of the material. The ingredients are released from the liquid as a concentrated flow of elements that becomes the vapor.
