Oil flash points were obtained by simply pouring water into a pan, droping in 2 or 3 drops of essential oil, turning on a low heat, placing a thermometer into the water only (so it's not touching the pan) and waiting as the water (and oil) slowly heated up. The rate of heating used in these experiments was 1 degree rise in temperature roughly every 2 seconds. At some point, the oil would have a subtle steam like effect as it started to vaporize. The temperature at which that occurs is called it’s flash point.

Knowing an essential oil’s flash point can be useful for a few reasons.
 1. Flash points can serve as a guide for which oils might be more useful in a bath. If given the option of German Chamomile or Roman Chamomile, the German Chamomile might work a little better since it will take a little longer to vaporize away.
 2. Flash points are useful when making soap for a similar reason. Essential oils with low flash points may vaporize away during the soap making process and not actually make it into the soap...
 3. Flash points can also be useful to check to see if an essential oil is authentic and genuine. Minor variations from the temperatures listed below are likely to occur since oils are all unique products of nature, harvesting method, distillation method, etc. However, if oil from a bottle of Roman Chamomile oil is tested and it doesn't flash out of the pan until 178 degrees, that should be a red flag.
