I am new to candle making and to this forum. I have snooped around and have learned a lot from everyone in this forum. After making a few candles I have realized that candles are a system made from a container, wick, wax and fragrance. I found it was easy to determine the proper wick when not adding fragrance, but once fragrance was added to the equation it made everything a lot more difficult. This is because I use the same wax, the same wick and the same container, and they are all consistent. However, I found that every fragrance has different properties. However, being a logical person I realize this is all science so there must be a pattern that can be found. After doing some research I have read that fragrance oils with low flash points and low specific gravities have a tendency to be wicked down and fragrance oils with high flash points and high specific gravities need to generally be wicked up. Knowing this I feel if I had enough data I could hopefully find a pattern or system that would hopefully help predict whether or not a certain fragrance oil will need to be wicked up, wicked down or if no changes will be needed. The problem is I need data and I was hoping this community could help me with that. Of course anything that I learn through this process I will share with everyone and they can do whatever they wish with it. I think every person who has been making candles for some time knows the wick size that works best in their container without adding fragrance oil. I was hoping people could share which fragrance oils have caused them to wick up and which one have caused them to wick down from the ideal wick size for the container. For the sake of consistency, if you would like to participate you can share your information in this format: Fragrance Oil Name/Company/Flash Point /Specific Gravity/Then state how much you wicked up or down or state that you didn't have to. Here is an example: Butt Naked/Natures Garden/225 F/0.999/Wick Down -1 You can generally find the specific gravity in the MSDS sheet that many fragrance distributors share on their site. Not all do, but many of them will. To find any sort of pattern I will need the flash point and specific gravity, so if you only have one number it won’t be of any use. If the specific gravity is listed as a range, just post the lower number of the range. I think if we can get enough data, we will see some sort of pattern. This will save us time from testing numerous wicks and most importantly I think it will save all of us MONEY!
