I'm going to suggest something different. I would suggest that your first test candle should be an unscented, uncolored candle in the glassware (if you're using a container) that you plan to use. Then you can work to get the proper wicking. Once you have that down, that is your base candle with which you start from everytime. Order a new batch of was? Do a test candle to make sure it performs the same as your base. If not, you need to make adjustments. Once you have a base candle that is burning perfectly, then add some dye, but still no fragrance oil. Ensure that the wicking is still ok. If not, make an adjustment and record that. Then add fragrance oil and test again, the oil may cause you to change wicks again. All of this information needs to be recorded, if you get a batch where the base candle needs a larger wick then you know that your final products will probably need a larger wick as well. Hopefully, the manufacturer has enough control on their process that that won't happen, but can never be too safe. Better to find out from one test candle that a batch of wax is no good, than to pour 100 candles and then find out.
