I have had a chance to test a couple of them, with mixed results. Lavender (CS) colored with oil infused alkanet had great cold and hot throw, but subtle. I used a lot (approximately 1 and 1/2 oz per lb) of fragrance so on the next one I will use the same amount or perhaps a little more. The candle did not burn well at all though. Weak flame that did not stay lit, and the melt pool did not extend to the edges of the container. I love the scent but this would be better for a wax melt since as a candle it does not burn well. I might remelt them and use them this way. Since it is a scent made primarily for candles, I assume the failings are due to me introducing about 1/2 oz coconut infused alkanet. I will test the scent without color to confirm and report back.
The second candle was uncolored, but I am reporting on it because I used a scent that has no candle information from the manufacturer (or distributor?), neroli from CG. I had used this scent by itself and in blends for scenting soap. This is my first use of it in candles with great success! 1 1/2 oz per Lb of wax was actually too strong for me, it scented my medium bathroom remarkably fast and for me a little too strongly. The melt pool extended all the way to the edges of the narrower container shown, and the flame was very bright and stable. Great candle, next time I will use less neroli fragrance, perhaps an oz per lb wax.
I still have about 4 scent/colors combos to test, hoping some of them do better than the alkanet!
