Two concerns - one of them being that I've got tons of CS fragrance oils along the lines of of sweet, home-y, spicy desert style scents. And so many of them are only slightly different from the other. I've been making container candles and testing religiously over the last almost 3 years, and still running into frustrating difficulties with h/t and c/t.
I've conducted endless testing using numerous natural wax blends, oils and CD, ECO, LX and other wicks of different sizes. My downfall is achieving decent c/t and even and consistent hot throw throughout the life of a candle. Using soy 464 wax, the best of all in terms of perfect adhesion to the glass when pouring at about 150, reasonably even tops, a long lasting burn, etc..still running right into the frustrating issues w/wicks .
A 3" diamater glass using a CD-22 wick is like a torch even at a reasonable 7.5%, while a CD-18 drowns immediately after lighting. I've been sticking with 185/150 mixing/pouring for the GB-464 blend, with two or more mins. stirring. So while CD-20 was a winner to start, after about 15 hours burntime, the CD-20 also began withering and the h/t was now non-existent.
I cure for one week before testing and then typically re-test at about the two week mark. I've also experimented with various wicks, fragrance loads and wax blends and the worst issue I've got is that c/t is almost always is faint over curing two weeks with lids, and the h/t throw may start out well, usually creating decent throw within an hour or so, then erratically deteroriating throughout all of the successive burn cycles.
I do not want any added toxic chemicals like Vybar to help boost my throw, so what else can be done here? At 7.5%, it's typically insuficient hot throw for numerous blends. At around 9%, it starts out strong then there is a dramatic diminishing of the flame height in the successive tests using CD-20, yet CD-22 produces the 2" high excessively wispy and flickery flame.
I am really exasperated after so many years of testing all the different components and failing to understand what is going wrong when not one wick will typically perform well consistently in all of the burntests-- rather, they excel at one point in the entire lifecycle of the candle - beginning, mid-candle, or nearer the end, and then either flare too high or start to drown. Any input would be appreciated!
