I am sort of new to candle making, so please bear with me. I have been using Golden Brands 464 wax since I started making candles. At first, the tops were great! No cracks, just small little pits near the wicks. Not a big deal to me. But that was only the first few batches when I was testing. Now, in all the batches I'm making, the majority of the candles will have huge cracks and the parts that are not cracked are cottage cheese looking. But the kicker is that some of them turn out perfect!
My FO load is 10%, the max recommended for this wax.
Dye does not matter because it happens to both undyed and dyed candles.
I place the candles in the oven to make sure they do not get cooled too fast as my AC vent in the kitchen would blow right on them on the table.
There are no bubbles in the wax when I pour it.
The only consistency I see is in jar size. I have 3 different size jars I pour into when making a batch. The smallest ones will more than likely come out perfect, the mediums more likely come out bad, and the larges always come out bad.
I've been pouring around 130 to 140. However, when I was first making candles, I didn't pay attention to the pour temp. I added fragrance oil between 150 and 180, stirred, and poured right away. Now I heat to around 150, add fragrance oil and stir. I was getting a better hot throw by adding the fragrance oil at a cooler temperature.
Any tips to what could be causing these huge cracks? Also, any tips to perhaps fix the candles I've already made? I don't want to waste all that wax and fragrance oil. I know soy is prone to shrinkage and will produce SMALL pits and cracks, but it should not create cracks that you can see half way down the candle!
Thanks in advance!
