I buy all of my products through Candle Science and use GB 464. I've been making candles for YEARS and have always used a 6% fragrance oil load. I recently switched from tins to glass jars, so currently I'm using a 12 ounce jar (holds 9 ounces of wax, uses a ECO 14 wick) and a 16 ounce apothecary jar (holds 14.5 ounces of wax, ECO 16 wick). One of my customers told me their candle didn't have very good hot throw, so my most recent batch of candles I bumped up to a 12% fragrance load and sold about 15 of them today.
I was looking through the reviews of new scents to add to my line, and someone mentioned they used too much fragrance oil and their candle turned into a tiki torch. This of course prompted me to start googling it, and I see a lot of posts about fragrance oil pooling at the top of the candle and the surface of the candle starting on fire. I could just vomit I am so terrified.
GB 464, according to the Candle Science website, does in fact have a max load of 12%. That being said, the majority of the scents recommend a load of 3-10% for candles. So which is it? Should I be recalling all of my candles now and telling customers not to burn them? Is 2% in 464 that big of a difference from 10%? Anyone here use 12% consistently in 464 and never have an issue?
All of this being said, 2 of my scents formed craters when I was curing - some of them even had cracks in the surface, it looked like I could push on it and my finger would go through the surface. I chalked this up to me pouring too hot and too fast, used a blow dryer on them and moved on.
Sorry for the long post, I am just so scared that I sold a bunch of candles to people that are going to start their houses on fire!!
Thank you!
