Tinkbug - That's actually more than recommended. Most candlemaking sites recommend a fragrance load of between 6-10%, meaning 7.8ml to 13ml for 130g of wax. Have you tried using a bit less fragrance? Too much can make the candle flicker and smoke, and can also mean that the fragrance sinks to the bottom of the container. Also check your wick size - if the wick is too big or too small for the container, it can have a big impact on the throw of the scent.
Jmeleem - have you tried using container maker?
It's designed to help the soy adhere to the side of containers and leave you with a nice smooth finish.
The fluffy finish could be caused by a number of things:
Hope that helps!
- The temperature of the wax. If you pour the wax too early (too hot) it causes the wax to set unevenly. I use a little kitchen thermometer and pour mine at about 60 degrees, which usually gives a good finish on top.
- Cooling too quickly. I've known people to put their candles in the fridge or in front of a fan to accelerate cooling, which can also cause uneven finishes. Keep them at room temperature and out of the sun.
- Ratios of ingredients. Sometimes too much fragrance or container maker can cause a funny finish. I also find that certain types of fragrance can affect the finish - I've got no idea why, I just avoid those ones in the future.
