Here are the candles after the 4th burn, they burned for almost 5 hours. For the largest jar I'll use the CD12. CSN9 ended up quite well in the small jar, I have not many so I think I'll use a CD10 for this. CD 10 in the largest jar lets too much shell. They are very long lasting, the throw is good wirh every wick to say the truth. Sharon, the swirls are really simple, I put 1 or 2 drop of color in the pot without stirring just before pouring, and voilà! Try it, it is fun! The wax seems similar to the one Richard uses. I have no problem with this wax, I like it more than soy, it's more consistent and tops are always beautiful!
