Actually I do buy them (EC Wicks)from Candle Science. I buy my wax from Lone Star because I can drive there and pick it up and save myself the freight. I wonder does one company, I guess "Eco" make all of those wicks or is that a type of wick and not a brand. I know, probably a dumb question. I am just perplexed, but also, yes it is the Cinnamon Stick and the Antique Sandalwood from Candle Science that are suddenly not wanting to burn. And I have read on other threads that Cinnamons are one of the hardest scents to get to burn, but I used to never have any problems with either of these scents and I have been using both scents from the very beginning, when I started 2 years ago. And I am damn well not throwing out wax. I will just have to figure out something else.
