I am the first to admit that I am a bit of a newbie. I have been doing quite a bit of experimenting with soy wax in recycled glass containers, most of which are in the 3.5" in diameter range. I have had several that upon the first burn, the small wax pool puts the wick out within a very short time of lighting the candle. But then others using that same wick (ECO10) burn just perfectly. I cannot seem to find any rhyme or reason as to why this is happening. Is it something really simple that I am doing wrong or do you recommend just to keep experimenting until I find the perfect combination. Thank you!
