Thanks to everyone - I am new to the site and am learning so much. I have only been working with candles for six months, but sure have spent lot of money testing. I use GB 444 and have had great luck, finally, heating to 185, adding FO off heat at 185, and pouring at 100. My 8 oz mason jars with EO 10 wicks are great. However, I am now trying to add the 16 oz apothecary jars to make presents for friends, and am having trouble finding the right wick. One challenge is that it has a 3.1 inch opening at the top, but the diameter at the base is 4 inches. I'm testing with 10 oz NG French lavender - EO 14 way too big, 10 looks like it may also be too big. Does anyone have suggestions? Should I double wick with a smaller size? I will be so appreciative for any suggestions.
