I recently created candles in these mini mason jars using EcoSoya Advanced wax (no longer available) but heated to about 140, added FO and poured resulting in a beautiful appearing candle. The smallest wick I had was an Eco 2 so used it, which was too big so burned too hot. It provided phenomenal hot throw but liquified the entire candle very quickly. I tried making a few using a WI700 series wick (735) and a different FO which achieved a slightly slower burn but the hot throw was not good at all. Because they are so adorable, I will try them again using the wick Candle Science recommends. They are quite cute.
