I am currently in a testing frenzy. I am testing EcoSoya Advanced and EcoSoya XCel. Comparing throw from two different fragrance suppliers. I made 6 60z candles of the following (3 from EcoSoya Advanced and 3 from EcoSoya XCel): Each candle has a different wick CD6, ECO4, and small wooden wicks. Rain Coffee Tropical Fruit Salsa Jasmine Cool Water Fresh Linen White Cherry Blossom Fresh Linen Pine Rose Petals Tomorrow I am repeating the same scents by making 3-6oz of Golden Wax 444 and 3-6oz of EcoSoya 135. 120 candles in all. Luckily I have family members/friends who are going to be taking detailed notes as part of my testing process. I am going to be taking a trip in March to LoneStar and AAA Candle Supply in Texas and want to make sure everything is exactly how I want it before purchasing rather large amounts.
