Hey guys, I'm new to this side of the board. Just started making containers with EcoSoya Container Blend Advanced Soy Wax. So far I've had amazing results with scent throw and wicking with HTP...my question is this...how do I lengthen (sp) burn time....can I use additives in this was like UA, vybar or stearic? Looking forward to the responses! Thanks so much in advance for your help! Winsome
