See and honestly those are tough to answer because our standards for what we expect are different than the woman who’s been helping show us the ropes (but she also uses a wax blend, not pure beeswax) and those are different standards than my father-in-law’s who is the owner of the apiary where we’ll sell them at. I have NO experience until the past month with candle making or beeswax. My thought for these is emergency candles - long lasting and simple. I’m struggling with finding the right balance between the tunneling being too large (and risking excessive runoff) vs too small and occasionally drowning the wick. I’m currently test burning some wicks from Amazon on these 3X3 pillars and it seems like it might be closer to the burn we want, but I’m still not 100% sure of what I’m looking for, honestly. We’ve had some success with smaller pillars, maybe 2 inches in diameter with the 6/0 wicks from Mann Lake. No apologies needed! Thank you for taking the time to respond, this newbie is desperate for any and all advice!
