I make my own candles.
Tried the dip method. Also used molds (single and gang molds). Tried beeswax, paraffin wax and various combinations. Having candles around is downright handy.
Best combination I’ve found so far is a 50/50 mix of beeswax and paraffin wax, poured into a 6″x1″ mold. The 6×1 seems to balance weight and longevity pretty well. You have to age them, though. Believe it or not, if you age a poured candle about 6 months, it will last longer. Half a dozen of them weigh almost nothing, but be advised that mice LOVE to chew on beeswax candles, so package them accordingly.
