Hello fellow tpfers, I am looking at buying some candles and can't decide between soy or bees wax. At the moment I have been buying a regular candle that uses paraffin alongside other ingredients. Apart from leaving a horrible black soot residue around the glass candle holder and above where it's burning. It has affected my asthma, caused headaches and catches the back of my throat. So.... what would you recommend Soy or Bees Wax?
