My candles are made with Soy products including the wick. Essential oils are used to make the candles. I also use color specific to individual scent and container color is random. The Aromatherapy ones, I include one ingredient so you can research its usages and what it promotes. Not all aromatherapy oils have a floral smell. However, it's the therapeutic element that it provides. It is recommended that a candle should sit for at least 2 weeks or more to provide a more throw of smell. For the tins and glass ones, I recommend to follow candle burning instructions for all i.e. never leave them unattended, never around child/ren, pets etc. and always burn the tins and glass candles on a heat resistant item such as a thick glass candle dish holder. For the melts, a glass fragrant oil warmer that has the glass dish wax melt bowl, is perfect. It cleans well using a Brillow Pad/Steel Wool Pad (once you have poured the old out of course). The 2oz burns up to 14 hours. I don't recommend burning it straight like that however.
