The aroma and flickering flame of a burning candle can certainly make any home feel more pleasant and inviting. However, in recent years candles have been criticized for containing lead and petroleum additives and numerous other toxins, causing concern for those worried about toxins in the air or for individuals with allergies or asthma. The good news is that cleaner burning and greener candles are becoming more readily available. I found these 100% natural soy tumbler candles and non-toxic tea lights at Green Nest. Perfect for enjoying a candle and maintaining fresh air, they’re petroleum-free, pesticide-free and contain no paraffin. According to Green Nest, the soy wax used in their all natural, hand poured candles is tested in a laboratory to guarantee purity. As an added plus, Green Nest soy candles are not tested on animals and contain all lead-free wicks. And, the cute little glass tumblers can be reused when empty.
