At 22 Stone Bloom candle vessels are composed of simple, natural concrete. Each being unique with no two being the same. Each one is handcrafted, hand poured, colored & sealed. Once the concrete vessel has cured I seal the inside with a water based, non toxic, natural sealant. After the vessel is sealed I hand pour virgin coconut soy wax along with phthalate free, non toxic premium fragrance oils. This coconut soy candle comes with a crackling wooden wick that is FSC certified, which ensures that products come from responsibly managed forests that provide environmental, social and economic benefits. Our modern candles are extremely clean burning as well as reusable.
