Diy handmade iron cans crystal scented candles fragrance home decoration. Candles should be stored in a cool, dark and dry place. Excessive temperature or direct sunlight will cause the surface of the candle to melt, which in turn affects the degree of dispersion of the candle, resulting in insufficient aroma when ignited. When lighting a candle, first trim the wick of the candle by 5 - 8 mm; when burning the candle for the first time, please continue burning for 2-3 hours; the candle has a 'burning memory'. If the wax around the wick is not evenly heated and the surface is completely melted, the burning of the candle will be limited to around the wick. Always pay attention to keep the length of the wick at 5-8 mm. Trimming the wick can help the candle burn evenly, and can also prevent black smoke from burning and smoke on the candle cup; ensure that the candle is not in a ventilated place when burning. Wind can cause candles to burn unevenly. Even reduce the life of the candle; try to burn the candle after 2 hours each time, but not more than 4 hours: If you want to burn for a long time, extinguish the candle every 4 hours, trim the wick length to 5 mm, and light it again. Always remember not to blow out the candle with your mouth! This will not only damage the candle, but also produce black smoke, turning the wonderful aroma of the scented candle into smoke; you can use a candle-extinguishing cover to extinguish the candle, or use a candle-extinguishing hook tool to immerse the wick in the wax; when the candle is less than 2 cm Please stop burning.
