FAQ
General information only. Never leave a burning candle unattended, and keep it at least 12 inches from anything that can burn. When you heat wax, stay with it, and turn off the heat if you leave or see smoke. Never use water on a wax fire. If you can do so safely, slide a lid over the pot and turn off the heat; if the fire does not go out, get everyone out and call 911 from outside. Read and follow the Safety Data Sheet and instructions from the maker of every wax, wick, fragrance oil, and dye you use.
