Swift-Lite carbon discs are long-lasting mini carbon discs that ignite quickly and easily. Swift Lite is a premium brand - they ignite easily, burn evenly, stay lit, and won't spill or explode. It is recommended to remove one of the discs from the roll and hold it by hand or with metal tweezers, hold it close to the flame of a match or candle, letting it light. You will see that it ignites quickly and immediately sparking over its entire surface since they are self-igniting, carefully deposit the disk in an appropriate censer or burner for its use. Deposit the charcoal with the bowl facing up so that you can deposit the incense granules comfortably; the disc must be allowed to burn and cool in the censer. Ideally, allow the disc to fully ignite for a few minutes until it is completely covered by a layer of gray ash, then it will be the right time to place the granules or mixes on the disc. When the charcoal is done, sprinkle a pinch or two (about 1/4 teaspoon) of incense (e.g. resin, dried herbs, etc.) directly on the hot charcoal, you can use a metal tongs or teaspoon for this. The incense will start to burn. Be careful not to put too much incense on the charcoal or it could smother it and you will have to start over. For a greater intensity of smoke and aroma, help its burning by blowing lightly or better yet using a feather or fan. Do not hold the record in your hand when it is turned on as it can burn. To maintain freshness, opened rolls should be resealed and stored in a cool, dry place. Effective storage will ensure rapid ignition and long burn time.
