Your Astral Candle Colour Chart
Sign/Primary Colour/Secondary Colour
Once the basic candle is done you can add to it. You can make yourself an astral candle for example, for a money spell, and add green drips and dollar signs on top of your basic astral colours. Or any colours and signs appropriate to the spell you are doing. You should burn it for at least 15 minutes to be effective for spellwork.
Astral candles can be used for many rituals until they are all burned. They should never be discarded, but either stored safely, or allowed to burn out after the last use.
