Ideally for this you should really make your own candle melt, so I’ll explain first a couple of ways how to do that and then, if you cannot do that, you can simply use a black candle (solid colour not dipped).
To make your own:
Ecosoy wax flakes (100g should be plenty for 2/3 melts) and 5g of black candle dye, or alternatively break off a black candle and melt it again. You can then pour it in a specific wax melt container or use rubber molds (THIS IS AN EXAMPLE ) Melt safely in a heatproof container (a Pyrex jug is fine if melting the wax over water or you can buy a more professional candle wax melting pot).
Whichever way you use once melted then add:
– dried rosemary ( a couple of pinches)
– 4 drops of mandrake oil
– a pinch of ground nutmeg
– 4 drops of rose essential oil
Let it set properly (usually overnight) then use by melting slowly in an oil burner. Once used you can easily take off the hardened wax by putting the burner in the fridge for about 10 minutes.
This is something I LOVE to do (please be careful though!) because although I love buying ready-made candles, it simply adds to the ritual of making “special candles” like protection ones or spell candles.
Why wax melts and not candles you may ask?? Well because they are EASIER to make and the end result is the same ;), enjoy!
