If you wish to make your candle appear as it has craters, you definitively have to use ice cubes ! While melting your paraffin, you'll prepare the mould, insert and fix the cotton wick and eventually add some coarsely ground ice cubes in the mould (up to 1/3 or half of the mould). When the wax is completely melted, you can add dyes and essential oils/fragrances and after a good 5 minutes of stirring you can pour the wax into the mould. Ice cubes will make the wax solidify very quickly and they will leave an empty space around them when they will melt. It's a very simple technique , but it gives a very peculiar shape to your candles!
