How do you melt a candle that u want to keep?

It's not advised to melt a candle and repurpose it, as scented candles contain fragrances and chemical dyes which may give rise to harmful fumes once melted that you would want to keep. Candles manufactured for decorative purposes may also be made using hazardous additives. Moreover, it is often difficult to completely extract every ounce of the wax. So you might as well enjoy them in their intended form and repurpose jars in creative ways afterward by recycling or upcycling. This approach will ensure health safety and help the environment too.
