Hey sydney. Scented candles making is the best business and very profitable if you have good marketing skills. 1kg of wax goes for 1k. Scents you can use fragrance oil coz they're cheaper and has strong scent as compared to essentials oils. Fragrance oil you can easily get them from Eastleigh or house of leather. As for the glass get the ones with the lids they prevent the scent from fading. Get a heavy glass to avoid breaking when burning. The glass ranges between 80-100 or get the alcohol glass for 2 bob each and take to glass cutters they do it with 15-30 bob. As for the wick you can get them either from the shops that sell candles or check YouTube and make on your own. A little research will help you not to mess with measurements of every ingredient to be used. As for colors you can use dyes or food color or melt the crayon pens. Most people use paraffin wax and soy wax. Pls note its fragrance oil not fragrance perfume, perfume doesn't burn it will clog the wick. To standout in the market bring something that's not common ie creating unique scents and using silicone moulds to make different shapes of candles.wishing you the best as you start your journey in your new business
