Candles are made with a beautifully creamy olive wax and cotton wicks, which gives an old world feel. Wax melts are made with a firm coconut wax.

Trimming candle wicks between burns will keep the flame a safe, predictable height, which in turn prolongs the life of your candle-- a win, win! Wicks should be trimmed to be about a quarter inch (1/4") in length.
Otherwise, flames can become too tall and unruly, containers can become very hot to the touch and burn you or surfaces, and your candle may burn down very quickly.

I use proprietary, perfume-grade fragrance oils which is a blend of essential oil and synthetic scent accords. I do not use pure essential oils for a multitude of reasons, the biggest being safety. Firstly, due to the concentration levels of pure essential oils, handling them can be quite dangerous and cause respiratory irritation and distress, headaches, rashes and burns/blisters, eye irritation or even blindness (if the oil got into your eyes).
Secondly, undiluted essential oils aren't meant to be burned and can give off toxic fumes.
This is a subject I have done a lot of reading and inquired with industry professionals. If you have any questions or concerns not addressed here, I am more than happy to do my best to answer them.

Denatured perfumer's alcohol, proprietary perfume-grade fragrance oils, and dipropylene glycol (DPG) which is a plant-based solvent that stabilizes fragrance oils and aids in perfume projection and longevity.

This could happen for a few reasons. If it is a lit candle, the size of the candle needs to match the size of the room. Smaller candles do well in more confined spaces like bathrooms, bedrooms, or offices. Larger and multi-wicked candles perform best in big open areas like living rooms or dens. Try leaving the room where the candle is, or going outside, and returning to see if it’s noticeable – you may have gone nose blind towards it, especially if you stayed in the room when it was lit! Some fragrances will naturally be more subtle than others.
If it is perfume, try spraying it onto clothes instead of skin (permitting it is not a delicate fabric). Fabrics have the best scent retention! Body heat and sweat can alter the way perfumes smell and skin friction can make them fade much quicker, so reapplying throughout the day is usually needed. Since fragrance usage and safety guidelines are re-evaluated yearly, it can cause once-permitted perfume scents that had true, long-wear staying power to be deemed unsafe. Obviously, this means fragrances and perfumery composition has changed greatly in the last 15-30 years, so those heavy hitters of yesteryear are likely not safe by today's standards. Alternatively, it’s possible it is anosmia and it commonly happens with amber and musky fragrances. This means you literally cannot and will not be able to smell or detect those types of scent notes. Fun fact: it’s genetic!
Bottom line, everyone’s sense of smell and preference is different.

All of my incense is hand dipped in a blend of proprietary, perfume-grade fragrance oil and dipropylene glycol to enhance scent projection and reduce soot, and then air-dried.
Each stick will burn for an hour, usually longer!
