Natasha's Nifty Candles uses 100% soy wax. Soy wax is biodegradable and cleans up with plain old soap and water. Soy wax has a lower melting point than paraffin wax and because of this, soy candles will burn slower or longer than paraffin candles. Soy wax burns with zero petro soot, creating petro soot-free candles. Let's not forget, it's healthier as well for you to breathe in.
"Paraffin Wax releases toxic fumes when burnt, which has contributed to its fall out of favor. In 2009, a study by South Carolina State University found that burning paraffin wax candles give off harmful fumes (toluene and benzene) which are linked to asthma and lung cancer in long-term use. Soy candles, in the same research, were not found to emit toxic chemicals. It is also reported that frequent lighting of multiple paraffin candles in an unventilated space could lead to problems commonly associated with paraffin wax: irritation of skin and respiratory tract. This study garnered widespread controversy on the effects of paraffin wax versus that of soy wax, resulting in an increased demand for soy wax candles. Crude oil, being the origin of paraffin wax, is considered highly unsustainable due to it being a non-renewable resource. It has also been the cause of a slew of environmental calamities, in oil spills, damage of natural habitats, and climate change."

To re-purpose a container:
Boil enough water to fill the cup up leaving 1/4 space at the top.
Pour it in the container and watch as the heat melts the wax causing it to bubble to the top.
Leave this to cool for about 2-3 hours or overnight if you would like.
Once the container has cooled down you can remove the solid wax at the top and pour out the water.
Apply pressure and pull out the wick along with the bottom tab.
Wash out the container with soap and water and re-purpose your container.
