What Happens if You Overheat Soy Wax?

What Happens if You Overheat Soy Wax?

If you overheat the wax, it will begin to evaporate and burn out. Soy wax vapor is not harmful, toxic, or allergenic, unlike paraffin from petroleum products. If inhaled for a long time, it can cause headaches. Therefore, it is best to make candles in a well-ventilated room.

Keep in mind that working with hot wax requires caution. The wax burns at +180°C or + 356 °F (the exact temperature depends on the type of wax) and can ignite if heated over an open flame. Theoretically, this could cause a fire, and you could get serious burns. If possible, use professional equipment for candle-making at home.

Can You Overheat Candle Wax?

Paraffin melts at about 60 °C (140 °F), beeswax – at 63 °C (145 °F), and it is not recommended to heat it above 80 °C (176 °F). Soy wax is best held at temperatures up to 83 °C (181 °F). To melt old candles, you may need to heat the mass to 85 °C (185 °F). Anything above these temperatures will be considered overheating.

If you buy a semi-finished product for candles, carefully read the instructions on the package. It will indicate the optimal temperature at which it should be melted.

Melt the wax or paraffin in a water bath, and then there is no risk of heating it to a burning temperature. If you decide to warm the wax quickly, over an open fire, or on a hotplate, be sure to use a thermometer to control the mixture’s temperature.

What happens if you overheat soy wax?

Slight overheating of soy wax leads to lumpy solidification. If the heating temperature is much higher than recommended, the soy wax may change its chemical composition, and soy wax separation will occur. The lower the pouring temperature, the faster and more even the wax will cure.

The melting point of soy wax begins at 50°C (122 °F). Do not heat it above 83 °C (181 °F). Remember that manufacturers may have different recommendations for maximum heating temperatures for soy wax.

Is Soy Wax a Toxin?

Soy wax is completely natural, gives clean burning, and is non-toxic (safe for children, pregnant women, and animals). The wax is also used in various industries: cosmetics, pharmacology, and perfumery.

Why soy wax and not paraffin? Paraffin is a byproduct of oil; when the oil is refined into diesel fuel, gasoline, and hundreds of other products, it is the paraffin that remains in the residue.

Yes, soy wax is more expensive, but it burns 30% longer than paraffin. It has no smell and soot when burning. And since the soy wax itself is almost odorless, it gives place to the aromatic components in the composition of the candle.

Once you have lit the candle and the wax has melted, the fragrance begins to spread in the room. This only takes 10-15 minutes. Therefore, the soy candle can rightly be called a quick room fragrance, along with the interior spray. Also, soy wax is biodegradable, making it environmentally friendly.

What is the Difference Between Melting the Wax or Burning the Wax?

The melting of paraffin is a physical change since only the physical state changes – from solid to liquid, and burning is a chemical change. During combustion, paraffin reacts with the oxygen in the environment and forms carbon dioxide and ash.

Flammable paraffin usually ignites at the following temperatures, depending on its melting temperature and the hardeners added. Paraffin wax without additives: 199°C (390 °F). Paraffin with additives: 249°C (480 °F). Beeswax begins to evaporate at 120 °C (248 °F) due to the thermal degradation of its components and burns at 300 °C (572 °F).

We recommend using wax melters to melt the wax.

Why is Waxburn an Irreversible Reaction?

Wax melting is reversible since solid wax melts when heated, and molten wax becomes solid when cooled. Melting wax is a change that can be reversed, and wax can be used again, while burning wax is an irreversible process. We can’t combine all the wax-burning products to get the original candle. Therefore burning of wax is a change that cannot be reversed.


Thanks to the simple creation technology and a large selection of materials for work and decoration, everybody can now open a miniature “candle factory” at home, which will not only bring pleasure from creativity but may also become an additional source of income.

The advantage of this type of hobby is that this activity is not difficult, not boring, and beautiful results can be obtained fairly quickly. For these reasons, making candles at home will be enjoyed by and within the power of needlewomen of all ages.

It is very important to follow the technology of making candles. Otherwise, you can not only ruin the candle but also get burned. So, first, be careful, and then start experimenting and create unique candles that will turn a simple dinner into an unforgettable romantic evening.
