Candles 101 — Technical

What is the difference from C-1 and C-3?

NatureWax has two Container Blends that are called C-1 and C-3. The main difference between these waxes is that C-1 consists of a blend of Vegetable Oils, whereas C-3 is 100% Soy Based.

NatureWax C-1 performs better when it is poured at temperatures around 110 deg F. The C-3 Blend performs better when poured at temperatures closer to 160 deg F. Another feature about C-3 is that it has better glass adhesion than other soy waxes.

There is a lot of foaming/bubbles appearing in the wax — how can I resolve this problem?

One way to reduce bubbles from appearing in the wax is by heating the wax to 180 deg for a short time to let the trapped air escape. Be sure to not overly agitate the wax, because that may cause it to pick up more air.

The tops of the candles are very uneven and glass adhesion is nonexistent. How can I eliminate these problems?

Getting optimal Glass Adhesion with most waxes can be a tricky problem to overcome. For optimal glass adhesion, we suggest using our Naturewax C-3. It is a superior formulation that has the best glass adhesion in the industry.

Below are steps to producing candles that have better glass adhesion:

  • Pre-wash glassware for the candle since there may be a film or residue in the container causing poor glass adhesion.
  • Slightly warm the jar before pouring the wax; this is especially important during the winter months when the glassware is colder than normal temperatures. Glassware should be 70 to 80 deg F for best results.
  • Slightly remelt the top of the candle, less than 1/8 inch, to smooth out the top.

How is soy different than paraffin?

Paraffin Wax is derived from fossil fuels found deep within the earth. After refining processes take place, the bi-product you will have is paraffin wax. Although paraffin wax has been commonly used in candles, many consumers are looking for vegetable based alternatives.

Soy Wax comes from Soy Beans grown by farmers both in the USA and around the world. Soy Wax tends to have a more opaque appearance than paraffin, allowing some colors to appear more bold and vibrant.

How do I prevent cracking?

Circular Cracks in the top of the candle happens when the inside of the candle cools after the top has already cooled. (need to know how to solve this problem)

Linear cracking is typically due to the wax cooling to fast. By reducing the cooling rate of the wax you will reduce or eliminate this type of cracking.

Voids can also be a source of the linear cracking. By poking relief holes into the top of the wax and then doing a slight remelt of the top to fill in the voids can take care of this problem.

Both types of cracking can be reduced by allowing the wax to just fall to the side of the candle during cooling. Once the top of the candle has hardened, the wick can be gently straightened across the top to allowing the inside of the candle to cool. After the candle has cooled completely the top can be slightly remelted to fill back in the area where the wick had originally been.

Each Naturewax product has a Handling Instruction sheet that contains information on how to create the optimal candle system. Please see the Handling Instructions relating to your product for recommendations on the process you should use to make your candle perform beautifully.

What fragrances, wicks do you recommend?

It is important to remember that candles are systems and that it takes several different components to create a high quality & safe candle. Please visit the National Candle Association website at to get supplier information. They will be able to provide you technical assistance with their products.

What percentage of fragrance can I put into my candles?

Please see Handling Instructions for detailed information.

What is the melt point of a certain wax?

Please see Technical Data Sheet for detailed information.

What is the proper way to store NatureWax, i.e., heat and cold limitations

Please see the Storage & Handling Instructions bulletin for information on how to best store your waxes.

How long should my soy candle setup before I burn it?

Container Candles should setup for at least 24 hours. Pillar Candles should setup for 36 to 48 hours.

How far apart should my container candles be when cooling?

The candles should be spaced at least two inches apart during cooling.

Is NatureWax® soy wax food grade, kosher, etc.? Is it edible?

Please contact our Sales Team for more detailed information.

Can soy wax be used to make soap?

Yes, since soy is a triglyceride like the other oils that are used for soaps. Please contact our Sales Team for more detailed information.
