How to treat bubbles in aromatic candles to achieve the best results

Aromatic candles express good taste and add a warm and more luxurious atmosphere in the place, but during the manufacturing process you may encounter some problems that affect their beauty or even their quality, such as air bubbles that leave clear traces on the surface or inside of the candle and thus affect its final appearance or the quality of combustion. But how can the bubbles in aromatic candles be treated?

What is the problem with bubbles inside candles?

Before we review the method of treating bubbles in aromatic candles, it is important to know what the problem is first, as it is one of the most annoying problems that can occur, as these bubbles usually appear in the form of tiny dots or even voids inside the body of the candle or on its outer surface, thus losing its elegance and reducing its appeal. Although the candle remains usable in this state, these bubbles give the impression that it is made inaccurately, and this affects its final appearance.

What are the causes of air bubbles in candles?

There are many reasons for bubbles to appear in aromatic candles, the most prominent of which are:

• Rapid or random stirring: When adding essential oils or color dyes and stirring quickly or randomly, this allows air to enter the mixture.
• Rapid pouring: Rapid pouring from a great height causes bubbles to form when the wax comes into contact with the walls of the mold or bowl.
• Moisture in the mold: Or even the cold surface of the mold causes air to be trapped when it comes into contact with the hot wax, thus causing these bubbles.
• Low wax temperature: When pouring candles at a low temperature, this prevents the air from escaping from the mixture easily.

Treating bubbles in candles

One of the most common defects that may spoil the final appearance of aromatic candles are air bubbles, especially when pouring them into glass or transparent containers. These do not usually represent one of the problems that affect the quality of candle burning, but they give an unpleasant impression when seeing the candles. So, how can bubbles in candles be treated?

Stir the wax gently and constantly

It is necessary to continue stirring the wax gently when adding perfumes and colors to avoid air entering and affecting the consistency of the mixture.

Pour slowly and steadily

It is important to pour candles into the molds from a low height, slowly and steadily, to reduce friction with the air and thus allow the wax to settle into the mold very smoothly.

Mold heating

It is necessary to warm the mold or vessel into which you want to pour the wax gently, especially in winter or humid places, to avoid sudden cooling and air trapping.

Light knocking on the sides

Immediately after pouring, be sure to tap lightly on the sides of the mold to help the small bubbles rise to the surface before the wax hardens.

Use a heat gun

After the candle has hardened a little, use the heat gun to melt the top layer and release the bubbles stuck to the surface.

Raise the wax pouring temperature slightly

But without the temperature exceeding the safe limit of 96 degrees Celsius (20 Fahrenheit), to keep the wax liquid for a longer period and give the bubbles a chance to escape.

Note the clicking sound

When heating candles, especially soy wax, listen for a crackling sound, which indicates the presence of trapped air that needs time to escape.

Why does wax change color?

Another problem that can appear in aromatic candles, such as air bubbles, is a change in the color of the wax. Color is the first thing that attracts attention, and you can notice some obvious changes in color, such as yellowing or fading, even if you do not add any color to it. Just as we know how to treat bubbles in aromatic candles, it is also important to know the causes and solutions to the problem of wax color change.

The color of the wax can change due to its exposure to environmental factors such as natural or artificial light, or the components of the perfume itself, especially those that contain vanillin or citrus oils. Methods that help solve this problem include:

• Use UV inhibitors. They act as a sunscreen to help protect the dyed wax from fading caused by exposure to light, but these inhibitors do not prevent changes caused by vanillin-rich perfumes.
• You can add a touch of ivory or cream color if you are working with a natural wax such as soy and the yellowing appears due to the perfume. This color works to neutralize the effect of vanillin and thus obtain a smoother, uniform color.
• The use of perfumes with high vanillin can be reduced if you do not find the previous liquids effective, or replaced with other perfumes that have less effect on the color.

What is the problem with holes inside the candle?

Sometimes, when the wax cools and hardens, some small gaps or holes appear on the surface. These holes result from air bubbles trapped inside the wax when pouring. If the surface hardens before the bubbles come out, it leaves behind voids that can reach a depth of 2 cm. Among the steps that help in solving them are:

Recasting:

Reserve a little of the pre-melted wax and then gently pour it onto the surface of the candle to fill the holes and level the top layer.

Using a heat gun:

If additional wax is not available, you can apply light heat to the surface of the candle using a heat gun to melt the surface layer and become even.

Treating bubbles in candles early:

When pouring candles, monitor the surface carefully and move it gently to release the air, and tap gently on the sides of the mold to speed up the exit of bubbles before they solidify.

Temperature control:

Pour wax at the appropriate temperature and heat the containers before use to reduce shrinkage and trapped air.
