To make candles with a square shape.

To make these candles, we chose salmon coloring, and we got square candles with a salmon pink tone. Made in three different sizes. Here are the materials and quantities we have used,

  • Paraffin wax, approximately 1,800 grams.
  • Fluorescent salmon coloring
  • The aromatic essence of tiaré and passion fruit flower.
  • Waxed wick, 10-11 cm
  • Spray release agent
  • Guide rod 3 mm
  • Square molds for 10 cm 7×7, 15 cm 7×7, and 15 cm 7×7 candles.

You can make candles of the same diameter and different heights with the same mold simply by filling the mold more or less. As for the colorant, choose the one you like the most from the wide range of liquid candle dyes. An exotic mixture of two essences will leave a pleasant aroma, Tiare flower, together with passion fruit. Prepare your own mixture of essences!

Let’s get to work

Square Candles

Always use containers and utensils that you will not use for any other purpose. It would be helpful to have special containers that are only for candles.

Step 1. We begin by melting the paraffin at 65º; for the three candles we made, we need 1,800 grams of paraffin. Meanwhile, prepare the mixture of your chosen essences in a small glass. Let your sense of smell guide you, adding one essence after another until you get the aroma you are looking for.

Step 2. We will work on a tile; this way the candle will cool faster and not stick to the surface. Once we have the liquid wax, transfer it to a more convenient container. Add drops of colorant and mix, adding color until you get the desired shade. Add drops of essence and mix again.

Prepare the mold, and spray release agent inside and on the tile where you will place the container.

Step 3. Pour some paraffin into the mold and let it dry for a few minutes to seal the bottom. Place the metal rod in the center of the mold in the paraffin. Finish filling the mold to the height we want the candle to be. Allow to cool completely; this step will take a few hours.

Repeat the same process to fill the rest of the molds. You can play with the amount of color to make candles of different shades.

Step 4. cut the wicks to the size each candle needs. Remove the metal rod and thread the cut wick through the center hole. Melt some paraffin, turn the candle upside down and fill the hole where the wick comes out. This will fill in any bulge and hold the wick in place. Allow to cool for a few minutes and the candles are ready.


How do I choose the right mold for my square candle?

Choosing the right mold for your square candle can significantly impact the final product’s quality, look, and ease of removal. Here are a few factors to consider:

  1. Material: Molds can be made of different materials such as metal, plastic, silicone, or glass. Silicone molds are flexible and make it easier to remove the candle once it’s hardened. Metal molds are durable and heat-resistant but can be more challenging to work with for beginners. Plastic molds can be cheaper but may not withstand higher temperatures as well.
  2. Shape and Size: Obviously, you’ll want a mold that’s square-shaped. However, the size of the mold will determine the size of your finished candle, so consider how large or small you want your candle to be. Also, consider the depth of the mold as this will affect how long the candle will burn.
  3. Wick Hole: Some molds come with a hole at the bottom for the wick. This can make it easier to position your wick correctly, but it also means you’ll need to seal the hole to prevent wax from leaking out.
  4. Smoothness: A smooth interior surface on your mold will give a smooth finish to your candle. Textured or intricate molds can create interesting effects, but they can also make it more difficult to remove the candle.
  5. Ease of Cleaning: Consider how easy the mold will be to clean after each use. Wax can be tricky to remove completely, so choosing a mold that’s easy to clean will save you time and effort.
  6. Durability: If you plan to make candles regularly, you’ll want a mold that can withstand repeated use. Silicone and metal molds are usually the most durable options.

Remember, the type of wax you’re using may also affect your choice of mold. Some types of wax may stick to certain mold materials more than others.

What type of wax should I use for square candles?

The type of wax you use for your square candles can depend on your personal preferences, the look and burn characteristics you’re going for, and your budget. Here are brief descriptions of the most common types of candle wax:

  1. Paraffin Wax: This is the most commonly used and cheapest type of wax. It holds scent and color well and is easy to work with, but it’s a petroleum byproduct, which raises some environmental concerns.
  2. Soy Wax: This is a natural, renewable, and biodegradable wax made from soybean oil. It burns slower and cooler than paraffin wax, resulting in a longer-lasting candle. Soy wax is also known to produce less soot. However, it may not hold color and scent as well as paraffin wax.
  3. Beeswax: This natural wax produced by bees has a pleasant, natural honey scent. It burns longer and produces less soot than paraffin. It’s usually more expensive and harder to find than other waxes, and it may not hold additional scents as well.
  4. Palm Wax: This is another natural wax made from palm oil. It’s hard and brittle, making it great for molded candles like square candles. It also has a nice crystalline or feathery effect when it cools, giving the candle a unique look.
  5. Coconut Wax: This is a softer, creamy wax that burns slowly and cleanly. It holds scent well, but is usually mixed with other types of wax to improve its hardness and melting point.
  6. Blend Waxes: These are mixtures of different types of wax, designed to take advantage of the benefits of each. For example, a soy-paraffin blend might provide the long burn time of soy wax with the scent and color retention of paraffin wax.

In general, for square candles, you may want to consider a harder wax like palm wax or a wax blend that has a higher melting point to maintain the shape of the candle. However, the choice ultimately depends on your specific needs and preferences.

How do I prevent bubbles from forming in my candle?

Air bubbles in candles can occur due to various reasons such as temperature fluctuations, rapid cooling, or improper stirring. Here are some tips to prevent bubbles from forming in your candles:

  1. Pour Temperature: Pay attention to the temperature at which you pour your wax into the mold. If the wax is too hot, it can cause air to be trapped, leading to bubbles. Each type of wax has a recommended pouring temperature, so make sure to follow those guidelines.
  2. Slow Cooling: Allow your candles to cool slowly. Rapid cooling can cause shrinkage and air pockets. You can wrap a towel around your mold to insulate it and slow down the cooling process.
  3. Stirring Technique: When mixing in your fragrance or color, stir slowly and gently to prevent air from getting trapped in the wax.
  4. Preheat Your Mold: If you’re using a metal or glass mold, consider preheating it before pouring in the wax. A warm mold can help the wax adhere better to the sides and reduce the chance of air pockets forming.
  5. Top Off: If you see a dip or air hole forming in your candle as it cools, you can do a second pour or “top off” to fill in these gaps. Just heat a small amount of wax and pour it into the dip to level off the candle.
  6. Wick Placement: Make sure the wick is properly centered and secured. A loose wick can cause air to get trapped around it.

By taking these precautions, you can minimize the chances of air bubbles forming in your square candles.

How long should I let my candle cool and harden?

The time it takes for a candle to cool and harden can depend on a few factors, including the type of wax used, the size of the candle, and the ambient temperature.

As a general rule, most candles should be left to cool for at least 24 hours. This allows the wax to fully harden and set. Larger candles may require more time, potentially up to 48 hours.

It’s important to let your candles cool at room temperature in a place free from drafts, direct sunlight, or other heat sources. Rapid cooling can lead to problems like cracking or frosting in the finished candles.

Remember, patience is key when making candles. Rushing the cooling process can impact the quality of your candle, including its burn time and scent throw. Even if the candle looks solid on the outside, the inside might still be soft or molten. Always ensure the candle is completely hardened before moving or burning it.


Making square candles can be a fun, creative, and potentially profitable endeavor, but it requires some planning, knowledge, and practice.

Always follow safety guidelines when making candles. This includes careful handling of hot wax, using a heat-safe container for melting wax, never leaving melting wax unattended, and keeping your work area free of flammable materials.

Making perfect candles often requires some trial and error. Don’t be discouraged if your first few attempts aren’t perfect. Learn from each batch and adjust your methods as needed.

By keeping these points in mind, you’ll be well on your way to making beautiful, high-quality square candles. Happy crafting!
