How to Prevent Cracking on Your Pillar Candles: A Comprehensive Guide

Pillar candles can add a touch of elegance and warmth to any space, but there’s nothing more disappointing than discovering cracks in these beautiful creations. Cracking can occur due to various factors, including temperature changes, poor quality wax, and improper handling. In this guide, we’ll explore effective strategies to prevent cracking on your pillar candles, ensuring that they remain stunning and intact.


Pillar candles are not only sources of light but also works of art that can enhance the ambiance of any setting. To maintain their aesthetic appeal, it’s crucial to understand the reasons behind cracking and implement preventive measures.

Understanding the Cracking Phenomenon

Cracking in pillar candles can be attributed to the contraction of wax as it cools. This contraction occurs unevenly, leading to visible cracks on the candle’s surface. To prevent this, selecting the right type of wax is paramount.

Choosing the Right Wax

Opt for high-quality wax that is designed specifically for pillar candles. Beeswax and soy wax blends are known for their stability and resistance to cracking. Avoid paraffin wax, as it is more prone to cracking due to its brittle nature.

Optimal Pouring and Cooling Techniques

The pouring and cooling process significantly impacts a candle’s structural integrity. Pour wax at the recommended temperature and avoid pouring too quickly. Allow the candle to cool gradually and naturally, preferably in a draft-free environment.

Hard waxes like beeswax will crack if poured too hot and rapidly cool.

Temperature and Storage Considerations

Extreme temperature changes can cause pillar candles to crack. Store your candles in a cool, dry place away from direct sunlight and heat sources. Avoid placing them near windows or heating vents.

Adding Fragrances and Dyes

While adding fragrances and dyes can enhance your candles, it’s essential to use products designed for candle making. Incorrect additives can affect the wax’s composition and increase the likelihood of cracking.

Importance of Wick Selection

The size of the wick matters. A wick that is too large can cause the candle to burn too hot and crack, while a wick that is too small can lead to incomplete burning. Follow wick size recommendations for the diameter of your candle.

Avoiding Rapid Cooling

After the candle has solidified, avoid moving it to a cooler environment too quickly. Rapid temperature changes can create stress on the wax, resulting in cracks.

Proper Candle Maintenance

Trimming the wick to an appropriate length (about ¼ inch) before each burn can prevent overheating and subsequent cracking. Additionally, keep the candle free from dust and debris.

Decorative Wraps and Holders

If you’re using decorative wraps or holders, ensure they are not too tight. Tight wraps can compress the wax as it cools, leading to cracks.

Addressing Uneven Burning

Uneven burning can cause stress on the candle’s structure. To prevent this, allow the candle to burn long enough during each use so that the wax pool extends to the edges.

DIY vs. Professional Candles

While DIY candles are a creative endeavor, professionally-made candles often undergo stringent quality control. If you’re consistently facing cracking issues, consider investing in well-crafted candles from trusted sources.

Rescuing Cracked Candles

If you discover cracks in your candles, all hope is not lost. You can try melting the surface slightly with a heat gun and smoothing it out with a gentle touch. However, prevention remains the best approach.

Preventing Cracking in Special Conditions

If you live in an area with high humidity, consider using a dehumidifier in your candle storage space. Humidity can affect the texture of the wax and contribute to cracking.


Maintaining the integrity of your pillar candles and preventing cracking requires attention to detail throughout the candle-making process. From choosing the right wax to implementing proper cooling techniques and storage, each step plays a crucial role in ensuring your candles remain exquisite and crack-free.


  • Can I use any type of wax for pillar candles?
  • While you can use various types of wax, it’s best to opt for high-quality wax specifically formulated for pillar candles to minimize the risk of cracking.
  • Why is the cooling process so important?
  • The cooling process allows the wax to solidify evenly, reducing the chances of stress-related cracks.
  • Should I avoid adding fragrances to prevent cracking?
  • No, you can add fragrances, but make sure to use ones designed for candle making to maintain the wax’s integrity.
  • Can I fix a cracked pillar candle?
  • Yes, you can try gently melting the surface and smoothing out cracks with a heat gun, but it’s better to focus on prevention.
  • What if I live in a humid area?
  • If you live in a humid area, using a dehumidifier in your storage space can help prevent cracking due to changes in humidity levels.
