Why Your Authentic Pizza Oven Cracks and Why It’s Completely Normal

Welcome to the world of Authentic Pizza Ovens, where tradition, craftsmanship, and culinary excellence come together to bring you an unparalleled cooking experience.

If you’ve recently purchased one of our ovens or are considering making one a part of your outdoor kitchen, you might have some questions or concerns about the integrity and durability of these beautiful, handmade pieces.

One common question we often encounter is about cracking:


Why do Authentic Pizza Ovens crack, and should you be worried about it?

First and foremost, let us put your mind at ease. Cracking in our ovens is entirely normal and to be expected. These cracks are purely cosmetic and do not affect the oven’s functionality or structural integrity.

Let’s delve into why these cracks occur and why they are an inherent part of owning an Authentic Pizza Oven.


Understanding the Nature of Authentic Pizza Ovens

Our ovens are meticulously crafted by hand using traditional techniques and high-quality refractory materials such as brick and mortar and of course our own International patent Rockwool insulation exclusive to our ovens only.

Each oven is unique, with its own distinct characteristics, adding to the charm and authenticity of your cooking experience. However, the very nature of these materials and the processes involved in creating these ovens contribute to the inevitable occurrence of cracks.

Handmade Craftsmanship and Material Characteristics

The materials used in constructing our ovens—brick, mortar, and other refractory elements- are chosen for their excellent heat retention and durability. When you first light your oven, these materials undergo a significant transformation.

As the oven heats up, the bricks and mortar expand. When it cools down, they contract. This natural expansion and contraction can cause small cracks to appear over time. This is physics.


The Curing Process

Most of the cracking will occur during the curing process and the initial few fires. The curing process is crucial as it involves gradually heating the oven to drive out any moisture trapped within the walls.

As the moisture evaporates, the materials settle and adjust to the heat, leading to the formation of cracks. These initial cracks are part of the oven’s natural acclimatization and are a sign that it is becoming seasoned and ready for regular use.


Design and Heat Dynamics

Our ovens are designed with a specific structure that includes a dome shape and a chimney flue. The dome is wider at the back and narrower at the front, where the chimney is inserted. This design optimizes heat circulation within the oven, ensuring your pizzas and other dishes cook evenly and efficiently.

However, it also means that certain areas, particularly around the chimney flue and the facade, are more prone to cracking due to the differences in heat distribution and the expansion and contraction of materials.


Chimney Insert and Temperature Variations

The chimney insert is made of stainless steel, a material chosen for its high heat resistance. However, stainless steel also expands and contracts with temperature changes.

This natural behavior of the material can contribute to more prominent cracks around the chimney area and the facade of the oven. It’s simply the law of physics at work and a normal aspect of the oven’s design and functionality.


Managing and Minimizing Cracks

While it’s impossible to completely prevent cracking in your Authentic Pizza Oven, there are steps you can take to manage and minimize the appearance of these cracks:


Proper Curing

Follow the recommended curing process as closely as possible. Gradually increase the temperature over several days to ensure the oven dries out evenly and thoroughly. This slow and steady approach helps minimize the formation of larger cracks.


Closing the Door Between Fires

When not in use, close the door to your oven to prevent moisture from getting inside. This simple step can help reduce additional moisture-related cracking and protect the oven from environmental factors.


Regular Maintenance

Inspect your oven regularly and address any significant cracks with additional mortar if desired. Since our ovens are handmade with brick and mortar, you can easily apply more mortar to fill in cracks as needed, ensuring your oven remains aesthetically pleasing and structurally sound.


Using ULTRA FIRE for Superficial Cracks

For those who have our white dome ovens and wish to cover the superficial cracks for a cleaner aesthetic, we recommend the use of ULTRA FIRE. This product is specifically designed to adhere to the surface of refractory materials, providing a smooth finish that covers up cosmetic cracks.

ULTRA FIRE is easy to apply and will help maintain the pristine look of your white dome oven while preserving its unique character and charm.


Embracing the Beauty of Imperfection

One of the most charming aspects of owning an Authentic Pizza Oven is its unique, handcrafted nature. No two ovens are exactly alike, and the cracks that develop over time are a testament to the oven’s journey and seasoning.

In many European cultures, these cracks are celebrated as signs of a well-loved and well-used oven. They add character and authenticity, making your oven a true reflection of traditional cooking methods and artisanal craftsmanship.
