Whether you are building a professional pizzeria oven, a commercial wood-fired furnace, or a backyard outdoor pizza oven, the performance of your oven depends heavily on the quality of the pizza oven bricks you choose.
Highland Refractory—founded in 1990 with 1100+ employees and full refractory production lines—manufactures premium fire bricks specifically designed for wood-fired pizza ovens, meeting the global demand for durability, thermal stability, and consistent cooking performance.
This ultimate guide explains everything you need to know about pizza oven bricks, including:
What fire bricks for pizza oven are made of
Technical performance indicators
Why fire bricks outperform regular clay bricks

How to choose the right brick grade
How to install and maintain pizza oven bricks
Why Highland Refractory is the preferred supplier for OEM pizza oven brands worldwide

Pizza oven bricks—also known as fire bricks or refractory bricks—are specially engineered bricks made from high-alumina and silica refractory materials capable of withstanding:
Continuous temperatures of 1200–1400°C
Direct flame exposure
Rapid heating and cooling cycles
Mechanical abrasion from wood, ash, and tools
Highland Refractory pizza oven bricks typically contain:
| Component | Percentage | Function |
|---|---|---|
| Alumina (Al₂O₃) | 30–40% | Heat resistance, structural strength |
| Silica (SiO₂) | 50–60% | Thermal stability & bonding |
| Fe₂O₃ | <1.2% | Prevents thermal warping and discoloration |
| Refractory aggregates | — | Improves mechanical wear resistance |
These raw materials are fired at high temperatures (>1500°C) to create a dense, durable brick that performs flawlessly in pizza ovens.
Highland’s fire bricks deliver superior physical and chemical performance compared to standard clay bricks or concrete blocks.
Ensures the oven can reach authentic Neapolitan-style pizza baking temperatures:
🔥 450–500°C cooking surface
🔥 900–950°C dome temperatures
Without cracking, melting, or deforming.
Pizza ovens are heated and cooled repeatedly. Highland fire bricks withstand rapid temperature changes without spalling.
No cracking
No surface flaking
No internal fractures
This results in longer oven lifespan and reduced maintenance.
The bricks absorb heat, store it, and release it evenly—critical for:
✔ Even cooking
✔ Consistent temperature stability
✔ Fast recovery time between pizzas
This is why pizza cooked on fire bricks has:
Crisp bottoms
Evenly melted cheese
Perfect blistered crust (“leopard spotting”)
Highland bricks maintain stability even under:
Heavy dome weight
Long-term high-temperature exposure
Repeated thermal cycling
This keeps the structure safe and stable for decades.
Wood-fired ovens release:
Alkali vapors
Ash
Organic acids
Melted fats
Fire bricks from Highland resist chemical attack, preventing:
Structural erosion
Surface decay
Color changes
Reduction in lifespan
Bricks do not deform, bulge, or shrink excessively at high temperatures, keeping the dome shape perfectly intact.

| Property | Value |
|---|---|
| Alumina Content | 30–40% |
| Bulk Density | 2.1–2.3 g/cm³ |
| Apparent Porosity | 22–24% |
| Cold Crushing Strength | 250–300 kg/cm² |
| Modulus of Rupture | 80–90 kg/cm² |
| Thermal Conductivity | Low—ideal for heat retention |
| Refractoriness Under Load | 1500°C |
| Linear Change (1350°C) | 0.2% |
These specifications are engineered specifically for pizza ovens and culinary heat systems.

| Feature | Fire Brick | Regular Red Brick |
|---|---|---|
| Max Temperature | 1400–1550°C | 600–800°C |
| Thermal Shock | Excellent | Poor |
| Heat Retention | High | Medium |
| Absorbs Moisture | Low | High |
| Durability | 10–20 years | <2 years |
| Food Safety | Yes | Possible cracking |
Regular bricks will crack under pizza oven temperatures. Fire bricks will not.
Medium-duty fire bricks → Best for pizza ovens
High-density bricks → Best for commercial continuous firing
Low-density bricks → Better insulation but lower strength
Highland provides:
Standard rectangle bricks
Curved arch bricks
Tapered dome bricks
Floor bricks
Custom CNC-cut bricks
Light buff
Yellow
White
Cream
Red refractory options
Color does not affect performance but affects branding and aesthetic.
Use only high-temp refractory mortar:
✔ High-alumina mortar
✔ Air-setting refractory mortar
✔ Premixed mortar for pizza ovens
Never use cement—it will crack at high temperatures.
Lay bricks tightly
NO mortar between cooking-surface bricks
Sand/fireclay mix leveling layer
Ensure smooth surface for even cooking
Options:
Pompeii dome
Barrel vault
Igloo style
Hybrid steel + brick designs
Bricks should be staggered for dome stability.
Preheat oven slowly (avoid cold → hot shock)
Clean ash regularly
Avoid pouring water on hot bricks
Check for surface cracks annually
Use oven door for better heat retention
With proper care, Highland fire bricks last 10–25+ years.

70% Alumina Fire Brick is a high-performance refractory material, composed of approximately 70% aluminum oxide (Al₂O₃). Manufactured from high-quality bauxite or synthetic raw materials, these bricks undergo high-pressure molding and high-temperature firing to achieve superior durability. With excellent resistance to high temperatures, thermal shock, and chemical corrosion, 70% Alumina Bricks outperform ordinary clay or lower-alumina bricks in strength, refractoriness, and erosion resistance. These characteristics make them an ideal choice for industrial furnaces, kilns, and other high-temperature equipment. Compared to ordinary clay bricks or refractory bricks with 50%–60% aluminum content, 70% alumina bricks offer higher refractoriness, better compressive strength, and stronger erosion resistance. This makes them a mid-to-high-end refractory material with excellent cost-performance, suitable for industries that demand reliable, long-lasting, and heat-resistant linings. Highland Refractory provides high-quality 70% alumina bricks that meet international standards, ensuring stable performance for diverse industrial applications.
Corundum - mullite brick refers to high purity or pure raw materials made of refractory products.
