Extra-hard red firebrick, 40×40×5 cm, for professional hybrid ovens

The 40×40×5 cm red refractory brick is a professional-grade brick designed for use in hybrid pizza and bakery ovens, where heat can be generated from multiple sources (wood, gas or electric heating elements) and temperature profiles are more complex than in a traditional wood-fired oven.

Thanks to its refractory composition and 5 cm thickness, this brick offers high heat storage capacity and uniform heat distribution, allowing for consistent and stable baking even with rapid switches between fuel types. The structure of the red baking stone helps to limit localised overheating peaks on the baking surface, improving the uniformity of baking between the flame zone and the peripheral areas, a fundamental aspect in high-performance hybrid ovens. It is the ideal choice for pizzerias and restaurants that wish to exploit the versatility of the hybrid oven whilst maintaining high and consistent cooking standards.

Key features

• Dimensions: 40×40×5 cm, a size suitable for the cooking decks of professional pizza ovens.
• Colour: red, typical of certain refractory clay mixtures used for oven decks.
• Use: base/cooking surface for professional hybrid ovens (wood + gas / wood + electric).
• Material: fired refractory brick/clay, made from a mixture of selected raw materials and fired in a kiln to ensure mechanical strength and stability at high temperatures.
• Thickness 5 cm: professional thickness, with high thermal inertia and the ability to withstand intensive working cycles.
• Compatibility: suitable for wood + gas or wood + electric hybrid ovens that require a refractory surface capable of operating effectively with different heating methods.

Advantages in a hybrid oven

• Management of mixed temperature curves: designed to work with combined heating (wood, gas, electric), limiting excessive temperature fluctuations between different areas of the chamber.
• Uniform heat distribution: helps reduce areas that are too hot or too cold on the surface, improving the evenness of pizza baking in high-temperature hybrid ovens.
• Stability at high temperatures: suitable for professional ovens that can reach up to 400–500 °C in hybrid mode, typical wood+gas models for pizzerias.
• Suitable for repeated baking: the 5 cm thickness ensures a good ‘flywheel effect’, useful for continuous service with many consecutive bakes.

Installation and usage advice

• Installation: place the base on a suitable support (e.g. a bed of sand or refractory materials recommended by the oven manufacturer), avoiding non-refractory adhesives or mortars that cannot withstand the temperatures of professional ovens.
• Running-in: carry out gradual heating cycles to dry out any residual moisture and stabilise the material, especially in ovens operating at high temperatures and in combined modes.
• Hybrid mode management: where gas burners or heating elements are present, avoid extreme thermal shocks (very rapid temperature changes or contact with cold liquids) which can stress the baking stone.
• Cleaning and maintenance: use suitable brushes or scrapers to remove flour residues and impurities, without applying liquid detergents directly to the hot surface.

Intended use / target

The 40×40×5 red refractory baking stone is suitable for:

• Pizzerias and establishments using hybrid wood + gas or wood + electric ovens that require a refractory surface optimised for this type of operation.
• Installers and technicians who build professional hybrid ovens or convert traditional ovens by adding gas burners.
• Bakeries and catering establishments requiring flexibility in oven management (e.g. rapid gas/electric start-up and wood-fired finishing).
