Fire brick approved for food contact? - Forno Bravo Forum: The Wood-Fired Oven Community
Re: Fire brick approved for food contact? Fire bricks are not considered food safe because they are porous. How any bugs could survive 400 C is beyond me, but the regulators have different criteria. A wooden oven door is also not in the food safe category because wood is porous.

r/pizzaoven on Reddit: Pizza oven wall materials, food safety?
July 24, 2023 -
Hello there,
We're investigating pizza oven materials and looking to build a small portable oven, which quite a slim inner wall..
Should we be concerned with the type of materials used for inner walls, clearly firebricks are seen to be safe, is clay a good material also? How about refractory cement? Is there a specific kind, does it matter, am I over thinking the food safety aspect?

Natural Clay is excellent. Good heat retention and absolutely safe. Just need to account for the expanding/contraction that takes place when heating and cooling. :)

Toxicity of Firebricks Used in Ovens
For toxic metals to be leached into food or drink they need to be present and loosely bound in the crystal or glass matrix of the ceramic. Where complete melting has occurred there is a better chance that metals are a secure part of the matrix but only if the glass has a balanced chemistry and is not itself toxic (e.g. lead glass). However in the case of fire bricks, very little if any glass development has happened, only sintering (the bonding of the matrix by changes in the mineralogy (and therefore shape, size and surface) of particles associated with the heat treatment).

The Top 5 Reasons To Use Fire Bricks When Building A Pizza Oven - Littlehampton Bricks and Pavers
September 4, 2024 - You would be hard pressed to find an Italian -or any nationality- brick oven enthusiast who would suggest using anything but fire bricks for the inside of the oven! No toxic additives You need to keep in mind that you’re going to be using this oven for cooking, not just to look at! Because standard bricks vary so much in colour and style, this means that they also vary greatly in the ingredients used to make them. Although here at Littlehampton Brickswe make all our products using natural clay, the same can’t be said for all manufacturers. To be sure your food is going to remain chemical-free it’s always a better option to use fire bricks.These are just a few of the many reasons it is a much better idea to avoid using house bricks and pavers for the inside of pizza ovens.
