Bunker refractory clay shell for wood-fired ovens
Bunker refractory clay shell for building wood-fired ovens, pizza ovens and bread ovens for domestic or professional use.
Handcrafted and fired at 1050°C for 8 hours, this top-of-the-range 8 cm thick kaolin shell will be the key component of your wood-fired oven, combining strength and thermal inertia.
It is available in 70 and 80 cm internal diameters.

👉 Fireclay is the "premium" material for building a traditional wood-fired oven. Indeed, the major asset of kaolin is its exceptional thermal inertia since it can store a massive amount of heat and release it slowly: once the fire has died down or been pushed to the side, the shell keeps giving off a gentle, constant heat.
✅ Another advantage, and no small one: its resistance to thermal shock! Unlike natural stone or standard concrete, which could crack, refractory clay is designed to withstand sudden temperature changes. It does not degrade despite repeated heating and cooling cycles: its very thick 8 cm walls will give it durability and a long service life.
✅ It also has a low coefficient of expansion, which limits the appearance of major structural cracks.
✅ Finally, a well-built clay oven is an investment for several decades: it is not affected by corrosion and stands up very well to the abrasion caused by logs and pizza peels rubbing against it.
Choosing a Bunker refractory clay shell will give you a great freedom in the design and construction of your pizza oven: you will create a unique piece you can be proud of!
Can't decide between the single-piece shell and the "Bunker" shell? Their main difference is wall thickness: 5 cm for the single-piece shell versus 8 cm for the Bunker shell.
What effect does this have on the oven's performance and use? The 8 cm thick shell will take longer to heat up and store heat, but will release it over a longer period, ideal for those who want to cook pizzas, then bread, and then slow-cook dishes for many hours, or for professionals who need the oven to stay hot for evening service.
