This is the fourth installment of the Pan Series. The previous installment, #3, was the Misen Carbon Nonstick teardown (https://www.craftoverlocation.com/the-toolbelt/misen-carbon-nonstick-teardown). This one comes from the other end of my own ranking. On November 2 I said it plainly: Strata and De Buyer are my top tier. That is the voice anchor here. No extra story added. This teardown is about whether the construction holds that place.
The pan here is the 11-inch Mineral B Pro, reference 5680.28, $145 on De Buyer's US store. The photos are De Buyer's maker photos, authorized for use here. They are not photos of my pan.
The Construction
The body is iron 99%, carbon 1%. No coating. No clad layers. A single piece of iron-carbon, 3mm thick in this size, 11 inches across with an 8.3-inch cooking surface, 4.6 lbs. Made in France. Induction compatible; the maker also lists gas, electric, ceramic, and BBQ.
At 3mm this holds heat. It also holds weight. You feel both in the same lift.
The finish as shipped is beeswax — transit protection, not seasoning. It washes off before first use. Underneath is bare iron-carbon you season yourself. It darkens and, per the maker, performs better with use.
Line pricing on the same page: 8-inch $110, 9.5-inch $120, this 11-inch $145, 12.5-inch $175. The carbon steel lines carry a lifetime warranty.
Why the Pro Handle and the 500°F Line Matter
Mineral B and Mineral B Pro get mixed up constantly. The difference is the handle, and what the oven will do to it.
The classic Mineral B has an epoxy-coated iron handle. Its oven use is short — about 10 minutes at 400°F max. That is a flash finish, not a roast.
The Pro has a cast stainless steel handle, riveted, with what De Buyer calls Heat Stop. The Pro line is oven-safe to 500°F. Still a limit — do not read it as unlimited. But it is a different pan in practice. You can start on the stove and finish in the oven without watching a clock on a handle coating. If a listing does not say Pro, do not give it the Pro's number.
The Seasoning Routine and the Care Burden
De Buyer gives the first seasoning as a short checklist, and this post carries it exactly as the maker states it. This is the save artifact for this installment:
1. Hot-water brush wash to remove the beeswax, no soap
2. Thin layer of high-smoke-point oil
3. Heat until it lightly smokes
4. After cooking: hot-water rinse, wipe, dry fully
5. Light oil coat before storing
The ongoing care is the same shape: rinse, wipe, dry fully, avoid soap, never the dishwasher, oil before storing.
None of this is hidden — the maker states it. Stated plainly, it is a burden you accept every cook. Miss the drying step and iron will tell you. The pan improves with use only if the use includes this routine.
The Drawbacks, Plainly
First, the work. Seasoning before first use, hand care after every use, no dishwasher ever. That is the category, and this pan does not exempt you from it.
Second, the weight. 4.6 lbs is heavy. One-handed tosses are work. For some cooks that ends the conversation, and that is a fair call.
Third, the ceiling. 500°F is better than the classic line by a wide margin, but it is still a ceiling.
Fourth, the start. The beeswax has to come off before you cook anything. Skip it and your first seasoning sits on transit wax.
Fifth, the price. $145 is not budget iron. You pay for thickness, for France, and for that stainless handle.
Verdict
Judged on Benton's Rule — materials, construction process, real-world longevity — this pan clears the first two without argument. Iron and carbon, 3mm thick, a riveted cast stainless handle, no coating to fail. Longevity is where the rule gets honest. The material will last; the lifetime warranty says the maker expects it to. Whether it lasts in your kitchen depends on whether the care routine lasts in your routine.
That is why it stays top tier here, with the drawback attached. Top tier does not mean effortless. Here it means the construction earns the work it asks for — if you will actually do the work.
