The short answer
de Buyer publishes more about its carbon steel than anyone else in the category: composition as 99% iron and 1% carbon, thickness per size, weight per size, cooking surface diameter, handle material and fixing, country of manufacture and first-use instructions. It publishes no oven maximum, no dishwasher guidance and no warranty term. Both halves of that are notable, and both are on the product card. The MINERAL B PRO at 3 mm is the pan to buy if you are committing to carbon steel.
What this review checks
Published construction, oven ceiling, induction compatibility, dishwasher guidance, handle design, warranty terms and exclusions, country of manufacture, and what the brand declines to state. We have not cooked in any of it. The method is here.
de Buyer is the most interesting brand on this site to audit, because it is simultaneously the most and least forthcoming. It publishes things nobody else does and omits things everybody else provides.

First use
Wash thoroughly with hot water and a scrub brush to remove all beeswax - no soap needed; then oil and heat until the oil begins to smoke lightly
Composition percentages and per-size thickness are genuinely rare. Most carbon steel is sold with a diameter and a photograph.
The cooking-surface figure deserves particular credit. Carbon steel pans are steeply sloped, so rim diameter overstates the usable base by around two inches - a gap explored in what size carbon steel pan to buy. de Buyer is one of the few makers that lets you compare the number that matters.
What it does not publish
No oven maximum. None, anywhere, for the MINERAL B PRO. Retailers list 500F, which is a retailer figure rather than a manufacturer one, and we do not treat it as a de Buyer specification.
No dishwasher guidance. The answer is obviously never - it is bare steel and it will rust - but the maker does not say so.
No warranty term. On a pan sold as a lifetime object, an unstated warranty is a conspicuous silence.
None of that makes it a worse pan. Bare seasoned steel has no coating to fail and almost nothing that can go wrong that a scrub and a reseason will not fix - see restoring rusty cast iron, which applies to carbon steel almost unchanged. It is a documentation gap, and this site counts documentation gaps.
The Heat Stop handle, which is a real design
de Buyer publishes "Riveted, Heat Stop" for the MINERAL B PRO: a handle geometry designed to slow the conduction of heat up from the pan body. The contrast is Matfer Bourgeat, whose black steel pans use a riveted steel strip with no heat break at all, conducting pan temperature straight into your hand.
Neither is wrong. Matfer's is a commercial design that assumes a towel and gives you an unbreakable pan. de Buyer's costs more and is friendlier at home. It is the single biggest practical difference between the two brands and it is worth deciding on before buying, because it is not something you get used to.
Bare steel with no coating and no enamel. The only things that can go wrong are rust and neglect, and both are reversible.
The beeswax, which is the real barrier to entry
French carbon steel arrives coated in beeswax to prevent rust in transit, and it has to come off before the pan is usable. de Buyer publishes the instruction plainly: hot water and a scrub brush, no soap needed, then oil and heat until it smokes lightly.
It takes about twenty minutes and produces a smoky kitchen, and it is the step where people give up - particularly on a pan they were not sure about. If that is likely to be you, buy pre-seasoned: the Lodge carbon steel pan is usable on arrival. The full method is in seasoning a carbon steel pan.
The lines
MINERAL B and MINERAL B PRO. The mainstream carbon steel range. The PRO differs mainly in the handle and finish.
Blue steel. Heat-treated carbon steel with a blue-gray finish and a small head start on seasoning.
Copper lines. A separate and much more expensive business, and not covered on this site.
Bakeware and tools. Also sold; the carbon steel pans are what the brand is known for and what this review is about.
Who should buy it, and who should not
Buy it if
You have decided on carbon steel, you will do the beeswax removal and the seasoning, and you want the best-documented pan in the category with the friendliest handle. Check price on Amazon.
Skip it if
You will not dry the pan on the burner after every wash. Carbon steel rusts overnight, not eventually. Cast iron is more forgiving, cheaper and arrives ready to use - the honest version of that argument is in is carbon steel worth it.
Verdict
de Buyer is the brand this site would design if it made cookware: it publishes composition percentages, per-size thickness and weight, and a factory country, and it declines to publish three things it should. The pan is excellent and the documentation is both the best and the most frustrating in the category.
de Buyer and the pans it is compared against
Two 3 mm French pans, one pre-seasoned alternative, and the wok if the shape you want is a bowl rather than a skillet.

de Buyer MINERAL B PRO Carbon Steel Fry Pan, 11 in
3 mm, 4.6 lb, published as 99% iron and 1% carbon, with a riveted Heat Stop handle. More documentation than anyone else offers.
Best for: Someone who wants cast-iron searing without cast-iron weight
For carbon steel, yes, if you will maintain it. de Buyer publishes composition as 99% iron and 1% carbon, thickness and weight per size, cooking surface diameter and a Heat Stop handle design - more than any competitor documents.
›What oven temperature can de Buyer carbon steel handle?
de Buyer publishes no oven maximum at all for the MINERAL B PRO. Retailers list 500F, which is a retailer figure rather than a manufacturer one. In practice the limit is the seasoning rather than the steel.
›Why is my de Buyer pan covered in wax?
Beeswax, applied to prevent rust in transit on bare steel. de Buyer's published instruction is to wash it off thoroughly with hot water and a scrub brush - no soap needed - then oil the pan and heat it until the oil begins to smoke lightly.
›What is the difference between de Buyer and Matfer Bourgeat?
Mostly the handle. de Buyer publishes a Heat Stop geometry designed to slow heat traveling up the handle; Matfer uses a riveted steel strip with no heat break, which gets as hot as the pan. Both are 3 mm at 11 inches.
›Does de Buyer cookware have a warranty?
No warranty term is published for the MINERAL B PRO, which is a conspicuous silence on a pan sold as a lifetime object. In fairness, bare seasoned steel has no coating to fail and almost any damage can be scrubbed back and reseasoned.
