I own Baumalu pans, they are 2.2/2.3 mm thick cooper lined with tin. I mistakenly said that I own 5 pieces (I own 7) and they are really good. However, I take care of them properly (no high heat on an empty pan, hand washing, no metal spoons, etc.)
They come lacquered to avoid cooper tarnishing during shipping, the lacquer can be removed with a cotton embebbed with acetone and washing afterwards.
I don't know if the company has a website, they are suppliers to commercial equipment in France and the rest of Europe and as I said, they perform great. I purchased 5 of these pans in a shop near Poitiers in France, the other 2 in a Home Goods store in Michigan.
I also have 3 sauciers from Falk Culinaire that I bought at thier factory in Wespelaar, Belgium. These are 1.5 mm thick cooper with 0.2 mm SS and also are great, very similar to Mauviel since Falk manufactures the raw material (Cu+SS) for both products.
Seems like you are replying to somebody. I was also asked about directions to the Falk factory earlier, I already provided them in detail. With the decline of the Dollar I wonder how expensive they are now. Back 5 yrs. ago they were about 50/60% off USA prices.
