this looks like De Klauw mark, but I wouldn't know if it's a true one or a fake one. Check out the different variations of this mark here https://delftsaardewerk.nl/merk/een-klauw

This is the mark of "Chambre des Peintres", workshop in the Boch factory located in La Louvière, Belgium, according to the info on the website of the Royal Boch (current name of the factory), it was started in 1870-s and was operating till 1892, but the production of Delft-inpsired pottery didn't finish in 1892, as based on the catalogue of the factory of 1899, they still offered a large number of items. https://www.royalboch.com/fr/pages/histoire/

Thank you! I understand how the techniques are different, thanks for the "melts" with the glaze explanation, that makes it more specific for me. I probably need to look at more confirmed overglaze dishes to learn to see the difference, because for now it's not at all obvious to me, as a noob in pottery. Looks pretty much as shiny as newer marked with years De Porceleyne Fles items I have. I could say I do feel a bit of relief, but it's not like I could feel the drawing... only some points where the pigment is the darkest, feels a bit like "bump". Could it be something like this? https://delftsaardewerk.nl/bekijken/voorwerp/carla-van-wilgen/8279-bord… 
I am a bit confused about your comment re diameter, would appreciate if you could share a bit more on the sizes. Is there a link or reference I could learn more from?
Many thanks again for your inputs.

Thank you for sharing, how do you see it's not underglaze? I would like to learn. To me it looks very much like on this plate, and the size is almost identical. https://delftsaardewerk.nl/bekijken/voorwerp/tetim/8376-t-fortuyn-plate
and then by the same logic, this plate would also be not underglaze? https://delftsaardewerk.nl/bekijken/voorwerp/tetim/8375-plate-societe-c…

thank you. How do you see it's not underglaze?

💜 thank you so much for sharing this!
