Srudio pottery mark JC?

Could you plz help id this bowl? It' s made from white clay and marked with JC in square. I found a few bowl with JC signature but the clay or marks are different.

I like the way how its glazed and decorated. i first thought of japan but because of jc mark i think it is most likely european made. maybe a dutch ceramist since i bought this in NL
Any info about this type glazing, maker is much appreciated

Thanks

 

Yes, the combination of the type of clay and the glaze looks very Dutch.
