Kalk-Style Porcelain Vintage Vase Marked with 2 Blue crossed Arrows

Kalk porcelain is a type of German porcelain that was established in Cologne in 1882 and stopped production in 1930 after merging with another factory. The factory that followed, Porrzellanfabrik Kalk G.m.b.H closed in 1971, but many company have since copied the blue marks. The 4 numbers under the blue crossed arrows are more of an indication that this was not the original Kalk. It is still very collectible and lovely.
