A Chinese imari vase with cover, Qing dynasty, early 18th Century, with Johanneum mark N:145x.

Johanneum Mark - Inventory marks added to porcelain belonging to the collection of August the Strong (1694-1733) of Saxony. The first inventory was made in 1721.

The inventory numbers are painted in black, or cut through the glaze with a glass cuter's wheel and blackened. In some cases the number have only been drawn in ink and have by natural causes washed away. In rare cases, in old and museum collections, they can be found inside lids and sometimes on unglazed porcelain bases.

A second inventory list of the porcelain collection at Dresden was made between 1770-1779. The second list comprises five volumes recording the original information of the 1721 inventory and the alterations depending on new acquisitions were added.
