Hollow porcelain plates authentic

Box 4 hollow porcelain plates.
I am hunting for old, outdated porcelain, to which I breathe new life by laying large flat colors and a golden touch for a singular, chic and arty set!
I work the traditional technique of painting on porcelain which once fired is for food use.
The parts may have slight traces of wear but neither cracks nor chips.
Hollow plates seem to me particularly suitable for new culinary practices (pasta, ramen, salads ...) authentic
