Product code: Cloisonne (masonry) tile the Porceleyne Bottle of a fantasy ship hot
This is a masonry tile from the Porceleyne Fles from Delft. These tiles do not have random framing, unlike the decorative tiles. They usually have a brown border. The intention of masonry tiles was that they were bricked in, e.g. in a wall between other tiles.
But this tile is hot completely cool because it has never been bricked in.
