The artisans who created tile designs are largely unknown; however, a few, like Pytter Grauda of Harlingen, can be identified.
As demand increased, tile factories began to re-open.
Several factors contribute to determining when and where an antique Dutch tile was made, including: the type of clay used, the thickness and texture of the tile -- early tiles are usually thicker and rougher than later versions -- the glaze, the subject of the design, and the maker's marks.
Rare tiles command the highest prices, but with few exceptions, the names of most historical ceramicists are unknown.
In the sixteenth century several factories were established in a number of Dutch towns which among their items produced “Majolica”.
This "Majolica" was made with a tin-glaze and found its origins in Italy and Spain.
