The earliest tin-glazed pottery in the Netherlands was made in Antwerp by Guido da Savino in 1512. The manufacture of painted pottery may have spread from the south to the northern Netherlands in the 1560s. It was made in Middelburg and Haarlem in the 1570s and in Amsterdam in the 1580s.[1] Much of the finer work was produced in Delft, but simple everyday tin-glazed pottery was made in places such as Gouda, Rotterdam, Amsterdam and Dordrecht.[2] The main period of tin-glaze pottery in the Netherlands was 1640-1740. From about 1640 Delft potters began using personal monograms and distinctive factory marks. The Guild of St Luke, to which painters in all media had to belong, admitted ten master potters in the thirty years between 1610 and 1640 and twenty in the nine years 1651 to 1660. In 1654 a gunpowder explosion in Delft destroyed many breweries and as the brewing industry was in decline they became available to pottery makers looking for larger premises; some retained the old brewery names, making them famous throughout northern Europe, e.g. The Double Tankard, The Young Moors' Head and The Three Bells.[3]
