12. De Ham - The Ham / Le Jambon (workshop active from 1640 - 1726), Achterom, east side. 'Names of houses' file mentions it in 1636 as a brewery and in 1745 as a faience workshop.
No image of a mark of this workshop is available to this author at the moment.
Masters & apprentices
All masters and apprentices working at this workshop had to be inscribed in the Delft St Luke Guild Book. In 1877 this book was published in a 120 page text by Obreen. In 2002 this text has been scanned and is now available and fully searcheable on this internet site. See the yellow field on top; first click the heading Delft Artists & Patrons and then click Obreen. The full text is in Dutch. Spelling varies; in order to find masters or apprentices of a faience workshop (plattielbackers, plateelbacker, platielbacker) search for the letters "plat".
A serious collector of Delftware will attempt to identify and date the object. On Delft blue plates and other Delftware objects such as jugs, a potters mark may give a first indication. One should always treat potters marks with caution. Marks must be considered as just one indication.
A correct dating of Delft blue tiles is much more complicated; there is usually no potters mark on a tile. Regarding tiles the serious researcher may rely instead on one of the following sources: 1) company archives 2) the date set by actual tiles still found in situ in a building which itself can be dated, 3) the design or image ; the best documentation collection is the archive of 70.000 photos in the Nederlands Tegelmuseum in Otterlo near Arnhem, The Netherlands, 4) the size, thickness and other technical characteristics. An excellent source book with thousands of illustrations and technical discussions is this recent book in Dutch and English, written by Jan Pluis (see the cover to the right).
Only these Delft potteries produced Delft blue tiles: Rouaan, later known as Het Lage Huys; De Lampetkan, De Vergulde Blompot, De Ham, De Dissel, De Paeuw / Paauw, De Roos, De Grieksche A.
