There is a number of publications that deal with the complexities of Dutch
bricks often called Overijselsteen. The key work is in Dutch, (naturally)
J.H. Hollestelle 1976 De steenbakkerij in der Nederlands tot omstreeks
1560. Gysber and Van Loon.
 
In addition information about bricks in VOC shipwrecks is available through
Green, J.N., (1977),
The A.V.O.C. Jacht Vergulde Draeck wrecked Western Australia 1656. British
Archaeological Reports, Supplementary Series 36, Oxford.
 
and
 
Green, J.N., (1989)
The AVOC retourschip Batavia, wrecked Western Australia 1629. An excavation
report and catalogue of artefacts.
British Archaeological Reports International Series No. 489.
Both of which ave reference material to bricks and their manafacture and use.
 
I hope this is of some use
