Why can't some factory marks be identified?


Throughout the world there have been many pottery & porcelain factories and studios; some only lasting for just a few months and many for well over 100 years.


Some potters owned their own freehold factories and many others rented their potteries which meant that a succession of firms would use the same works. Also it was quite common for firms to share the same pot works or for a larger company to let out a smaller section of his works for economic reasons to another potter who wouldn’t clash with the owner’s wares.


Some potters purchased ‘blanks’ from other manufacturers and put their own decoration on them - sometimes these wares carried two backstamps.


Consequently there is some uncertainty when trying to trace details of a particular mark for many factories.
