Whether you are buying or selling, knowledge is the key to success. There are some excellent sites where you can learn about your special interest.
On my about me page http://members.ebay.co.uk/ws/eBayISAPI.dll?ViewUserPage&userid=lychap you will find my three favourite sites for research.
- The Great Glass site has a wealth of information on all types of glass and the photo library is excellent.
- The Potteries site is mainly for Staffordshire Potteries with plenty of information including backstamps.
- The other glass site is mainly about vaseline / uranium glass, again with many photos.
These may change from time to time so keep checking.
Ebay offers a vast range of pottery & glass and learning to recognize the genuine article from the reproduction and lookalikes can save you disappointment, and there is always the chance you will pick up a bargain if you know what you're looking for.
