I have recently come across a few pieces of pyrex with the name James A Jobing on them. I cant seem to identify them. Is there anywhere i can post more pictures to get them ID'd ?

Pyrex was made by James A Jobling, sometimes shown as JAJ on pieces as well. Your pieces look like industrial/laboratory glassware rather than domestic items - my other half (a former industrial chemist) tells me the large globular one on the right is a reaction flask and it would be used the other way up and the other two pieces look like holding flasks of some kind . Someone on the board may be able to add more about them. Can you add individual pics of each item please?

More pics posted here for bighammerfan (I guess that's a footie ref rather than a DIY one!!!) ;D

this one seems to have everyone baffled :o

Found a book that talks a bit about Pyrex and laboratory testing, FYI-Click Here (http://books.google.ca/books?id=89w4kyQqQXcC&pg=PA357&lpg=PA357&dq=pyrex+laboratory+glass&source=bl&ots=5pdozYepxG&sig=iyHqUlTDjcKIWtHeBuArsrhegcc&hl=en&ei=OtwHStHaJ4jOMsW1mdMC&sa=X&oi=book_result&ct=result&resnum=6#PPA358,M1)

They are obviously laboratory or pilot plant glassware. These things were possibly made to order so may never be identified. They do date to before 1973 when Jobling was bought out by Corning, the actual owner of the Pyrex trademark and patents. Hence newer UK Pyrex no longer has the JAJ mark. Jobling only ever made Pyrex under licence. We aren't puzzled, it's just there is no more information to be had unless you know where they came from.
