Please would someone who has the Jobling Pyrex book please have a look for me and report back on the dates of the first two Jobling Pyrex marks, together with what evidence for those dates is cited by the author(s).
The first is the simple "JP" mark, not often seen. The two letters were run together so it looks like a "J" with an added bulge on the top right. We have Janet's mother's EPNS mounted toddy glass with this mark acid etched on the bottom.
The second is the "JAJ" over a crown mark, usually with "MADE IN ENGLAND", seen moulded on most Pyrex sold secondhand here in Britain. The basic deco style* "JAJ" element of this is shown in a PG advertisement of 1 September 1933, reprinted in Baker & Crowe — the earliest date I have found so far.
I would also be interested in whether the authors prefer an overlap, a gap, or an instantaneous changeover from one to the other. This last is very popular with tidy-minded glass historians, but I have yet to find concrete evidence ever cited for it, so you always have to treat it with a little suspicion.

* The "JAJ" in the PG ad. has always looked to me more Charles Rennie Mackintosh (A&C or Modernist) than Deco. The version that actually appeared with the crown on the glass was a little milder.

There's no clear indication if/when these marks are discussed, so without reading the entire book it's hard to tell you. There is just one trademark shown and that is the crown over the word 'Pyrex' and that is dated 1953. I've read the portions on the earlier years quite closely as Chance, Orlak and Harold Stabler are mentioned, but cannot recollect any markings being mentioned.
Good book though (Pyrex - 60 Years of Design, ISBN: 0905974093) and can be purchased relatively cheaply online.

Realise this question was raised 7 years ago, but wondered if anyone has any answers as to dating the 'JP' Jobling Pyrex trademark. I am running a volunteer project at the science museum cataloguing a large quantity of these pieces, so any info on this would be very gratefully received!
Thanks

quoting from the Andy McConnell edited Miller's '20th - Century Glass' p. 200 - published 2006 ……………………………. this may be of some interest to the above request, and the wording as it appears in the caption reads ...............….
""Three differing logos were applied to British made Pyrex. The first, with the JP (Jobling Pyrex) monogram and PYREX MADE IN ENGLAND within a circle, was used 1921 - mid - 30s. This was followed by JAJ (James A. Jobling) above a crown and MADE IN ENGLAN.
The simplified PYREX logo, designed by Milner Gray of the Design Research Unit, was introduced in 1953. The disappearance of the JP/JAJ monogram reflected the end of the Jobling era after the family sold its interest to Pilkington in 1949. The cartoon KING PYREX figure was created by TIM and used for promotional purposed during the 1950s.""

Dear Paul,
Thank you very much for your response - that's incredibly helpful. I will try to get my hands on a copy of the book.
Thanks again,
Rupert

hi Rupert - I can of course send you a pm email - outside of the GMB - with pix showing the images in this volume - and would avoid you needing to buy said book. If acceptable to you, send me a message via my email at left hand side, and we can then resolve.

Thanks! Will do

I've got a red snowflake pattern dish with only the crown logo on it. No jaj or jp.
I haven't paid much attention to the marks, I just pick up the nice old Pyrex I can use, and I like the red stuff with snowflakes or gooseberries.

If I was going to purchase pyrex, I would love to find the Golden Thistle (of course), but apparently it is very rare.

I've never seen that, Carolyn. But if I do, I'll grab it for you, promise.
I have a fondness for the vegetables pattern when it's not the red stuff.
I'm never sure if my Pyrex comes under my glass collecting or my kitchen equipment collecting. ;D

Definitely fits under my Scottish Kitsch. You're very sweet, I would be more than happy to reimburse you for the purchase and the shipping.
