I have been keeping this to myself until I was sure, but there is a lot more Chance glass out there to find. Much of this has not been identified because it was produced for third-parties. The most prominent was Crystalex of London, for whom it produced a set called 'Flora', and the details I found were in the pressed glass records. The items were fruit bowls, dishes, and a footless sugar bowl and footless cream jug. There may be other items in this range.
Another surprise was some "Star Footed Bowl" (and Fruit dish) produced for Jules Lang who I believe was a distributor and exporter. There must be a few about as the numbers produced was 98,000 and 155,000 respectively.
Many other items are 'fridge boxes, lids, drip trays for Electrolux, Kelvinator, and so on. But there were a few stock ash trays, including one 'Club' model (my words) measuring a mammoth 10-in diameter! The other ash trays are: Five-sided, Round and Square models, which also came with 'Pimpled' and 'Prismatic' bases.
Some were also used from stock and decorated to the clients' specification: sprayed with colour; transfers affixed; gold rims, etc.
Some of the descriptions are enigmatic to say the least: "Large Bowl. Blackberry Pattern" and "Drape Bowl", a Goblet for Kenwood(!), "Portman" bowls, sugar basin and jug... but what these are I have no idea yet.
Another oddity is the "Plain Jug" made for Lowit. note it is a "plain" jug, so we assume there is no identifiable pattern. However, this is decorated with these very precise instructions:
Apply 1 crinkle band to base 1¼" wide and 1 crinkle band ¾" above. ¾" wide. Apply one ¼" gold line between crinkle bands, 4 gold lines above crinkle and apply gold to rimPerhaps we have been wafting past this jug before, assuming it wasn't Chance. One ounce of gold only decorated 30 jugs, so it should stand out - now I'm sure I've seen one of these before somewhere... Anyway, this is why I directed people from the
Crinkle posting by Keith.
One surprising item was a Britannia Bowl. Platinum Rim - yup, it actually used platinum. The records even show a single ounce of platinum would decorate 600 bowls. Ever seen a Britannia "Jam Pot with Lid"? Nope, me neither... but there are/were 130,000 of them somewhere

This level of detail is a little, ahem, anal, I suppose, but it does help to form a much rounder picture than before. However, if anyone does spot any of these items, I would really appreciate a heads-up, or I will purchase them if found in a charadee shop, car-boot, etc.
Please e-mail me privately. I am still compiling this list - it is long - but I think that's the main thrust of it.
Now you know why Chance Additions is taking so long

Oh, and I had lunch with Sir Jeremy Chance today, plus four others. Sir J made a presentation to Laura Brett, who has been doing the sterling work at the archives, of some Fiesta plates and bowls... all decorated in gilt on blue-flashed glass. The pattern was Roset!
