Yes that is very interesting. I have never seen a 269 pattern in Pearline, straight uranium pieces are quite common. Do the dishes have the registered design number in the base?
These dishes certainly show that Primrose Pearline was made past 1908. We also know that in the years immediately after WW1, Davidson were not making any coloured glass. It was not until 1922/23 that colours such as purple, amber and green were reintroduced. This suggests an end date of Pearline of around 1914. There is no evidence that it was made post WW1. Which is a shame as could you imagine what a 10 inch 279 vase would look like in Pearline?
From the evidence we have unearthed in the Newcastle archives it looks as if Davidson were not making Uranium glass in the mid to late 1930s (we looked for what chemicals Davidson were buying and their production records), which suggests that manufacture of Uranium (as opposed to Pearline) ended sometime in the 1920s/ early 1930s. This could have been as a result of the depressed economic conditions. 20th century styles which often appear in uranium include the 269, 695 and the 279 vase.
Incidentally, in the 19th Century Davidson called their uranium glass Canary.
Anne, thank you for the info on the peg tankard. I will follow that up. Any thoughts on a lump bottom? Some of the early yearly suites include a lump bottom in their inventory, so it must be a piece of domestic glassware.
