Thanks for the measurements of the bowl. I think we are at cross purposes, but not to worry I've sorted it out, I think. You gave me measurements for the Chinese covered bowl and this appraisal is for the blue bowl marked "Semi China" England. Your photo just shows the side (and another of the bottom) but it should look like this one? (if you click on the blue letters it will automatically bring up the picture) And is about 8" across and 3.75" high? If very different, please let me know.
(1) Willow fruit bowl,
This is a nice example of an English Staffordshire blue transferware bowl in the timeless and ever-popular "Willow Pattern" allegedly designed by Thomas Minton in about 1780, adapting for English tastes his own interpretation of what a Chinese pattern should look like.
Josiah Spode is attributed with producing the first printed versions of the "Willow pattern" in the 1790s. The composition is loosely based on a Chinese fairytale that was supposed to have inspired Shakespeare's Romeo & Juliet. The swallows (not doves -my own minor correction to the story in the following link) flying in the sky above the bridge are the reincarnated souls of the two star-crossed lovers.
Here's the full willow pattern story.
Blue Willow became enormously popular, particularly because of the romantic story that was associated with it and every English pottery produced their own version of it through the years.
This one marked with the trade name "Semi China" in a blue double-lined lozenge belongs to Ridgways of Shelton, Stoke-on-Trent, and dates to the first quarter of the 20th century. The backstamp has not transferred fully. It should look like this (if you click on the "this" it will pull up a picture of the mark)
As for value, this bowl would have a full retail price (if you saw it for sale in an antique store) of €175. This is also the replacement value for insurance purposes.
(2) Belleek clam shell tray (roughly 15'" x 14")
This beautiful porcelain tray has not travelled very far, or if it has, it's returned home close to where it started life. It was made at the Belleek porcelain factory in Co Fermanagh, Ireland's preeminent china maker for well over a century and a half, and still going strong.
The pattern is known as "Tridacna" from the scientific name for the giant clam upon which the shape is loosely modeled.
The mark is what's known as Belleek's "Second Black Mark" a logo they used from 1891 - 1926, so this piece is rising 100 years old or more.
This tray is a bit of a 'holy grail' for Belleek collectors as it goes with a cabaret tea service in the same pattern and so often the tray is missing or damaged.
Yours has a full retail/replacement/insurance value of €2000.
I do hope this helps!
PS If you rate me by clicking on the stars (which is how JustAnswer pays me -at no extra cost to you) and open another question, I'll continue with the next two. Thanks. R
