A fine and early Worcester patty pan, painted in underglaze blue with the "Bare Tree and Speared Bird" pattern, with trailing leaf sprays on the exterior and a painter's mark on the bottom. This pattern appears to only have been used on patty pans, and is also the only other pattern, aside from the full "Mansfield" pattern, that has a "Mansfield" pattern border.
More important is that the patty pan with this pattern, uncommon in itself, was made in two forms. The more common is shallower, has an everted rim, and came into use around 1758. The more common type is shown in profile in the 6th picture, and is not part of this listing, though it is available for sale. The gem offered here is earlier, taller, with more sharply sloping sides, and the rim is not everted. It is considerably rarer than the other form.
What are now called patty pans were originally called tart pans. They were sold in matching or nested graduated sets, made of porcelain, glass, or pottery. Their original purpose has been attributed to potted meats, pates, or pickled items.
This pan is in superb condition, with no chips, cracks, or restoration. The enameling is sharp, bright and without loss. Any flaws that appear to be in the photos are due to light reflections. The height is 1 3/4", with a diameter at the top of 4 1/8", and a foot diameter of 1 5/8".
