Some very slight color refraction around the handle, most likely some settled dust from age. There are also two darker spots or inclusions from the firing, also shown but not too obvious as they are close to the handle.
The pitcher measures 7-3/4"t x 6-1/2" in diameter plus the handle projection. Questions welcome and thanks for looking.
