Westmoreland Carolina Dogwood Marigold on Milkglass

Hello, this is a rather Unique piece of Carnival Glass! This is a Westmoreland Carolina Dogwood Marigold on Milkglass, which is a rare Base glass for the Carnival World. However the unique part about it is the interesting and I believe lovely Caramelized Interior. Carnival glass has iridescence which is applied to both the interior and exterior, the exterior obviously has some amazing carnival glass hues, however I am not 100% sure how the interior was produced to appear more like Caramel than anything else, I did however know that I had to have this when I saw it, as I love carnival glass but try to keep my collection small by only pursuing unique or rare examples. Thanks for looking!
