This massive hand beaten solid copper vessel resembles a fireplace pot, but the very large size would seem to make it impractical as a cooking pot - it weighs about 9 pounds. I suspect it's more decorative, like the copper tourist items made in Mexico in the first half of the last century. Though primitive in appearance, the copper is quite thick and the workmanship is good - the seam at the neck where the rim attaches is virtually undetectable.
The widest part of the pot is 15-1/2 inches diameter. Depth to the rim is more than 7 inches, and the swing handle adds another 6 inches to the height when raised. The rim opening measures 10 inches diameter. There is one shallow dent to the bulge, barely noticeable due to the textured hammer marks (second picture, just below and to the left of center). I tried to give an idea of scale in the last two pictures by posing the pot with a coffee cup, but to me it still looks smaller in the photos than in reality.
