OK, I took some photos of the actual pot that I received. There are irregular sections of the outside that have a shiny gray appearance, sort of steel or lead looking. You see them in real life by moving the pot around in the light till they show up. The metallic looking spots are actually shinier than they look in these photos and are not as immediately obvious. I tested the pot for lead and it came out negative.
The color in the vendor's photo is more true to the pot, since I had to tweak color balance and contrast quite a bit to make the problem areas evident in the photos. Here is the best I good do with the lid:
One side and the floor of the interior are markedly lighter in color than the rest. This may have the same cause as the color differences in the exterior, but sometimes it looks almost like the interior was painted and one side got less or no paint. Arrows point out the dividing line between light and dark.
One of the strainer holes had a blob of clay plugging it. I was able to remove the blob with a toothpick and a wire, but I have not seen this sloppiness in any of my 16 other pots, many of which were in the same price range.
Finally, there was a rough edge with some extra clay that should have been removed at some point before it got to me. Like the plugged hole, I was able to fix this. I shaved it off pretty well with an Xacto knife, but it is just another sign of sloppy work.
I paid $16.90 for this pot plus shipping from China, so it is not like it was expensive. If it had been a $4 or $5 pot from Chinese Teapot Gallery, I would have expected this, but the C T G products that I have seen are much higher quality! This makes me think the Yunnan Colorful vendor is selling pots that may have a real value of 50¢ or so at an enormous mark up.
Also, as I mentioned earlier, two pieces that I ordered arrived broken due to thoughtless packing.
I have nothing against inexpensive pots. All I am saying is Chinese Teapot Gallery and several other tried and true places seem to be much better sources than Yunnan Colorful, based on my experience.
After testing for lead and boiling it and finding that the color does not come off on a white cloth, I think I may go ahead and use this pot, since I do like the shape and appearance of it, but it will get only occasional use. I am too distrustful of it after seeing so many little defects.
