1970s 50 ml #3 水平壶 (shuǐ píng pot) from http://jingteashop.com. This is part of a set of 12 (I only have #3 and #5) 内紫外红 (nèi zí wài hóng; see http://phyllsheng.blogspot.com/2006/11/ … -pots.html and / or http://houdeblog.com/?p=41 for more on this process, and a picture of another #5 pot). This morning, the #3 pot flew off the shelf when I was carelessly grabbing another pot. The lid broke.
The first picture is a contrast between the (unused) #3 pot and the (used) #5 pot, when both were intact. If you notice some minor brown areas on the #3 pot, I believe they're due to areas where the hong ni is thin, not to use / seasoning.
The color of the clay inside is much darker than in the previous post, even compared to the inside clay. Same lighting as the previous shot (specialized photo lighting, digital SLR, white-balanced) - somehow everything looks a little redder than it should, still.
