2 shades of color inside a pot

[DailyTX]

Hi All, I picked up something interesting...it's a side handle zisha pot. It looks and feels like very fine zisha, most likely modern made. What I am not certain is the inside of the pot. It has tool marks but two different shades of brown. Anyone has idea why there are two shades? I appreciate any feed backs

Hi DailyTX,
Seeing this one, I hope it didn't cost much. By my experience as a local of the origin place,the uneven colors were likely caused by the author carelessly contaminated more than one type of clay when made it. usually they make teapots from different types of clays which have various colors after ignited(natural properties). or, the clay itself wasn't well aged or at poor quality. Usually this neutral seal(indicating no name of author) determines not so good on quality on raw material, techniques and fame. Sorry but this is true.

Definitely it didn't cost much at all because the seller didn't know what Zisha was, so the lip that came with the pot has different shade of color as well as different type of clay. I can tell the lip was a Yu Hua Long teapot lip that's much older than the teapot. the clay reminds me of Qing Shu Ni from 70s-80s. It's a good specimen for learning

Nowadays here in local internal business flow of zisha, the clay itself is much focused determining somewhat the value, then the finished technique and then the fame of author.
