My Yixing green and brown teapot

Here is my yixing teapot with a big crack on the side. Can anyone tell me more about it, has the mark underneath the lid, mark on base, writing on the side. It's not smooth to the touch.

Thank you

I can tell you it has a huge crack in it... does it go all the way through to the inside? Does it still hold water without leaking?

 

No it doesn't go to the inside, yes it holds water
