Identifying 紫砂壶 product description (Calligraphy) I was gifted a 紫砂壶, and although I can read standard characters, I'm having a hard time piecing together this product description. Here is what I have so far, and I'm having to guess a lot:

五四三二一　
　　　　　　　
　大紫此作　一
二方砂壶品　二
？二？？說　三
？？？用書　四
茶？？原　　五
？堪？曠　　六
　及造？　　七
　其型？　　八
　藏古？　　九
　？樸？　　十


As you can see, I'm not very good at reading calligraphy.

Also, I am confused at why there would be a simplified version of 优 at the bottom if the rest is traditional?

藏價 is short for 收藏價值
The text has no punctuation mark and change column in the wrong places. Also mixing traditional and simplified characters (some in variant form) together. No wonder you can't get what it said.
