| May 2, 2018 at 6:58 | comment | added | Neeraj Deshmukh | The example in the answer gives a quasi-projective scheme with quasi-affine components. Are there non-quasi-projective examples? Or is such a scheme necessarily quasi-projective? | |

| May 1, 2018 at 16:02 | comment | added | Jason Starr | I discussed this example years ago with Ravi Vakil. I very much believe this example has appeared before on MathOverflow (maybe as an example of a quasi-projective $k$-scheme whose global sections $k$-algebra is not finitely generated). | |
