No fade, no run, no erase, no disappear
Here is a blog post that features a set of tests for a pen with which to write your lab notes, if you plan on them being around through some sort of accident after they are written. Several different kinds of pens are tested, and the winners of permanent writing are discussed.
Comments are welcomed.
