Take a pot of melted lead, the surface is all gray and crappy looking from the oxide. Now skim that oxide with a ladle, ooh, it's all shiny looking. But by the time you get the ladle all the way across the pot, and dump the oxide, the surface has gone gray again. It happens less quickly to solid lead, of course, but it won't be shiny very long.
Now if you write with lead oxide, the line won't be black like graphite, but gray. Strangely, if you write with it in Canada it won't be gray, but grey.
