I often wondered if Plum Run didnt get its color changes due to being heat treated rather than patinazation??very nice frames,thx for sharing your plum run artifactsjeff a said:thanks everyone, the neat thing with plum is that it patinates to reds and yellows the fresh flint from the quarrie is gray almost like a dark hornstone , as it patinates even farther it starts to get a dull black with red banding you can pretty much tell the age by the color
