It was slate. No it's dust. At least where you whacked it.
You (all) recall my original query about a 1920 apartment house at 245 West 75th Street, with "one of the nicest details I've ever seen: at every fifth course, the masons laid the mortar with a continuous strip of copper right in the middle of the bed."
First, I should have noted that it is every fifth bed >>for the first two floors only<< which further supports my surmise that it is decorative, not functional.
Second, I took a hammer with me today, because I wondered if it might be lead, instead of oxidized copper. It's not. It's slate, very thin flats of slate.
