Durock manufacturing artifact
I’ve seen this for years but it never really registered until a few weks ago when I was rebuilding a section of floor (see photo below)– Durock brand cement board has a marking that repeats randomly across it’s surface. It’s that “7″ shaped line all over the sheet in the photo above. And it looks to me like that gesture is a scratch from the machinery the sheets move on and across in manufacturing. It’s a rough gesture but it’s identical everywhere it appears so it appeals to me as this very mechanical artifact– almost a little map– of the material’s creation.
