Lithographic limestone is hard limestone that is sufficiently fine-grained, homogeneous and defect free to be used for lithography. Geologists use the term lithographic texture to refer to a grain size under 1/250 mm. The term sublithographic is sometimes used for homogeneous fine-grained limestone with a somewhat coarser texture.
Famous quotes containing the word limestone:
“Peering, I heard the hooves come down the hill.
The posse passed, twelve horse; the leader’s face
Was worn as limestone on an ancient sill.”
—Allen Tate (1899–1979)
