 · Shale and slate are sometimes used interchangeably but the materials are not the same. Many of the items sold today for landscaping (flagstones retaining walls) and construction (chalkboards roofing tiles pool tables etc.) uses as "slate " is actually the much more inferior form—shale. Shale is sedimentary rock lightly compacted into thin crumbly layers.
