Would you please tell me how to use the simple method to identify shale brick, clay brick?

Answer:

Shale density is small, weigh in hand, feeling relatively light, clay brick is high density, relatively heavy.
Is the shale as raw material for high temperature baked bricks using shale and coal gangue, clay brick not dense surface, general clay brick for load-bearing structure, relatively thick, single shape; shale brick shapes, shapes with holes, in non bearing structure.
