How phonographs records are made

How phonographs records are made, Popular Science 1947 – “THE silent black disk that makes noises when needled is chiefly shellac, lampblack and limestone.

For example, 50 percent of the wax-coated glass disks on which the music is recorded are rejected before reaching the cutting room. The accompanying pictures tell the story.” – Link.
