Definitions

  • the present invention is the result of. these experiments. It has been found that salt solutions of metals, which incline to easily form double salts and which act upon metallic zinc are specially suited for the reliminary treatment.
  • the method of preparing zinc plates has proved to be suitable for metallographic purposes.
  • this preliminary preparing for metallographic purposes shortens the workmg time and presents further the advantage of increasing by the preliminary preparation of the durability of the metallographic plate.
