Mercury – heavy liquid metal whose chemical element under symbol Hg is classified in VI periods of Mendeleyev's periodic system with atomic number 80.   Mercury’s metallic substance belongs to the first-row transition metals, dissolving many other metals inclusive gold and silver thus forming amalgam; Iron is the only metal that is non-dissolving by mercury metal therefore it is used as a packaging material for mercury.

Mercury is heavy and liquid at room temperature; its vapors are extremely poisonous, hence, mercury must be produced in strict accordance with the manufacturing standards and safety requirements.

Mercury is produced/purified to the grades R0, R1, R2, and R3.

The amount of the basic substance (pure mercury) and non-volatile residue do correspond to the indications of table 1.
