Details on our liquid silver mercury

Details on our liquid silver mercury
The metallic or elemental mercury is a bright, silvery-white metal known as silvery mercury. Because of its silver color, this element is sometimes referred to as liquid silver or mercury, which means living silver. It is the only metallic element that retains its liquid state at ambient temperature.
Applications of our silver mercury include mercury switches, fluorescent tubes, liquid reflecting telescopes, mercury relays, batteries, thermometers, barometers and other devices, all of which use high levels of mercury. Buy liquid mercury from us at wholesale prices.
