Indium is a soft, malleable metal with a brilliant lustre. The name indium originates from the indigo blue it shows in a spectroscope. Indium has a low melting point for metals and above its melting point it ignites burning with a violet flame.

Is bismuth a metal?

Bismuth is a white, crystalline, brittle metal with a pinkish tinge. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal except for mercury.

Can you touch indium?

Indium forms an alloy with gallium that is liquid at room temperature, and is fairly non-toxic. This would be a great substitute for mercury, except it sticks to everything and stains hands, which means you can't really touch it either.
