Observation and experiments

1. First of all, carry on the preliminary measurement to the sample, measure the basic data such as shape, size, weight and so on.
2. Secondly, make an observation. The cross section of the sample has fluidity texture and the appearance shows silver-white metallic luster.
3. Then, cut off some slices of samples for small experiments.

• Indium has a certain irritation to the skin, so it is necessary to wear gloves to protect yourself during experiments.
• The texture is very soft and can be scratched with fingernails.
• When heated to about 150 °C, the indium slices begin to melt into a silver liquid.
• After taking it out, it oxidized slowly in the air, formed an oxide film on the surface, and gradually lost its metallic luster. When indium was put into the water, it sank to the bottom and oxidizes slowly.

4. Finally, disposal of waste samples and storage of remaining samples.

• The waste samples and the remaining samples were stored in two closed containers respectively.
• Send the waste samples to a approved treatment plant.
• Store the remaining samples in a cool and ventilated place to avoid direct sunlight.
