Music bell tin from China tells you that a good tin pot will "automatically" turn into a pile of powder. This "disease" of tin can also be transmitted to other "healthy" tin objects, which is called "tin disease". Music bell tin from China tells you that the cause of the tin plague is due to the change of the tin crystal lattice: at room temperature, tin has a tetragonal crystal structure, called white tin.

Music bell tin from China tells you that when you bend a tin bar, you can often hear a crackling sound, which is because the white tin crystals of the tetragonal system rub against each other when bending, making a sound. Below minus 13.2°C, white tin transforms into an amorphous gray tin. As a result, the lumps of tin turned into a mass of powder.
Music bell tin from China tells you that because tin is afraid of the cold, you should pay special attention not to let the tinware get cold in winter. There are many ironwares that are often welded with tin, and they cannot be frozen. In 1912, a foreign Antarctic expedition team went to Antarctica to explore. The gasoline barrels used were all soldered. In the ice and snow of Antarctica, the solder turned into the powdery gray tin, and the gasoline leaked out.
Music bell tin from China tells you that tin is not only afraid of cold, but also hot. Above 161°C, white tin turns into orthorhombic tin with the orthorhombic crystal structure. The orthorhombic tin is very brittle and breaks when it is knocked, and its ductility is very poor, so it is called "brittle tin". White tin, gray tin, and brittle tin are three allotropes of tin.
Through the above introduction and analysis of the Music bell tin from China introduce some knowledges about tin, hope it helps you.
