Tin is built up from a crystal structure. This structure is cubic in shape and is called a tetragonal crystal system.In its pure form it is a fairly soft and bendy metal. When bending the metal you can hear the crystals breaking. This does not mean that tin is brittle, but that it has a certain elasticity.
Tin is a “white-coloured metal”, its colour lies between that of silver and aluminium and can sometimes even lean towards gold. By polishing tin highly, the tin gets a silver-white colour and shines just like silver. Pure tin is non-toxic and is not easily absorbed by the body. It is a metal that can come in contact with our body and food for a long time and it is resistant to most acids.
