The melting pot

The melting pot is the pot where materials, usually metals, are heated to their melting temperature until they liquefy and blend together to form an alloy that have better properties of each original metal. Now, in order to obtain this, the right materials need to be chosen, usually metals, and metals with similar properties. Not every mix work, no matter how long you heat it. If you don't pick the right materials, they won't blend at all or originate a very poor alloy. Also the amount of each material is important. It's just not possible to mix any quantity of the right materials and obtain a good alloy. This is applicable also to societies. You cannot just mix any culture in any quantity and hope they will mix well generating a better society. Quality and quantity do matter. Our politicians that want to throw us all in the melting pot should study some chemistry before taking their decisions.
