I have compiled a list of sources for the elements that are available to the amateur chemist. Aluminium will be discussed here.
Aluminium is a very common, light, silvery gray metal. It requires much energy to extract from its ores and can be recycled economically. It is used in many structural applications. Aluminium compounds are used to purify water and deodorize.
In element form: Many objects, such as aluminium foil, are made of aluminium.
In compound form: Some deodorants have aluminium chloride or oxychloride in them. Emery is made of aluminium oxide.
Here is my sample of aluminium. It is a piece of aluminium foil that is crumpled.
