It's hard because of the chemicals that are inside of it. Though aluminum foil is not so hard it's still made out of aluminum.

Does hard anodized alum conduct electricity?

Hard anodized aluminum is an insulating material and does not conduct electricity effectively. The anodization process creates a thick oxide layer on the aluminum surface, which acts as an electrical insulator. However, the underlying aluminum itself is a good conductor, but it is typically not exposed in hard anodized products.


Can you dig pure aluminium out of the ground?

Many people "mine" old dumpsites for pure metals and other materials. There is, however, no source of pure aluminum in nature. Aluminum ore (Bauxite) is composed of aluminum oxids and hydroxides


Circulon - reactive or nonreactive?

Manufacturers found that aluminum can be anodized to make it stronger, slicker, more durable, and non-reactive with foods. This applies to many types of cookware, including Circulon and Calphalon.Calphalon, a maker of anodized aluminum cookware explains it this way:"Hard-anodization is an electro-chemical process that hardens aluminum. (Hard-Anodized aluminum is 30% harder than stainless steel.) During hard-anodization, aluminum is submerged in an acid bath, then subjected to electrical charges. The result is a chemical reaction wherein the surface of the aluminum combines with oxygen to become aluminum oxide. This reaction is also known as oxidation, a process which occurs spontaneously in nature. Hard-anodization is actually controlled, accelerated oxidation.


How long will aluminum last if you continue mining and using it at current rates?

The known reserves of Bauxite (the ore from which aluminum is mined) are expected to last another two hundred years or so if we continue to mine it at current rates.


How do you get bauxite?

Bauxite is primarily mined through open-pit or strip mining techniques. After being extracted, the bauxite ore is processed to refine the aluminum oxide compound found within it, which can then be used to produce aluminum through the electrolysis process.

You get the hard hat in the Cave Mine (the room on the left of the hidden lake and on the up of the Mine, where you drill for coins). Walk to the hard hat that you see and obtain the item.
