=STONE=

Stone is an element that comes from earth, I believe them to be pieces of larger rocks that can be used by the people for a bunch of different purposes
 * What are stones?**

I’m not quite sure, I think there are many types of stones as there are many types of soil. There can be really hard heavy stones from the mountains or soft sand kind of stones from the beach.
 * How many kinds of stones do you know?**

They can be shapeable, fire resistant, natural weather insulator, very resistant, non permeable.
 * What characteristics do stones have?**

Well they are used because all the characteristics we already mentioned, they can be used in the construction of resistant safe structures. media type="file" key="Stones.mp3" Stones are commonly used in constructions because of __they__ effective bonding properties which barely requires mortar **unlike brick structures**. Also, stones can be __cutted__ in blocks and arranged with an entablature or broke and bonded with mortar which we know as rubble. But working with stones have also advantages and disadvantages, __for one side__ they can be used naturally, they can be very easily adapted for an sculptural treatment and they have a remarkable durability **and strength that makes them perfect for monolithic constructions, there are still stone constructions from centuries ago**. __For the other side__ they can be very expensive and hard to transport, unstable and somehow weak in tension, **for example, shapes like arches need more support when made from stone than any other material.** __This__ both aspects have to come into consideration when working with stones.
