Until Latin you have to leave to find the etymological origin of the term stone. Specifically, it must be stated that it derives from the word "petreus", which, in turn, emanates from the Greek "petreos", which can be translated as "rock".
This adjective refers to what is constituted or covered by rocks or stones . You can also name what looks rocky.
For example: “This stone monument is one of the most important of the pre-Hispanic era”, “Local people tend to live in stone houses as they manage to resist the inclement weather”, “The car behaved very well on the stony ground and we were able to complete the journey without inconvenience”.
It should be noted that it is known as stone to a very hard mineral compound, which is usually obtained from a type of exploitation called quarry. The most important characteristic of the stones is that they manage to keep their properties unchanged despite the passage of weather . Therefore, buildings and stone creations stand out for their durability.
In the field of geology , the hardest and cohesion stones are called rock . It is usual, however, that both concepts (stone and rock) are used as synonyms.
The stone materials they are those that come from the stones and that can be found either in a natural state or processed at an industrial level. Cement, granite and marble are some of the most popular stone materials.
It is important to know that these rock materials can be classified into four large groups:
-Depending on their nature, they can be metamorphic, sedimentary and igneous.
- Based on their origin, they can be divided into artificial, synthetic and natural.
- Starting from their size, they can be classified as filler, coarse aggregate and fine aggregate.
-Depending on their adhesiveness, they can be basic or acidic.
Stone, on the other hand, can be used in symbolic sense to qualify the person what's wrong with it poor gestures or what not moved by anything : "He is an actor who, even in the most dramatic scenes, remains stony", "His stone face was not modified despite the insults of the protesters".
In the same way, there is also what is known as a stone gaze. This term is used to indicate that a person who is looking at another in such a way that it seems that he is not human but a stone, because he does not show any kind of sensitivity or humanity.
Within fiction there is a stone character. We are referring to La Roca, one of the superheroes of the group “The Fantastic 4”, of the Marvel universe, which is called that because its appearance is precisely made of stone.
Also, do not forget that in Mexico, specifically in La Camelina, there is a company that responds to the name of Pétreo. It is dedicated exclusively to what is the commercialization of natural stone. Hence, it offers its customers the opportunity to acquire everything from marble to granites through blackboards or quarries.
