Something stony is built with stone.
Pétreo is an adjective referring to that which is made up or covered by rocks or stones . You can also name what has a rocky appearance.
For example: “This stone monument is one of the most important from the pre-Hispanic era” , “Local residents usually live in stone houses since they are able to resist the inclement weather” , “The car behaved very well on the stone terrain and “We were able to complete the journey without any problems.”
You have to go to Latin to find the etymological origin of the term. Specifically, it must be stated that it derives from the word petreus , which, in turn, emanates from the Greek petreos , translatable as "rock" .
stone materials
It should be noted that a very hard mineral compound is known as a stone , which is generally obtained from a type of exploitation called a quarry. The most important characteristic of stones is that they manage to keep their properties unchanged despite the passage of time . For this reason, stone constructions and creations stand out for their durability.
In the field of geology , the hardest and most cohesive stones are called rocks . It is common, however, for both concepts (stone and rock) to be used synonymously.
Stone materials are those that come from stones and can be found either in their natural state or processed at an industrial level. Cement, granite and marble are some of the most popular stone materials.
There are different kinds of stone materials.
Classification according to type
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 or igneous .
- Based on their origin, they can be divided into artificial , synthetic or natural .
- Based on their size, they can be classified as filler , coarse aggregate or fine aggregate .
- Depending on their adhesiveness, they can be basic or acidic .
Symbolic use of the term stone
Stone, on the other hand, can be used in a symbolic sense to describe the person who has little gesture or who is not moved by anything : “He is an actor who, even in the most dramatic scenes, remains stone” , “His stone face “It was not modified despite the insults of the protesters.”
In the same way, there is also what is known as a stony look . This term is used to indicate that a person who is looking at another in such a way that it seems that they are not human but a stone, because they do not show any type of sensitivity or humanity.
More uses of the notion
Within fiction there is a famous stone character. We are referring to The Rock , one of the superheroes members of the group “The Fantastic Four” , from the Marvel universe, who is called that because his appearance is precisely made of stone.
Likewise, we must not forget that in Mexico , specifically in La Camelina , there is a company that goes by the name of Pétreo . It is dedicated exclusively to the marketing of natural stone. Hence, it offers its clients the opportunity to purchase everything from all types of marble to granite, including slate or quarries.
