The concept of boulder is used to name a piece of stone that has not been carved . Boulders, therefore, are pieces of rock that were not worked by man to modify their shape or state.
For example: “A rock broke my car tire when I was driving through a mountainous area two days ago,” “According to witnesses, the boy tripped over a rock and ended up falling off the cliff,” “The sea lion came out of the sea .” and he rested several hours on a rock.”
It is important to keep in mind that there are other meanings of rock. The term also refers to a large gemstone : “Rumors indicate that the rock that the singer gave to his fiancée is worth more than half a million dollars,” “Look at the rock in that pendant! It must cost a fortune” , “In its new exhibition, the museum exhibits a rock with unique characteristics” .
The process that allows us to turn a boulder into a stone requires the fusion of various techniques and tools, without leaving aside a skill that is acquired little by little with experience. The manufacture of articles with sculpted stone is one of the oldest activities that exist, and throughout history different working methods have been developed to carve, cut, drill, polish, glue and clean the stone .
The first step, even before getting the rock that we want to transform, is to prepare the design on paper. It is important to have clear objectives to minimize the chances of drastic changes in the middle of the process. Just as in any other creative discipline that requires different manual skills, it is recommended to start with simple motifs such as fundamental geometric figures, since there will always be time to embark on more complex projects.
Regarding the state of the stone, to begin with it is especially appropriate to choose a healthy one, that is, without cracks, fissures, flaws in its structure or betas that could lead to accidental breaks during carving. To detect these defects it is not enough to observe the piece, but there are certain procedures that allow us to ensure its good condition; For example, submerge it in water so that the cracks are seen more clearly or hit its base with a hammer or chisel to check that it does not sound hollow, which would reveal the presence of an anomaly inside.
Another important point to take into account when choosing a stone to work on is the size: it must be much larger than the piece we want to obtain, since between carving, cutting and polishing we will reduce it considerably. . Furthermore, once we have made the design on paper and we have the stone, we must draw on it with a wax pencil, which is why a generous margin is needed to capture it correctly before starting to modify the surface.
The notion of a boulder, on the other hand, is used symbolically to refer to a difficulty : “An injury to the left ankle became a boulder in the striker's career, until a surgical intervention allowed him to regain his normal mobility,” “ I stumbled upon the same obstacle several times: my boss's lies,” “Although the lack of official information was a obstacle, we managed to move forward with the investigation until we discovered the truth.”
