Before the invention of mechanical tools, all carving was done by hand with chisel and mace.
Stone carving is a controlled and systematic process. The correct use of the tools allows us to rough out big masses of material and to create the planes and simple shapes that contain the desired surfaces.
As the process goes on, the shapes get gradually more complex until we find the detail and reach the final surface.
This ordered progression through the shapes that contain and are contained get gradually more complex. This progression can be perceived in the finished work providing unity and personality to the design, thus allowing us to see the process we have followed.
HORIZONTAL PLANE
In order to Create a plane we must draw the intersection lines of the intended plane with the faces of the stone block. This operation will allow us to decide the material to be eliminated.
After setting the pitching tool on the block, a little bit above the line we can remove a lot of the excess material we must remove by hitting the block with the mallet.
Next, always starting from a corner and chiselling from the outside and towards the inside, we make the grooves as close as possible to the line without ever exceeding it.
We lift the chisel after each blow and we keep going so as to remove the excess material.
The grooves clearly show the material we must remove with the point chisel. Gradually, with this tool, we get closer to the desired surface without ever exceeding it.
We keep on hitting the stone with the tool and lifting it after each blow, trying not to stab it in the block stone constantly removing the excess stone from it.
During all this process we need a scale and a square in order to check the process.
We eliminate the irregularities left by the pointer with the tooth chisel and get as close as possible to the desired plane.
We may use the chisel to get a finer texture this time by tilting and pressing the tool against the surface less while hitting it with the mallet..
Chamfer or slanted plane
We may begin the carving of a chamfer or bevel using the pitching tool if the amount of material allows it,
Next we keep on using the chisel getting closer to the lanes of the chamfer. It must be done little by little until the chisel finds the desired inclination that we can perceive on the lines of the drawing.
Using the point chisel we remove excess material of the “islands” between the lanes.
During all this process we use a scale for checking out the measurements.
Using the tooth chisel we get as close as possible to the desired plane by smoothing the rough texture left by the point chisel.
We may look for a smoother finish using the chisel which will eliminate the traces or rough texture of the tooth chisel..
CONCAVE CURVE, CHANEL OR GROOVE
We start using the flat chisel in order to rough out the curve.
we gradually look for the lanes trying to find the inclination of the plane contained in the curve.
In order to remove the excess stone contained in the concave curve, we must first do it on the central section, this way the excess stone can be easily removed.
As we continue this process with the bullnose chisel, we keep looking for the final curve.
It is important to start this process from the beginning and constantly look for the tread or hump that will indicate the amount of material we must remove as we move forward. .
For this purpose, we can make a template that will help us to check the necessary

Maestros...que excelente enseñanza....tanto las explicaciones como la presentación paso a paso, el nombre de cada herramienta....muy didáctico...ahora ya comprendo por qué para aprender uno debe estar hombro a hombro con los maestros...mientras uds explicaban, yo acá con mis herramientas y un mazo de una libra....solo que demore, porque la roca era una piedra de río....muy dura por cierto....pero a mi parecer pase el examen de admisión, para seguir haciendo esculturas de piedra....de corazón les deseo, abundancia, prosperidad, salud, armonía, amor, alegría para uds y sus familias....hare krishna

Hola maestro. Que tal? Se puede hacer la Escultura en piedra totalmente en herramientas manuales, incluso en El lijado o cepillado? Para que no bote polvo daninos Al pulmon. O hay etapas q si requiere herramientas eléctricas? Gracias y felicitaciones por El trabajo! Me gustaria estudiar allá con ustedes
