I have my stone marble and laboratory staff for more than 25 years and was a normal event for us, that visitors buy a piece of marble or stone, to try to cut rock. I have a weakness for all budding artists, so I never pay for the stone would have asked instead to return to their work, so I could see what was coming.
In all the years, no one ever is back!
Now I know that most people really decent return,Let me see your work, I did this lack of response to the fact that most of these novice carvers simply choose the wrong kind of material to begin with, and never really successful, the work done.
Most of hope I wanted to cut marble as we have seen over the years, and so despite my advice to try a softer stone, are controlled as not to be seen again with a nice piece of white Carrara or Italian Botticino Fiorito. (For me anyway!)
TheIt 's a fact that there is hard work especially marble and stone carving. If you start a soft and relatively easy to work sort of stone, and choosing the right tools, is easily discouraged and give up long before being able to take the necessary practical skills to the hardest stone, and marble processing must be developed .
This would builders choose the right kind of stone, I felt a sort of Mohs hardness of rock types, you createlikely to find in your local stone yards.
This is not a scientific level, is not only strength but also on the practical feasibility of the stone. I thought that working with hand tools, power tools.
The scale is numbered 1-10. 1 is the softest and 10 the hardest stone.
