How many ways are there to work with stone?
~~~~~~~~~~~
See #13, this thread
To those major methods for friable stone, add "Indirect percussion" (aka "punching")
Then add "pecking, grinding, and polishing", which are commonly used to shape granular, non-glass-like stone. (pipes, celts)
And, then, there are "brute force methods" such as "grooving, wedging and splitting") for quarrying tough, granular stone.
