Summary edit
| Description |
English: Rock was excavated by cutting a shallow, circular track which would be filled with burnable material. When set on fire, the heat would crack the rock which was then removed to a certain depth, and the process repeated. Wedges were used to produce a similar
result; a wooden wedge hammered into the rock, when soaked with water, will expand with enough force to crack the rock. |
