It is got out in very large blocks. Sometimes gunpowder is used to crack the rocks before the blocks can be got out. 2. Slate is very hard and brittle. It is used for many purposes. Houses are roofed with slates. Sometimes it is used for pavements. It can be made so smooth that we use it for writing upon. Slate-pencil is made from soft slate-stone.
