In which type of dressing are only the edges of a stone block levelled with the help of a hammer?

Explanation:

Pitched dressing 

• In Pitched dressing, only the edges of a stone block are made level with the help of a hammer.
• The superfluous mass on the face is generally left intact.

 Additional InformationHammer dressing ​

• It is that type of dressing in which large raised portions of the stones are broken off, and the stone is shaped somewhat flat but rough due to hammer marks.
• A hammered-dressed stone has no sharp and irregular corners and has a comparatively even surface to fit well in the masonry.
• These stone blocks are squared, and the bed and vertical sides are dressed to a distance of 8 to 10 cm from the face. This is done to enable the stone to have proper joints.
• This work is done by using the waller’s hammer. The obtained stones are termed as hammer faced, quarry-faced, or rustic faced.

​Chisel drafting 

• In this method, drafts or grooves are made with the help of a chisel at all the four edges, and any excessive stone from the center is then removed.
• Any superfluous stone from the center is then removed. Chisel drafted stones are specially used in plinths and corners of the buildings.

​Rough tooling 

• The edges are first squared by using a chisel and hammer.
• Then a series of grooves of variable width (4-5 cm), more or less parallel to the tool marks, are developed over the surface of the stone.
