DRESSING OF STONES

Dressing of stone is the process of giving a proper size, shape and finish to stones obtained
from quarry. This is either done manually or mechanically.

Objectives of stone dressing

 To set the stones in a regular shape and appearance.


 To reduce the size of blocks to easily portable units. This is often done at the quarry
itself because of big blocks may become costly to convey.
 To obtain an appealing finish. Stones often come in rough and rugged forms for use in
building construction in walls and exteriors; they have to be given aesthetically
appealing finish.

METHODS OF STONE DRESSING
As before dressing of stones can be done manually and mechanically.
Mechanically, special saw fitted machines can cut stone slabs, blocks and any other
shape from rough rocks. These are called rock cutters. The grinding and polishing
machines are fitted with wheels or discs with abrasives capable enough to give and
final finish to any desired degree even on the hardest stones.
Traditional methods of dressing stones
 Pitched dressing, in this method only the edges of a stone are made level with
the skillful use of hammers.
 Hammer dressing, it is dressing in which edges as well as faces are reduced to
an even regular surface.
 Chisel drafting. In this method, straight grooves are made with the help of a
chisel at all the four edges.
