What is Stone Masonry?
Thursday, December 2nd, 2010Let’s kick things off with a look at just exactly what stone masonry is and how it has evolved through the centuries to the modern equivalent that is around today.
Stone masonry is by definition the craft of shaping or forming rough chunks of rock (stone) into accurate, well formed geometrical shapes and then arranging the formed and shaped stones, most often along with a cement based or other adhesive mortar, to create and form buildings or structures. These shapes are mostly simple in form, although you can get some that are of considerable complexity.
The process is carried out by a number of skilled artisans. This begins with the quarrymen who quarry and then split the base rock, and then extract rough hewn stone blocks from the ground. The next stage is carried out by sawyers, who cut the large blocks into smaller cubes to the required size as per order with large, diamond-tipped saws.
The next stage is carried out by banker masons in the workshop. These masons specialize in carving the rough stones into the smooth and accurate geometrical shapes that are required by the building’s design. These masons are capable of producing just about anything from stones including simple chamfers for tracery windows, right up to highly detailed moldings that comprise such things as classical architectural building. The mason working a stone from a basic sawn block ensures the stone is correctly bedded, so the finished work will sit in the finished building with the same orientation that it had when it was quarried from the ground.
More specialized forms of masonry include the work of carvers, who create more of an art form, using their artistic skill and ability to carve rough stone into incredibly detailed shapes and reliefs, including figures, animals, plants and foliage or more abstract designs.
Where the erection of buildings requires stone masons to be on-site, there are what is known as fixer masons. These masons specialize in fixing stones onto the buildings as they are erected. They use lifting tackle, machinery as well as traditional lime mortars and grouts to create the finished effect. Depending upon the style of building, modern cements, or even mastic and epoxy resins may be used. This is often seen on specialist building styles such as stone cladding.
Lastly, memorial masons or sometimes known as monumental masons specialize in carving gravestones and engraving inscriptions such as epitaphs.
Stone masons undergo long and arduous training to acquire the necessary skills to be able to create the finished product as required by the builder as per the architect’s plans. Skills are learned by extensive practical training, as this is one trade that cannot be easily learned just from books and is a skill that has been taught and handed down from father to son for millenia.
