The craft of stonemasonry has existed since the dawn of civilization - creating buildings, structures, and sculpture using stone from the earth. These materials have been used to construct many of the long-lasting, ancient monuments, artifacts, cathedrals, and cities in a wide variety of cultures. Famous products of stonemasonry include the Taj Mahal, Cusco's Incan Wall, Easter Island's statues, the Egyptian Pyramids, Angkor Wat, Borobudur, Tihuanaco, Tenochtitlan the Iranian Persepolis, the Greek Parthenon, Stonehenge, and Chartres Cathedral. Stonemasonry is the craft of shaping rough pieces of rock into accurate
geometrical shapes, mostly simple, but some of considerable complexity, and then arranging the resulting stones, often together
with mortar, to form structures. The modern stonemason undergoes comprehensive
training, both in the classroom and in the working environment. Hands-on skill is complimented by intimate knowledge of each
stone type, its application and best uses, and how to work and fix each stone in place. The mason may be skilled and competent
to carry out one or all of the various branches of stonemasonry. In some areas the trend is towards specialization, in other
areas towards adaptability. Stonemasonry is the craft of shaping rough pieces of rock into

areas towards adaptability. Stonemasons use all types of natural stone: igneous, metamorphic and sedimentary; while some also use artificial stone as well. Granite is one of the hardest stones, and requires such different techniques to sedimentary stones that it
is virtually a separate trade. With great persistence, simple mouldings can and have been carved into granite, for example
in many Cornish churches and the city of Aberdeen. Generally, however, it is used for purposes that require its strength and durability, such as kerbstones,
countertops, flooring, and breakwaters. Igneous stone ranges from very soft rocks such as pumice and scoria to somewhat harder rocks such as tuff and hard rocks such as obsidian, granite and basalt. Marble has traditionally been used for carving statues, and for facing many Byzantine and Renaissance Italian
buildings. The traditional home of the marble industry is the area around Carrara in Italy, from where a bright white marble is extracted in vast quantities. Slate is a popular choice of stone for memorials and inscriptions, as its fine grain and hardness means it
leaves details very sharp. Meanwhile, its tendency to split into thin plates has made it a popular roofing material. Many of the world's most
famous buildings have been built of sedimentary stone, from Durham Cathedral to St Peter's in Rome. There are two main types of sedimentary stone used in masonry work, limestones and sandstones. Examples of limestones include Bath and Portland stone. Yorkstone and Sydney sandstone are well-known sandstones. Types of stonemasonry are: Traditionally
medieval stonemasons served a seven-year apprenticeship. A similar system still operates today. A modern apprenticeship
lasts four years. This combines on-site learning through personal experience, the experience of the tradesmen and college
work where apprentices are given an overall experience of the building, hewing and theory work involved in masonry. In some
areas colleges offer courses which teach not only the manual skills but also related fields such as drafting and blueprint
reading or construction conservationism. Electronic Stonemasonry training resources enhance traditional delivery techniques.[1] Hands-on workshops are a good way to learn about stonemasonry also.[2] Those wishing to become stonemasons should have little problem working at heights, possess reasonable hand-eye co-ordination,
be moderately physically fit, and have basic mathematical ability. Most of these things can be developed while learning. Stonemasons use a wide variety
of tools to handle and shape stone blocks (ashlar) and slabs into finished articles. The basic tools for shaping the stone are a mallet, chisels, and a metal straight edge. With these one can make a flat surface - the basis of all stone masonry. Chisels
come in a variety of sizes and shapes, dependent upon the function for which they are being used. There are different chisels
for different materials and sizes of material being worked, for removing large amounts of material and for putting a fine
finish on the stone. Mixing mortar is normally done today with mortar mixers which usually
use a rotating drum or rotating paddles to mix the mortar. The masonry trowel is used for the application of the mortar between and around the stones as they are set into place.
Filling in the gaps (joints) with mortar is referred to as pointing. Pointing in smaller joints can be accomplished using
tuck pointers, pointing trowels, and margin trowels, among other tools. At least one tool bears the name of the tradesmen
that use it, and that is the Stonemason's hammer. This hammer can be used in place of a chisel in certain circumstances. The hammer can also be used
to make shims and chinks while holding a small stone in one hand and striking it with the hammer. Stonemasons
use a Lewis together with a crane or winch to hoist building stones into place. Today power tools
such as compressed-air chisels, abrasive spinners and angle grinders are much used: these save time and money, but are hazardous and require just as much skill as the hand
tools that they augment. But many of the basic tools of stonemasonry have remained virtually the same throughout vast amounts
of time, even thousands of years. Stonemasonry is one of the earliest trades in civilisation's history. During the time of the Neolithic Revolution and domestication of animals, people learned how to use fire to create quicklime, plasters, and mortars. They used these to fashion homes for themselves with mud, straw, or stone, and masonry
was born. The Ancients heavily relied on the stonemason to build the most impressive and
long lasting monuments to their civilizations. The Egyptians built their pyramids, the civilizations of Central American had their step pyramids, the Persians their palaces, the Greeks their temples, and the Romans their public works and wonders (See Roman Architecture). Among the famous ancient stonemasons is Sophroniscus, the father of Socrates, who was a stone-cutter. Castle building was an entire industry
for the medieval stonemasons. When the Western Roman Empire fell, building in dressed stone decreased in much of Western Europe, and there was a resulting increase in timber-based construction. Stone work experienced a resurgence
in the 9th and 10th centuries in Europe, and by the 12th century religious fervour resulted in the construction of thousands
of impressive churches and cathedrals in stone across Western Europe. Medieval stonemasons' skills were in high demand, and members of the guild, gave rise to three classes of stonemasons: apprentices, journeymen, and master masons. Apprentices were indentured to their masters as the price for their training, journeymen had a higher
level of skill and could go on journeys to assist their masters, and master masons were considered freemen who could travel
as they wished to work on the projects of the patrons. During the Renaissance, the stonemason's guild admitted members who were not stonemasons, and eventually evolved into the
Society of Freemasonry; fraternal groups which observe the traditional culture of stonemasons, but are not typically involved
in modern construction projects. A medieval stonemason would often carve a personal symbol onto their block to differentiate their work from that of other stonemasons. This also provided a simple
‘quality assurance’ system. The Renaissance saw stonemasonry return to the
prominence and sophistication of the Classical age. The rise of the Humanist philosophy gave people the ambition to create marvelous works of art. The centre stage for the Renaissance
would prove to be Italy, where city-states such as Florence erected great structures, including the Cathedral of Santa Maria del Fiore, the Fountain of Neptune, and the Laurentian Library which was planned and built by Michelangelo Buonarroti, a famous stonemason of the Renaissance. When Europeans settled
the Americas, they brought the stonemasonry techniques of their respective homelands with them. Settlers used what materials
were available, and in some areas stone was the material of choice. In the first waves, building mimicked that of Europe,
to eventually be replaced by unique architecture later on. In the 20th century, stonemasonry
saw its most radical changes in the way the work is accomplished. Prior to the first half of the century, most heavy work
was executed by draft animals or human muscle power. With the arrival of the internal combustion engine, many of these hard aspects of the trade have been made simpler and easier. Cranes and forklifts have made moving and laying heavy stones relatively easy for the stonemasons. Motor powered mortar
mixers have saved much in time and energy as well. Compressed-air powered tools have made working of stone less time-intensive. Petrol and electric powered abrasive saws can cut through stone much faster and with more precision than chiseling alone. Carbide-tipped chisels can stand up to much more abuse than the steel and iron chisels made by blacksmiths of old. A stone mason is a person who is skilled in the art of stone carving, stone laying and stone fitting. This is a specialised profession and requires a high degree of sculpting skills and expertise. A stone mason is generally found working on projects involving the construction of artistic structures and monuments. Stoneworking is the skill of working with stones and comprises of stone carving, stone laying and stone fitting. Yellow™ contains a comprehensive list of stone masons and stoneworkers across Australia. A stone mason usually works in a workshop or on the client’s construction site. A stone mason is often referred to as a banker mason when the job involves carving and shaping stones according to specific design instructions. The stone mason also uses electric powered tools to give the stone structure a textured or polished finish. A stone mason is called a fixer when the job involves building stone walls by using mortar and special fixings. If you are a caretaker of an old heritage building and you want to conduct repairs, it is recommended that you always hire a stone mason. Like a sculptor, a stone mason can also carve stone statues and construct memorial headstones. Sandstone (sometimes known as arenite) is a sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust. Like sand, sandstone may be any color, but the most common colors are tan, brown, yellow, red, gray
and pink, white. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Some sandstones are resistant to weathering, yet are easy to work. This makes sandstone a common building and paving material. However, some that have been used in the past, such as the Collyhurst sandstone used in North West England, have been found less resistant, necessitating repair and replacement in older buildings.[1] Because of the hardness of the individual grains, uniformity of grain size and friability of their structure, some types of sandstone are excellent materials from which to make grindstones, for sharpening blades and other implements. Non-friable sandstone can be used to make grindstones
for grinding grain, e.g., gritstone. Rock formations that are primarily composed of sandstone usually
allow percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Fine-grained aquifers, such as sandstones, are more apt to filter out pollutants from the surface
than are rocks with cracks and crevices, such as limestone or other rocks fractured by seismic activity. Sandstones are clastic in origin (as opposed to either organic, like chalk and coal, or chemical, like gypsum and jasper).[2] They are formed from cemented grains that may either be fragments of a pre-existing rock or be mono-minerallic crystals. The cements binding these grains together are typically calcite, clays and silica. Grain sizes in sands are defined (in geology) within the range of 0.0625 mm to 2 mm (0.002-0.079 inches).
Clays and sediments with smaller grain sizes not visible with the naked eye, including siltstones and shales, are typically called argillaceous sediments; rocks with larger grain sizes, including breccias and conglomerates are termed rudaceous sediments. The formation of sandstone
involves two principal stages. First, a layer or layers of sand accumulates as the result of sedimentation, either from water (as in a river, lake, or sea) or from air (as in a desert). Typically, sedimentation
occurs by the sand settling out from suspension; i.e., ceasing to be rolled or bounced along the bottom of a body of water
(e.g., seas or rivers) or ground surface (e.g., in a desert or erg). Finally, once it has accumulated, the sand becomes sandstone when it is compacted by pressure of overlying deposits and cemented by the precipitation of minerals within the pore spaces
between sand grains. The most common cementing materials are silica and calcium carbonate, which are often derived either from dissolution or from alteration of the sand after it was buried.
Colors will usually be tan or yellow (from a blend of the clear quartz with the dark amber feldspar content of the sand).
A predominant additional colorant in the southwestern United States is iron oxide, which imparts reddish tints ranging from pink to dark red (terracotta), with additional manganese imparting a purplish hue. Red sandstones are also seen in the Southwest and West of Britain, as well as central Europe and Mongolia. The regularity of the latter favors use as a source for masonry, either as a primary building material or as a facing stone, over other construction. The environment where it is deposited is crucial in determining the characteristics of the resulting sandstone,
which, in finer detail, include its grain size, sorting and composition and, in more general detail,
include the rock geometry and sedimentary structures. Principal environments of deposition may be split between terrestrial and marine, as illustrated by the following broad groupings: All sandstone are composed of the same general minerals. These minerals make up the framework components of the sandstones. Such components are quartz, feldspars, and lithic fragments. Matrix may also be present in the interstitial spaces between the framework grains.[6] Below is a list of several major groups of sandstones. These groups are divided based on mineralogy and texture. Even though sandstones have very simple compositions which are based on framework grains, geologists have not been able to agree on a specific, right way, to classify sandstones.[6] Sandstone classifications are typically done by point-counting a thin section using a method like the Gazzi-Dickinson Method. The composition of a sandstone can have important information regarding the genesis of the sediment when use with a triangle Quartz, Feldspar, Lithic Fragment (QFL diagrams). Many geologist however do not agree on how to separate the triangle parts into the single components so that the framework grains can be plotted.[6]Therefore, there have been many published ways to classify sandstones, all of which are similar in their general format. Visual aids are diagrams that allow geologists to interpret different characteristics about a sandstone. The following QFL chart and the sandstone provenance model correspond with each other therefore, when the QFL chart is plotted those points can the be plotted on the sandstone provenance model. The stage of textural maturity chart illustrates the different stages that a sandstone goes through.
