                       Hardstone carving

Hardstone carving is a general term in art history and archaeology for the artistic carving of predominantly semi-precious stones (but also of gemstones), such as jade, rock crystal (clear quartz), agate, onyx, jasper, serpentine, or carnelian, and for an object made in this way. Normally the objects are small, and the category overlaps with both jewellery and sculpture. Hardstone carving is sometimes referred to by the Italian term pietre dure; however, pietre dura (with an "a") is the common term used for stone inlay work, which causes some confusion.

From the Neolithic period until about the 19th century such objects were among the most highly prized in a wide variety of cultures, often attributed special powers or religious significance, but today coverage in non-specialist art history tends to be relegated to a catch-all decorative arts or "minor arts" category. The types of objects carved have included those with ritual or religious purposes,engraved gems as signet rings and other kinds of seal, handles, belt hooks and similar items, vessels and purely decorative objects.

                         

                        Bone carving

Bone carving is the act of creating art forms by carving into animal bones and often includes the carving of antlers and horns. It can result in the ornamentation of a bone, or the creation of a figure. It has been practiced by a variety of world cultures, sometimes as a cheaper, and recently a legal, substitute for ivory carving. It was important in prehistoric art, with notable figures like the Swimming Reindeer (antler), and many of the Venus figurines. The Anglo-Saxon Franks Casket is a bone casket imitating earlier ivory ones.

Bone was also used by artists and craftsmen to try out their designs, especially by metalworkers. Such pieces are known as "trial-pieces".

                      

                          Metalworking

Metalworking is the process of working with metals to create individual parts, assemblies, or large-scale structures. The term covers a wide range of work from large ships and bridges to precise engine parts and delicate jewelry. It therefore includes a correspondingly wide range of skills, processes, and tools.

Metalworking is a science, art, hobby, industry and trade. Its historical roots span cultures, civilizations, and millennia. Metalworking has evolved from the discovery of smelting various ores, producing malleable and ductile metal useful for tools and adornments. Modern metalworking processes, though diverse and specialized, can be categorized as forming, cutting, or joining processes. Today's machine shop includes a number of machine tools capable of creating a precise, useful workpiece.
