In bookbinding, inlays and onlays are pieces of leather adhered to the cover of a book, usually differing in color, grain, or both from the main covering leather. While they are complementary techniques, and may appear similar in their final forms, they are distinct in how they are constructed.
Leather inlays, which are similar in form to inlays in woodworking, are shaped pieces of leather the same thickness as the covering leather on a book. A piece of leather the same shape, size, and thickness as the inlay is removed from the covering leather, and the inlay is placed into the resulting space. The edge of the inlay can be tooled, in which case the edge of the inlay is beveled, with the skin side of the leather slightly larger than the flesh side. This gives a smooth, well-supported surface for the impressions of the finishing tools.
Often mistaken for inlays, onlays are thin pieces of leather (often less than 0.2 mm) which are adhered over the covering leather on a book. Because of their thinness, onlays are not noticeably raised from the surface of the covering leather. Onlays are adhered to the covering leather with paste or PVA, and their edges are usually, though not universally, tooled over in order to hide any minor irregularities. They are often added to the spine of a book, containing the title and author's name.
Leather is a durable and flexible material created by tanning animal rawhide and skins. The most common raw material is cattle hide. It can be produced at manufacturing scales ranging from artisan to modern industrial scale.
A chisel is a tool with a characteristically shaped cutting edge of blade on its end, for carving or cutting a hard material such as wood, stone, or metal by hand, struck with a mallet, or mechanical power. The handle and blade of some types of chisel are made of metal or of wood with a sharp edge in it.
Gilding is any decorative technique for applying a very thin coating of gold to solid surfaces such as metal, wood, porcelain, or stone. A gilded object is also described as "gilt". Where metal is gilded, it was traditionally silver in the West, to make silver-gilt objects, but gilt-bronze is commonly used in China, and also called ormolu if it is Western. Methods of gilding include hand application and gluing, typically of gold leaf, chemical gilding, and electroplating, the last also called gold plating. Parcel-gilt objects are only gilded over part of their surfaces. This may mean that all of the inside, and none of the outside, of a chalice or similar vessel is gilded, or that patterns or images are made up by using a combination of gilt and ungilted areas.
A pointe shoe is a type of shoe worn by ballet dancers when performing pointe work. Pointe shoes were conceived in response to the desire for dancers to appear weightless and sylph-like and have evolved to enable dancers to dance en pointe for extended periods of time. They are manufactured in a variety of colors, most commonly in shades of light pink.
A hand plane is a tool for shaping wood using muscle power to force the cutting blade over the wood surface. Some rotary power planers are motorized power tools used for the same types of larger tasks, but are unsuitable for fine scale planing where a miniature hand plane is used.
A file is a tool used to remove fine amounts of material from a workpiece. It is common in woodworking, metalworking, and other similar trade and hobby tasks. Most are hand tools, made of a case hardened steel bar of rectangular, square, triangular, or round cross-section, with one or more surfaces cut with sharp, generally parallel teeth. A narrow, pointed tang is common at one end, to which a handle may be fitted.
Sheet metal is metal formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Countless everyday objects are fabricated from sheet metal. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate steel or "structural steel."
A kitchen knife is any knife that is intended to be used in food preparation. While much of this work can be accomplished with a few general-purpose knives – notably a large chef's knife, a tough cleaver, and a small paring knife – there are also many specialized knives that are designed for specific tasks. Kitchen knives can be made from several different materials.
In dentistry, inlays and onlays are a form of indirect restoration. This means they are made outside of the mouth as a single, solid piece, that fits the specific size and shape of the cavity. The restoration is then cemented in place in the mouth. This is an alternative to a direct restoration, made out of composite, amalgam or glass ionomer, that is built up within the mouth.
Leather carving is the process of giving a three-dimensional appearance to leather craft objects or works of art by cutting and stamping the surface.
Metalworking hand tools are hand tools that are used in the metalworking field. Hand tools are powered solely by the operator.
A treasure binding or jewelled bookbinding is a luxurious book cover using metalwork in gold or silver, jewels or ivory, perhaps in addition to more usual bookbinding material for book-covers such as leather, velvet, or other cloth. The actual bookbinding technique is the same as for other medieval books, with the folios, normally of vellum, stitched together and bound to wooden cover boards. The metal furnishings of the treasure binding are then fixed, normally by tacks, onto these boards. Treasure bindings appear to have existed from at least Late Antiquity, though there are no surviving examples from so early, and Early Medieval examples are very rare. They were less used by the end of the Middle Ages, but a few continued to be produced in the West even up to the present day, and many more in areas where Eastern Orthodoxy predominated. The bindings were mainly used on grand illuminated manuscripts, especially gospel books designed for the altar and use in church services, rather than study in the library.
Bindery refers to a studio, workshop or factory where sheets of (usually) paper are fastened together to make books, but also where gold and other decorative elements are added to the exterior of books, where boxes or slipcases for books are made and where the restoration of books is carried out.
This glossary of woodworking lists a number of specialized terms and concepts used in woodworking, carpentry, and related disciplines.
Fixed prosthodontics is the area of prosthodontics focused on permanently attached (fixed) dental prostheses. Such dental restorations, also referred to as indirect restorations, include crowns, bridges, inlays, onlays, and veneers. Prosthodontists are specialist dentists who have undertaken training recognized by academic institutions in this field. Fixed prosthodontics can be used to restore single or multiple teeth, spanning areas where teeth have been lost. In general, the main advantages of fixed prosthodontics when compared to direct restorations is the superior strength when used in large restorations, and the ability to create an aesthetic looking tooth. As with any dental restoration, principles used to determine the appropriate restoration involves consideration of the materials to be used, extent of tooth destruction, orientation and location of tooth, and condition of neighboring teeth.
Coptic binding or Coptic sewing comprises methods of bookbinding employed by early Christians in Egypt, the Copts, and used from as early as the 2nd century AD to the 11th century. The term is also used to describe modern bindings sewn in the same style.
In bookbinding, finishing refers to the process of decorating the outside of a book, including the lettering of the spine and covers, any additional tooling, and any inlays and onlays. Finishing can also include the gilding or other decoration of the edges of the book's pages.
Limp binding is a bookbinding method in which the book has flexible cloth, leather, vellum, or (rarely) paper sides. When the sides of the book are made of vellum, the bookbinding method is also known as limp vellum.
Bookbinding is the process of physically assembling a book of codex format from an ordered stack of paper sheets that are folded together into sections or sometimes left as a stack of individual sheets. The stack is then bound together along one edge by either sewing with thread through the folds or by a layer of flexible adhesive. Alternative methods of binding that are cheaper but less permanent include loose-leaf rings, individual screw posts or binding posts, twin loop spine coils, plastic spiral coils, and plastic spine combs. For protection, the bound stack is either wrapped in a flexible cover or attached to stiff boards. Finally, an attractive cover is adhered to the boards, including identifying information and decoration. Book artists or specialists in book decoration can also greatly enhance a book's content by creating book-like objects with artistic merit of exceptional quality.
A welding joint is a point or edge where two or more pieces of metal or plastic are joined together. They are formed by welding two or more workpieces according to a particular geometry. There are five types of joints referred to by the American Welding Society: butt, corner, edge, lap, and tee. These configurations may have various configurations at the joint where actual welding can occur.
