Inlage

Inlage is a term used in German and in some technical English texts to describe an inserted piece of material that forms part of a larger object. The word derives from einlegen, meaning to lay in or insert, and denotes something laid into a base surface or structure.

Applications of inlage span several crafts and industries. In woodworking and cabinetry, an Inlage refers to a decorative or functional insert embedded into a surface, often created with contrasting materials such as different woods, metals, shells, or stones. Inlays are common in fine furniture, marquetry, and architectural details, where they define patterns, borders, or pictorial motifs and are typically smoothed and finished to blend with the surrounding material. In jewelry and metalwork, an Inlage may describe an inserted element that provides contrast or structural purpose within a piece.

In mechanical engineering and manufacturing, the term can describe inserts or liners used within assemblies to improve wear resistance, adjust fit, or repair worn sections. In dentistry and medicine, the standard English term is inlay (not Inlage), and the German word for the concept is usually inlay or Inlaywork in professional contexts; Inlage is uncommon in clinical terminology today.

Overall, Inlage denotes an insert or inlaid element that enhances appearance, function, or durability by being set into a base material. Synonyms include inlay, insert, and lining, depending on context.
