In the arts, a medium is a material used by an artist or designer to create a work.
In the art and science of architecture, the design and construction of buildings and interiors, infrastructure and other physical structures are created. It can involve multiple disciplines of brickwork, carpentry, engineering, stonemasonry and many other skills.
The art of carpentry and woodworking is by a skilled craftsperson or joiner, who designs and builds buildings, furniture and other objects.
In drawing, "media" refers to both the material that is manually applied and to the base onto which it is applied. The media applied can be many things but the method of application is a stick type object with a point (not a brush) that transfers particles of media to the base. The point of the stick can be as minute as it can be large.
The most commonly practiced form of drawing or sketching is with a pencil and paper, however the wide and varied use of materials applied can be graphite, fusain, pastel, and ink among other things. Bases can be paper, plaster, canvas, wood or basically anything that accepts the medium applied from the point of the stick.
