Mosaic

==Three techniques==
There are three main methods: the direct method, the indirect method and the double indirect method.

===Direct method===

The direct method of mosaic construction involves directly placing (gluing) the individual [[tessera]]e onto the supporting surface. This method is well suited to surfaces that have a three-dimensional quality, such as vases.  This was used for the historic European wall and ceiling mosaics, following [[underdrawing]]s of the main outlines on the wall below, which are often revealed again when the mosaic falls away.

The direct method suits small projects that are transportable. Another advantage of the direct method is that the resulting mosaic is progressively visible, allowing for any adjustments to tile color or placement.

The disadvantage of the direct method is that the artist must work directly at the chosen surface, which is often not practical for long periods of time, especially for large-scale projects. Also, it is difficult to control the evenness of the finished surface. This is of particular importance when creating a functional surface such as a floor or a table top.

A modern version of the direct method, sometimes called "double direct," is to work directly onto [[fiberglass mesh]]. The mosaic can then be constructed with the design visible on the surface and transported to its final location. Large work can be done in this way, with the mosaic being cut up for shipping and then reassembled for installation. It enables the artist to work in comfort in a studio rather than at the site of installation.

===Indirect method===
The indirect method of applying tesserae is often used for very large projects, projects with repetitive elements or for areas needing site specific shapes. Tesserae are applied face-down to a backing paper using a water-soluble adhesive. Once the mosaic is completed in the studio it is transferred in sections to the site and cemented, paper facing outwards. Once fixed the paper is dampened and removed. This method is most useful for extremely large projects as it gives the maker time to rework areas, allows the cementing of the tesserae to the backing panel to be carried out quickly in one operation and helps ensure that the front surfaces of the mosaic tiles and mosaic pieces are flat and in the same plane on the front, even when using tiles and pieces of differing thicknesses. Mosaic murals, benches and tabletops are some of the items usually made using the indirect method, as it results in a smoother and more even surface.<ref>{{cite web |url=http://mosaiclegs.com/ |title=Indirect Method Mosaic studio |year=1999 |access-date=26 October 2011}}</ref>
