The word 'Tessera' is often used to describe one of the small shapes used to make a mosaic picture or pattern. Tessarae (the word for more than one tessera) used in ancient mosaics can be of stones of different colours, or cubes of fired clay or glass. Modern mosaics also make use of modern materials such as plastics or steel, etc.. The modern cathedral in Barcelona, Spain, is covered in a mosaic made of broken pottery and china.
Typically churches have stained-glass windows.
In my professional opinion, first off mosaics are popular because of the amount of detail involved in creating them, its a very meticulous type of work. Even the word mosaic means patient work of the muses. The sky is the limit when it comes to design and detail. Materials used can range from natural materials such as stones and marble to glass and other small objects.
They can really be used anywhere, in gardens, on paths, in churchs there are often mosaics on the roof or on windows.As mosaics can be made out of nearly anything, they can be used in lots of area's. Mosaics don't have to make a picture so they can simply cover a surface. People have even used mosaics to cover cars etc!
That is commonly why coloured paint is used.
It would depend on the lens. Higher quality lenses are coated with a substance to help eliminate distortion and light polution. If you look at the lenses glass and you see a multi-coloured reflection on the glass, then it is probably coated. Alcohol should not be used on these lenses. It would be better to use a camera lens specific cleaning cloth to clean them.
Glass was used as a lens protector. Now we use plastic.

Mosaics Were mainly Used For Decoration. They Originated In Rome Where People Would use Pieces Of Broken Tile Or Glass Too Make A Picture.Mosaics are pictures or patterns produced by arranging together small colored pieces of hard material, such as stone, tile, or glass.
An abaculus is a single tile of coloured glass or marble used in a mosaic pattern.
They were created by little pieces of glass Originally mosaics were made of pebbles of various natural colours. Later they were made of small pieces of stone, shells, ivory and other materials. Marble and limestone were also used. Later still, coloured and clear glass backed with metal foil was used. The Byzantines introduced gold leafs sandwiched between two flatter pieces of glass. The small pieces were called tessera (plural tesserae). There are two methods of making mosaics: The direct method is used especially for small portable three dimensional objects, such as vases. The tesserae are glued directly on the object's surface. The indirect method is used for large mosaics or repetitive patterns. The tesserae are applied face down of backing materials and then transferred to the floor or walls. There is also the double indirect method. This is a modern technique.
Five facts that I thought were interesting about Roman mosaics are that the design of how the tesserae will be laid out is scratched into a thin layer of mortar first, then the tesserae were placed on the mortar, following the pattern. Also, sometimes to make the mosaics very strong, they made a foundation out of broken stones and gravel, then put the mortar down and laid the tesserae out. Another fact I thought was interesting is that the way they designed mosaics is they had books called "pattern books" that had some designs to choose from. Sadly, none have survived. A fourth fact is that Roman mosaic artists almost never signed their work. Lastly, some of the first mosaics were made from colored rocks and pebbles instead of tesserae.
