Slate
Math is used in mosaics because you have to see how mamy tiles to use and also to measure how long it is
it would be 81 tiles
It depends on the units used for measuring the tiles. Obviously, the number of 18 inch x 18 inch tiles required will not be the same as 18 cm x 18 cm tiles. And if there were 18 yard x 18 yard tiles, you would need only 1.
It depends on the dimension used for measuring the tiles. Whether they are 12 in x 12 in or 12 cm x 12 cm will make a huge difference to the number of tiles required!
The answer is Slate. It is similar to Shale. It is still used but much less than 80 years ago. Slate is used in upscale roofing applications.
Slate is a common metamorphic rock used for tiles and roofs due to its durability, low water absorption, and ability to be split into thin sheets.
Marble is a metamorphic rock- statues, buildings, rolling pins Slate is also metamorphic and is used on roofs- tiles.
Basically to make them water proof and long-lasting.
Yes, plenty of people use slate tiles as a roof. However, they are designated to be used for the roof and not anything else.
Tiles is plural of "tile" which is a piece of baked clay used in covering roofs, walls, floors, game boards. I do not think that there is a synonym for "tile".
Slate is a fine-grained metamorphic rock that easily splits into thin layers, making it suitable for cutting into tiles. Gneiss, on the other hand, is a coarse-grained rock with a more irregular composition, which makes it harder to work with and less suitable for making tiles.
Paint,tiles and gloss
YES
they are used to make tiles or brick because of there durabiliy.
One common mineral used for making tiles is clay. Clay is abundant, easily moldable when wet, and hardens when fired in a kiln, making it an ideal material for producing tiles. Other minerals like feldspar and quartz are also used in the production of certain types of tiles.
The are used for making tiles
None. Roman buildings were made of either wood, stone or brick. Tiles were only used for the roofs, as they could easily be replaced if damaged.
