Have you ever wondered where travertine comes from and how to turn into beautiful tiles that you can use for a kitchen, facade or floor?
Stone travertine mines
Travertine is a limestone formed in hot mineral springs all over the world.
Travertine rocks that are produced in these mines are different in terms of color, quality, depth and vein as a result of the geological changes associated with each mine.
Travertine is a limestone formed by the activity of hot springs. Generally, during the process of formation of travertine deposits, hot water passes through the classes of carbonate rocks, especially limestone, and because of its acidity, calcium carbonate dissolved in these rocks and dissolved in a carbonate and bicarbonate solution Transmit to Earth on their own. On the surface of the earth, due to the pressure drop, the reduction of carbon dioxide release and evaporation, the calcite crystals are formed and deposited in thin layers on each other.

On the surface of the earth, due to the pressure drop, the reduction of carbon dioxide release and evaporation, the calcite crystals are formed and deposited in thin layers on each other. The stability of the mentioned conditions and the continuity of the formation of calcite layers produce uniform layers of porous calcium carbonate (travertine), which vary in thickness from a few centimeters to several meters and usually with a mild slope on old stone layers The more they are.

How are travertine blocks extracted?
Travertine is extracted using one of four main methods:
1- Canal machines
2- Saw Wire
4. Cutting machine by water pressure
The channeling machines have a series of drill bits to create vertical and horizontal cavities that, after digging the hole, puts the cages in horizontal holes to remove the stone blocks from the mine wall and allow them to be removed. But during the winter, frozen water is used to separate the blocks from the mine wall.
The saw wire is usually used to cut the stone as much as the portable blocks to be transported to a factory or warehouse. The method is to drill access holes first, and diamonds wires rolled round the stone to Saws are attached. For these types of tasks, massive saws are used that move continuously or swirly.
Chainsaws are generally similar to those used for cutting trees, but a larger multi-purpose saw and diamond-cut blades for cutting rocks.
The car cutting by water pressure (water jet), this machine with the force of nature causes the cutting of rocks. This way, the device pours water at high pressure on the rocks, and this pressure above the water causes pressure on the rock and the stone is then cut.

The reasons for the use of travertine as a building stone:
1-4 acceptable resistance
2-4 Ideal cutting and polishing
3-4 ideal extraction conditions because they are often submerged in a horizontal slope in low points and achievable.
4-4. The absence of good tectonic structures on the travertine reserves due to its youngity (quaternary) after geologic orogenic phases have been geologically
Appearance Beauty 5-4
6-4 There is a porosity to adhere to cheap mortar 7-4 than other rocks.
5- The formation of colored travertine:
The limestone springs feed on the faults in the waters of the atmosphere and magma.
Influenced seawater waters are warmed up and accompanied by gases such as So2 + Co2, and elements such as Mg, Fe, etc., are brought to the upper levels of the earth. Calcium carbonate concentration has risen along the way, and at the same time, at the same time, The temperature, pressure and discharge of additional gases and ph changes cause the formation of travertine. Calcium bicarbonate is converted to calcium carbonate and precipitated. Changing the discharging regime, which is probably seasonal, causes changes in the amount of colorants such as Al, Mg, etc., and forms multiple layers with different colors.

The construction of stones is done in two ways: tile and slabs.
Tile Stone Dimensions:
The division of the thai and the slab is such that rocks with a width less than 80 cm are placed in the thai rock group.
Slab stone dimensions:
The rocks are about 80 cm wide in the group of slabs.
Cutting of slabs with devices called saws and multiviews and cutting of Tile rocks is generally done with the top of the device. In the stone mills of copper and slab, various plates are produced. A stone plant for cutting slabs into sheets of different thicknesses, cutting slabs into arbitrary geometric shapes and ordered dimensions (slabs and tiles), reinforcing sheets, improving the quality of stone, substring and polishing may have different parts.

Blocks of stone extracted in the form of slabs or blocks are shipped to gondola units. Unpackaged coupons may be due to the natural characteristics of the mine and the gaps and the type of extraction method. If the plant is only fed from mines that produce unpolluted cabs, the first machine is a slab-machine production line, if necessary, to sift the stone from a single-slam device (steel blades with 35 to 37 diamond teeth) Used. In some factories, instead of single slams, a variety of cutting machines or diamond and steel wire are used. With this blade, the stone block is cut from one or more sides to create smooth, dimensionally dimensional planes for saws. Then the block of stone from the part that is flattened is placed by the crane on the hammock and is pulled through special rails under the sawing.
Features such as the dimensions of the final product, the rock and its hardness are among the factors that are effective in choosing cutting methods and devices. Cutting and polishing machines are divided into two soft and hard types.
