Iran Marble Travertine Onyx Limestone:

Iran stone

Marble is formed from limestone by heat and pressure in the earth's crust. These forces cause the limestone to change in texture and makeup. This process is called re crystallization. Fossilized materials in the limestone, along with its original carbonate minerals, recrystallise and form large, coarse grains of calcite. Impurities present in the limestone during re crystallization affect the mineral composition of the marble that forms. The minerals that result from impurities give marble wide variety of colours. The purest calcite marble is white.
Iran marble containing hematite has a reddish colour. Marble that has limonite is yellow, and marble with serpentine is green.

Travertine stone is soft and delicate to look at. It breathes spaciousness. It's relaxed and soothing. The feeling is peaceful, tranquil, serene.

Marble is a relatively soft stone. On a measurement of hardness (MOHS), marble is approximately a three out of ten. Marble is made of calcium, just like your teeth. If you eat something to hard you will break your tooth. If you eat a lot of sugar you will get a cavity. Stone reacts the same way. If an improper chemical is applied to the surface, corrosion will begin to form cavities in the stone.
Listed below is the famous Measurement of Hardness (MOH) Scale for stone. This is a guide developed in the 1800's which helps evaluate the strengths and weaknesses of the stone being used. For example, softer stones would require the use of a less active chemical and a more frequent dust mopping program.

Measurement Of Hardness Scale:

10 Diamond
9 Corundum
8 Topaz
7 Quartz (Granite)
6 Feldspar (Granite)
5 Apatite
4 Fluorite
3 Calcite (Most Marbles)
2 Gypsum
1 Talc

The objective of the MOH Scale is to measure stones resistance to hardness. When sediment and grit are harder than the surface, they will scratch and harm the stone. For example, a piece of hard plastic is about a 2.0. It will not scratch #3 Calcite (Marble). However, a piece of sand that measures a 6, will scratch #3 Calcite but will not scratch #7 Quartz which is Granite. The harder the stone, the more resistant it is to abrasion. Exterior sediment that is tracked in to buildings approximately measures from 3.0 to 7.0.
