How formed travertine stone?

Travertine is a type of sedimentary rock formed by the precipitation of calcium carbonate from water, usually in hot springs. It is characterized by its porous texture and distinct veining patterns.

Travertine formation beings when underground water, often containing high concentrations of dissolved calcium carbonate, cones in contact with air or emerges at the surface. As the water is exposed to the air, carbon dioxide is released, causing the calcium carbonate to precipitate out of the solution.

Over time, these precipitates accumulate and build up into layers, forming the characteristic pitted texture of travertine. The trapped gases also create voids within the stone, giving it its porous nature.

Travertine has been used as a building material for centuries due to its durability, aesthetic appeal, and the ease with which it can be shaped and carved. It is commonly used in flooring, countertops, and decorative elements such as columns and sculptures.

Which items make its color?

The color of travertine stone is determined by various factors, including impurities and mineral content present during its formation.

The primary mineral in travertine is calcium carbonate, which is white or light colored.

However, impurities such as iron oxides, clay, or organic matter can give travertine stone its various colors, ranging from white and cream to beige, brown, and even reddish tones.

Additionally, other geological conditions and environmental factors during its formation can influence its coloration. For example, travertine formed in hot springs with high levels of dissolved minerals may have a more vibrant and varied color palette. 

It is important to note that the color of travertine can also be enhanced or manipulated through various treatments and finishes applied to the stone surface. These treatments include honing, filling, polishing, or acid washing, which can alter the appearance and color intensity of the travertine.

What factors make red travertine?

The presence of certain impurities and primary minerals determines the color of red travertine. The main factor that contributes to the red coloring in the travertine is the presence of iron oxide, also known as hematite. When iron oxide is present in the stone, it imparts a reddish hue to the travertine.

In addition to iron oxide, other impurities and minerals may also play a role in creating red travertine. These can include organic matter, clay minerals, or other forms of iron such as goethite. The specific combination and concentration of these impurities and minerals, along with other environmental factors during travertine formation, contribute to the varying shades of red in the stone.  

It is worth nothing that red travertine is relatively less common compared to the other colors of travertine, and its availability can be limited. As a result, red travertine is often considered more unique and prized for its distinct appearance.

Which items make more light color travertine?

The color of light travertine can be influenced by a variety of factors, including the presence of certain minerals and impurities. Some of the items that can be contributed to a light colored travertine including: calcium carbonate: travertine is primarily composed of the calcium carbonate, which gives the stone its characteristic light color, iron and other minerals.

How to pick the blocks at the quarry? 

you should know because of the color quarry and direct light of the sun your eyes probably make mistakes as every where become reddish in your eyes and cant see the errors of the blocks so check the blocks many times. 

Whats more you should be careful about mud line around the block 

Also the most important point is crack line that maybe be so thin it not be around the stone.
