Key Terms In The Stone Industry

In this article, we attempt to explain the Key Terms In The Stone Industry and give a succinct and clear definition.

This article includes the following:

Terms related to size

Stone Blocks

Large chunks of stone that are extracted from quarries are frequently shaped like cuboids or cubes and they might not have a regular geometric shape as a result of the method of extraction. These stones are called stone blocks and stone-cutting factories receive these stones for processing and cutting.

Slate Stone

Slate stones are natural stones (disharmonious stones), and they are formed by cutting larger stones into irregular shapes. These stones can be used to make road walls, tunnels, pathways as well as the outside walls of buildings and the flooring of walkways.

Slab Stone

Large chunk of cut stone, at least one meter long and one meter wide, with a thickness of 18 to 30 mm. Slab dimensions are usually 170* 280 cm.

Stone Tiles

Stone tiles are square–cut stones that are often utilized as floor stones.

Stacked Stone

Sacked stones typically have dimensions of 5 cm in width and 3 cm in thickness.

Stone Processing And Installation Terms

Book-matched Slab

Placing two slab stones (large stones that are one solid piece) so that the streaks and the way they look together create a perfect symmetry. It is sufficient to process cut pieces on the opposite side for this purpose.

Four-Matched Slab

Slab stones (large stones that are one solid piece) are arranged with two on top and two below, and their streaks and looks make a beautiful symmetry that is centered in the middle. It is sufficient to process cut pieces on the opposite side for this purpose.

Wavy And Waveless

When cutting sedimentary stones like travertine, the layer will be apparent and will take on a wavy appearance as a result of the variety of layers stacked on top of one another. Now, if the layers are cut in a way that is in line with the layers, these layers are hidden and the stone is waveless.

Twist Wave

The term twist wave refers to the wave shape that occurs in the stone when the waves in the stone do not extend on the same side and are twisted based on the sedimentation processes.

Shelf Angle

It is a series of methods for putting stone on a facade in which the stone is glued to the mortar on the back with unique metal pieces. With this method, the danger that the stone may fall from the facade due to weather conditions like cold, heat, or earthquakes will be greatly decreased.

Ashlar Stone

These stones have a thickness of about 4 cm and a non-flat surface that is made by special axes, and they form a stunning, natural state.

Bush Hammered Stone

Bush hammered, sometimes known as bush needle or sandblast, is a method of stone surface processing. In this process, a specialized diamond–tipped brush is installed on the polishing machine and circulates on the stone’s surface in both rotary and hammering ways, processing the stones surface uniformly (into a bulgy needle–shaped).

Stone Flaming

To flame a stone means putting a high–pressure flame on its surface to make friction on its surface.

Ridging

The process of using flame for turning a polished surface (stone) into a surface with high friction or creating a groove or sandblast on the surface.

Leathered

A type of stone finish in which the pores on the surface arent filled with resin. Also, the surface won`t be polished.

Terms Of Structure – Appearance Of Stone

Color Contrast

Play of color refers to the variation in color tonality within the general color of a sort of stone or plaque. Typically, this occurs in the form of the main color of the stone background.

Water Absorption

Water absorption is a measurement used to find out how much water a stone will absorb while submerged in water. This measurement is expressed as a percentage of the stone`s weight when dry. Water absorption is different in various stones and generally, sandstone and limestone absorb more water than granite stones, which absorb less water overall.

Abrasion Resistance

Abrasion resistance refers to the stone’s hardness and resistance to abrasion.

Bending Resistance

Bending resistance is the measure of a stone’s potential to bend without breaking.

Stone Efflorescence

Stone efflorescence is the term used to describe the deposition of salt and mineral salts caused by the evaporation of mortar water and the stone’s composition behind the stone.
