STONES RIFINING TYPES

Thanks to its know-how, Persit Star provides different refine types of the stones, sold as follows:

This type of surface refining is a mechanical process that, through the usage of abrasive material with a grain that reduces its particles volume progressively, weaken and lighten the colour surface. This chemical process also gives opacity to the material and makes the surface smooth and even.

The treatment preserves the natural and esthetic characteristics of the material itself.

This refining-type is obtained by brushing the surface with a plastic or metal brush.

This strong action removes the soft particles of the stone and wears-out the surface providing an antique aspect to the surface.

It has to do with uneven, rough, and with variable relief surfaces that are obtained from the mechanical fracture of the slabs. This mechanical process allows to see the natural surface underneath by taking advantage of the mechanical property of the stone to split towards a specific direction.

This cut-type is recommended for an open-air usage due to its skid-proof feature.

This process is executed after having sequentially calibrated and smoothed the surface in order to remove all the surface imperfections. Then, once the surface is made smooth, is ready to be polished. This type of cut is the most common; it sharpens the chromatic qualities and makes the surfaces perfectly shiny.

The marbles polishing is a chemical process obtained by the usage of abrasive and acidic tools. Particularly, the chemical reaction that occurs with the usage of these tools, and the chemical properties of the material itself, results in a superficial coat that makes the surface to shine.

It is possible to wash pre-cut pieces or the settled pieces with prudence. Some chemical agents lead to results that influence the aspect of the stone rather than the roughness of it. These agents are acids that are able to remove the oily spots or the rust from the material.

However, there are other kinds of acids that oxide the surface and are used to change the colour of the material.

Is a technique that provides a skid-proof surface that is suitable for open-air spaces or wet areas.

This refine-type is obtained by spraying sand, ceramic pearls or other abrasive elements with compressed air on the surface of the stone. This process tends to bleach the stone.

This refining-type is greatly appreciated; it reproduces a specific esthetic effect.

The aberrations of the edges and the surfaces refer to the action over time, to the wear-out due to the usage, as well as to the illusion of a hand-made work rather than and hypothetic nature of the material. The antiques refine is obtained by the usage of machinery that utilize lightly abrasive water mixture that uses up the pieces due to the rolling process, the impact, and other mechanical movements. The residuals themselves of the pieces left contribute to the artificial overuse.
