What is etching?

Exclusive Granite - FAQs
Etching happens when acid in some form comes in contact with a polished marble or limestone surface. This causes a chemical reaction, which removes the polish, or roughens the surface of honed marble or limestone. Green marbles, such as the "jades" from China are resistant to etching, and granite is impervious to any common household acids. Some green stones, such as the "jades" from Taiwan, are not truly marble, but a different material called serpentine.

Etching is one of the oldest art printing forms. The artist uses tools similar to dental tools to scratch and burnish a vanish covered zinc plate. This is followed by bathing the plate in nitric acid, and burning the metal away with the acid. This basic etching process is repeated several times, depending on the image. Once the plate is complete, printing can start. The paper is dampened in order to be flexible enough to contour to the highs and lows of the metal etching plate.

Q.How does an impregnator reduce the staining prospects of natural stone?

Stone Source
The solid part of silicone impregnators are microscopic balls of silicone that attach themselves to the crevices inside the stone. These balls of silicone are negatively charged, which means they repel each other so that they cannot combine in one big ball of silicone. Once they are attached to the stone, these balls become a permanent part of the stone, and give out a magnetic charge, which creates an invisible "umbrella" between the balls.
