Sandblasting:

Sandblasting, also known as abrasive blasting, is a process of propelling fine particles or abrasive media at high speeds to etch, clean, or texture a surface. It involves using compressed air or a blasting machine to direct the abrasive material, such as sand, silica, glass beads, or crushed walnut shells, onto the surface being treated. The abrasive particles impact the surface, removing unwanted coatings, rust, or debris and creating a textured or patterned effect. Sandblasting is commonly used on various materials, including metal, concrete, glass, and wood. It is often employed for decorative purposes, such as etching designs or logos on glass or creating textured surfaces on concrete for aesthetic appeal.
