Sand-blasting
Technology used for surface modification of materials. Sand-blasting creates a motif, logo, or inscription on the item by the blasting of soft sand, which results in removal of a thin layer of the blasted item and the creation of a relief. Sand-blasting works with a special template, through which the blasted sand affects only the one place, where the motif will be. Sand-blasting is used for glass and metal items (glasses, bottles, memorial tables, etc.)
