There are various means of etching, among them are laser and acid etching.
We use sand carving. Sand carving, also known as sand blasting, works very well on glass. Wine glasses, window panes, vases, and glass awards can all be beautifully and elegantly transformed into a memorable gift, or a piece for yourself.
Ceramics are also great media for sandblast etching. Coffee cups, mugs, and tiles can all be etched by sand carving.
Most metals can also be etched with sandblasting. Unlike glass and ceramic carving, however, on metals, we do surface etching, and do not significantly penetrate the substrate.
