The most distinctive characteristic of onyx is its ability to glow when backlit. GREY BUBBLE ONYX can be used in interior wall claddings, decorative panels, niches, and fireplace surrounds; as an accent surface in hotel and residential projects; in selected areas of bathrooms and wet spaces; and, under controlled conditions, for countertops or console surfaces. For every project, usage intensity and performance expectations should always be evaluated together with technical considerations. As with all natural stones, maintenance and cleaning habits are decisive in onyx applications. Applying surface protection treatments, using neutral pH cleaners, and avoiding chemical-based products help preserve the long-term appearance of GREY BUBBLE ONYX.
