Perhaps the backsplashes from this Carlsbad, California, company are so fine-looking because, of the four original partners in Oceanside Glasstile, two were professors of fine arts from Cal State at Fullerton, one a master glass blower. In 1992, no one was using glass, much less recycled glass, as a commercial medium for decorative tile: The quartet built their first equipment from spare parts. Demand for the gemlike and iridescent tiles they developed was swift in arriving; soon OG was reproducing an arcane formula for cobalt mosaic tile for the restoration of the Roman Pool at Hearst Castle. Today, clients worldwide marvel at the bounty of OG’s exquisitely calibrated palette of graceful hues: Minerali, textured and iridescent metallics in earth and water colors; opalescent Haiku; tumbled matte Rituals (a proprietary soft-satin finish); mosaic Tessera (descended from the Hearst job and still the “rock star”? of the line); and Terrain, just introduced, which looks down for inspiration, so to speak, to pebbles, pond ripples, ground cover and leaf skeletons, and ridged and sheared stone.
