Oceanside Glasstile combines up to 85 percent recycled glass with raw sand to generate many of its glass tile offerings. The freeze- and thaw- resistant products come in more than 40 colors and finishes, including mosaics, textured designs, and smooth field tiles. The company's manufacturing process reclaims more than 800 tons of discarded glass each year, it says. Oceanside Glasstile, 760.929.4000; www.glasstile.com.
