SOLID SURFACE UPDATE Avonite Avonite was the second solid-surfacing product to come on the market, and is available in 45 styles, including 16 Granites, 13 Crystelles, 10 Formstones, and 6 Gemstones. Avonite is the only company that offers a choice of material composition. The company's Advantage series is manufactured from a mineral-filled (aluminum trihydrate) polyester base and has a Class-1 flame-spread rating. The Decor series is made from an unfilled polyester and has one of the deepest translucent looks on the market. This series is not as hard as the other products, and should not be used in "high wear" areas. Its Class-3 flame-spread rating may restrict its use in some commercial applications. Formstone,
