The Tuxton Artisan Collection brings reactive glazes to the table in earthy colors such as Agave, Mojave, Night Sky, Red Rock and Sagebrush. A reactive glaze flows a little differently on every piece, so no two plates, bowls or cups look quite alike, which gives each setting a handcrafted feel. Every piece is vitrified china, an ultra-durable, premium ceramic. Oven safe to 500°F, plus microwave, freezer and dishwasher safe, with no lead or cadmium. Tough enough for restaurant kitchens, with a lifetime edge chip limited warranty.
