A collection of porcelain tile designed to evoke the look of natural volcanic stone contrasting with glazed porcelain tile. In this collection, earth-toned matte natural basalt is designed to be juxtaposed with Raku, a colorful porcelain tile. A slight iridescence on the Raku tiles provides an additional layer of refinement and intrigue. The effect is an atmosphere of contrasting elements that, when combined, equals harmony. This collection also has 3-dimensional tiles that can be used on their own or paired with other materials from the collection.
