Stillwater Porcelain's 5 1/2" x 5 1/2" botanical trivets are spectacular gifts of nature. Our high-quality porcelain products are fired to over 2,100°F, making our trivets heat-tolerant and durable. The colored glazes are fired into the work; the matte finish is washable. Special bas relief designs are chosen for the trivets, which require a balanced, raised surface. Underneath are four cork disks for support.
