New Mexico Clay - Cashmere (Cone 5/6) Cashmere Porcelain Clay is a smooth, cream-white clay designed to offer the throwability of B-Mix clays with a refined finish. While not a true porcelain like Pecos, Cashmere incorporates a white ball clay, resulting in a workable and versatile material. The new and improved cleaner feldspar enhances its brightness and whiteness, giving it a vibrant, clean look. This clay shares similarities with Cashmere Slip, providing a consistent texture and color while being ideal for a range of ceramic projects.
