New Mexico Clay - Smooth Red (Cone 5/6) Smooth Red is a vibrant, smooth red clay that showcases a striking red color in oxidation at cone 5-6 and turns a rich chocolate hue in reduction. Known for its high plasticity, this clay is ideal for throwing, though it should be dried slowly and evenly if working on larger pieces to prevent warping. During firing, adding a small amount of fresh kiln-wash or fine sand under the piece can help accommodate shrinkage. Be mindful that Smooth Red 6 has a strong colorant, so it may eventually stain your shoelaces red! Perfect for eye-catching ceramics, this clay combines aesthetic appeal with practical versatility.
