Cathedrals are single color (some multi-colored mixes are available), with a very slight, irregular surface texture. Degree of light transmission is directly related to the density of the color. Clear or pale colors are highly transparent, while darker shades are close to being opaque. Some colors come in different textures. Glass texture can suggest depth, contrast, or movement. The most common textures are Hammered, Ripple, Granite, and Seedy. We also stock Red-Amber Streaky; Red-Clear Streaky; and Wisteria Granite.
