SC-015 Tuxedo - Deep Black Ceramic Underglaze & Glaze, Mayco Stroke & Coat®

SC-015 Tuxedo delivers one of the truest, deepest blacks available in a brush-on glaze. Even a single thin coat offers a clean black tone without gray or brown undertones. With two to three coats, it becomes a fully opaque, jet-black gloss finish that absorbs light and creates dramatic depth. Formulated with a high pigment load, Tuxedo flows smoothly and evenly without streaking or breaking. It performs consistently from Cone 06 up to Cone 6, maintaining its deep black tone even at higher temperatures—unlike many black glazes that shift toward brown or gray. Because it does not run or bleed, it's ideal for fine brushwork, graphic line work, and layered designs. It offers sharp, clean edges and strong contrast when placed next to bright or light colors—making it a reliable go-to black for both functional and decorative ceramics.

Stroke & Coat® SC-015 Tuxedo is a highly pigmented, viscous gloss glaze that can be used for both detailed design and opaque coverage. It is designed to stay in place without blending when layered, making it perfect for intricate artwork. The colors are intermixable, allowing for custom shades. Artists can thin the glaze with water to achieve a watercolor or wash effect. Since the liquid color closely matches the fired result, it’s easy to visualize the final appearance, drastic changes are unlikely. Brush-able, water soluble, and non-toxic.  

Stroke & Coat® works on wet or leatherhard clay and can be fired to cone 04, maintaining vibrant color with time savings. It’s ideal for classrooms, studios, and fine art use. It can be applied to earthenware or terracotta clay and bisque. One coat results in a translucent finish, while 2-3 coats build up to full opacity. Allow drying between coats. Stroke & Coat® naturally fires to a gloss finish, but clear glazes such as NTCLR Clear One Dipping or S-2101 Crystal Clear Brushing Glaze may be added for extra gloss or evenness. It is AP Certified Non-Toxic and dinnerware safe when used properly.
