Fine Line Black Underglaze - Powder
For fine detail and texture. Thompson underglaze enamel coats metal surfaces, creating a clean glass substrate surface ready to receive additional enamel colors. The underglaze also eliminates oxidation. The base can give a nice contrast to light colors or metal foils. Lighter colors can also be applied to create different tones. Black would also allow for high contrast colors to show up better--such as an opaque white over the black. Apply with a brush or pen for fine lines.
Mix with Squeegee Oil
