Cobalt Crystal Black - Duncan Cover Coats Glaze 59ml

59ml squeeze tube

Cover Coat underglazes provide solid coverage over even the darkest colours, and are perfect for brushwork or airbrushing. They give a matte effect by themselves but give the truest colour with a transparent top coat.

Painting with Cover-Coats is similar to painting with acrylic paints and is a great fired alternative for a decorative painter. Colours are opaque and generally one colour covers the one beneath it. They must be fired to ensure maturation and stability. 

Cover-Coats fire to an opaque, porous matte finish.

we found they work great fired to 1000°c - 1040°c
