Duncan E-Z Stroke underglazes are 29ml translucent ceramic underglazes for brushwork, antiquing, airbrushing, shading and detailed decoration. Their intense pigment and high-definition finish make them useful for soft watercolour effects, fine line work and layered colour on greenware or bisque.
E-Z Stroke colours can be applied to greenware, unfired glaze, soft-fired bisque or Cone 04 bisque. Use one coat for delicate translucent designs, or build depth with additional thin coats. Without clear glaze they fire to a matte finish; when coated with a food-safe clear glaze, they can be used for functional dinnerware as well as decorative ceramics.

E-Z Stroke colours are supplied at a light-cream consistency and can be thinned with water or Thin ’n Shade for wash, milk or light-cream effects. Use a glazed tile or palette for control, keep the brush well loaded and work smoothly to avoid dragging.
These translucent colours can be used over each other and over opaque underglazes, including sponged, stippled or solid backgrounds. The colour underneath will influence the final fired appearance.
For airbrushing, thin E-Z Stroke using two parts Thin ’n Shade to one part colour, or thin with water. For banding, thin to a milk or light-cream consistency and apply one smooth coat while the piece is centred on the banding wheel.
Thin the colour to suit the technique. Sponging works well for soft backgrounds or layered textures, stippling adds texture with quick pouncing strokes, and stencilling can be done with one thin coat through the stencil.
For antiquing, thin the colour to a wash consistency, apply to Cone 04 bisque, then wipe back with a damp sponge to remove colour from raised areas. Once dry, glaze with a clear or transparent glaze and fire to Cone 06.
E-Z Stroke colours can be applied over unfired non-moving glazes and fired to Cone 06. Keep application no heavier than light cream and use one or two light coats, as heavier application may cause texture or blistering.
Although designed for greenware, E-Z Stroke colours can also be used on bisque by lightly dampening the surface first. Colours perform across a wide firing range, but test firing is recommended, especially at higher temperatures.
E-Z Stroke colours can be blended together to create additional hues or used as colourants for slips and decorative products. Mixing ratios should generally not exceed 50% E-Z Stroke, and test firing is recommended when blending or tinting.
