Duncan Concepts Underglaze

Duncan Concepts Underglaze are underglaze colours designed primarily for decorating bisque. These colours are frit-based; therefore, when three coats are applied, they have a glossy sheen when fired. One, two, or three coats may be applied.

How to Use:

• Apply to shelf cone 04 bisque.
• Fire to shelf cone 06.
• For clear glaze application, brush-on or dip clear glaze over Concepts.
• Stilt and fire to shelf cone 06.
• Water cleanup.

Tips and Techniques

Opaque Coverage (solid without brushstrokes or light and dark areas)
1. Before decorating your piece, wipe down with damp sponge to remove any dust and to condition piece for decorating.
2. Apply three generous flowing coats with soft brush.
3. Always use the largest possible brush for the area to be decorated.
4. Apply each coat in the same direction.
5. Allow drying time between coats; a second or third coat should not be applied until the previous coat loses its sheen.
6. In most cases, Concepts do not need to be thinned. However, if the brush grabs or the paint ridges in application, then add a few drops of Thin ‘n Shade and mix with palette knife.

Translucent or Semi-translucent Coverage (brushstrokes show)
1. Apply one or two coats with a soft brush.
2. Primarily used for design work.
3. Colors may be blended one over another.
4. Colors may need to be thinned slightly.

Washes or Antique Finishes
1. Thin Concepts down to a milk-like consistency (about 4 parts water to 1 part color)
2. Apply to bisque with a soft brush.
3. Allow color to set (lose its sheen).
4. Wipe back with a damp sponge.
5. Rinse sponge as needed.
6. For best results, apply washes to textured pieces.

Sponging
1. Pick up Concepts on damp sponge, pounce color on ware.
2. Add additional color(s).
3. Work from light to dark.
4. The more coats, the darker the finish.
5. Sponge on three heavy coats to create an opaque, textured appearance.
