Underglaze is usually applied to greenware, sometimes to bisque.  It is similar to colored clay.  It is often used for painting detailed designs, as it doesn't move during firing.  It can be fired over a wide temperature range.  Often, particularly in functional ware, it is covered with a clear or translucent glaze.

Amaco Underglaze

LUG   

Amaco Liquid Underglaze Decorating Colors are concentrated, opaque colors recommended for covering large areas quickly, easily and smoothly.  Results are equally effective when the colors are used for detailed painting, sgraffito decoration, water color effects, free brush painting, wax resists and mishima decoration.   Colors may be brushed on greenware which is to be bisque fired before applying a covering glaze, or on mature Cone 04 bisque, then covering glaze applied and fired to maturity temperature of the clear glaze.  Also use for coloring slip or clay.
Amaco Semi-moist Underglaze

Set 108. 109, 110, 111  

 

AMACO® Semi-Moist and Tube Underglaze Decorating Colors are suitable for many types of ceramic painting.  They are especially good for water color effects and painting of fine detail.

Decorating colors are concentrated, intense and opaque.  Additional shades and tints can be made by intermixing.  Colors may be brushed on either bisque or greenware.  A brush dipped in water lifts the color for decorating.  Further thinning of the water soluble colors prepares them for transparent water color effects by brushing.  Tube Underglaze Colors are the correct consistency for silk screen printing.  Because the colors are approximately the same tone before and after firing, the effectiveness of color combinations and blending can be observed as painting progresses. Colors dry quickly and may be handled without damage.  All colors in the Semi-Moist Underglaze Series are AP NON-TOXIC.
Amaco Velvet Underglaze

V  

Velvets are a very versatile, semi-translucent underglaze which offers two finish possibilities.  When left unglazed they have the appearance of velvet.  Or, when glazed with a clear gloss glaze, they have a soft, satin matt finish.  They are rich colors and can be used for all over coverage similar to an opaque underglaze.  Colors may be mixed together to create unique colors.  Use on greenware, then bisque prior to applying a clear glaze.  Or use on bisque with a covering glaze applied prior to firing.  Velvets tolerate a wide firing range, and can be used on most temperatures and clay bodies.  Some colors may fade at high temperatures (cone 7 and up).  When used without a glaze cover, Velvets should not be used on food or drink containers.   Non-toxic. 
Amaco Majolica Gloss  SALE
GDC    20% off
Majolica Gloss Decorating Colors for bisque or Majolica.  Maybe applied using Majolica technique, or may be used in a one step underglaze method:  Apply GDC colors directly over Cone 04 bisque to create a design, then apply clear glaze and fire.  There is no need to fire the GDC before applying the clear glaze.  However, clear glaze should be applied by dipping or by sponging.  One coat of GDC will create translucent designs, or apply 2-3 coats for a more solid color.

Duncan EZ Strokes Translucent

EZ 

EZ Strokes have become popular for their versatility.  Their translucent quality makes them suitable for use with a number of decorating techniques including airbrushing, antiquing and brushwork.   One stroke is all you need for most design work.  One or two additional strokes may be added for depth and shading while the color is still wet.  (Do not apply additional coats after the color has dried, or the heavy buildup may cause popping off, bleed, or bubbling).  E-Z strokes may be applied over most underglazes, including Cover-Coats and other E-Z stroke colors, allowing the base color to show through.  They may also be used to tint clay slip, most glazes, and other E-Z stroke colors.  May be used on greenware or bisqueware.  For best results fire to cone 06 after application, then glaze fire.  Glaze fire from cone 06-1.  Some colors will go to cone 10 oxidation.

Concepts are often used for painting onto already fired tiles and dinnerware, then re-firing.  Even though it is an underglaze, many have reported good success using them in this manner.

Duncan Cover-Coats

CC 
For solid-color, 3-coat coverage on greenware.  Some colors may also be applied to bisque (check label.)  Cover-Coats fire to an opaque, porous matte finish.  A clear glaze finish is used to seal the porous surface and to brighten the underglaze colors.   Colors may be tinted with E-Z Strokes or other Cover-Coats.   Colors shine with polishing technique which is done by completing application, mixing a further quantity of the color half and half with water, and applying to small sections of the piece at a time.  Just as the wet look disappears, polish briskly with a soft cloth.  Overlap each area as you go until finished to a satin sheen.  After firing this surface will be water resistant but not waterproof. 
Amaco Sun Strokes Brilliant Underglazes

SS  

Vivid reds, oranges, yellow and green!  Six intense special underglazes specifi­cally formulated for Cone 06-05 in oxidation and raku firings—with or without a clear glaze. 
Sun Strokes Underglazes have a gloss finish even when fired without the clear glaze.  Therefore if they are applied on the bottom of the piece, they must be stilted when fired or they will stick to the kiln shelf.  Clear glaze smoothes out and brightens the colors.   Now are non-toxic!
