Which Type of Paint should I use?
Read the following general review of glazes and underglazes to determine which type of paint to use on your ceramic project.
Note: 1oz glaze covers approximately 30 square
inches.
One 6" x 6" tile uses less than 1oz underglaze and just a bit more
than one ounce glaze. One 8" x 8" tile uses almost 2oz glaze.
Underglazes
As the name implies this is a non-flowing (during firing), usually non-shiny paint that goes under another glaze.
If you are painting on greenware ~ If you
prefer to detail paint on greenware you should use an underglaze. CoverCoats
opaque underglazes, EZ Strokes Translucent underglazes or Western UG
underglazes are ideal for this application.
CoverCoats and UGs are
applied to greenware and absorbed into the clay. Since they are clay-based
paints they literally become part of the clay piece during firing. CoverCoats
require three coats for complete opaque coverage and can be used to color large
areas. So, you could paint your teapot with 3 coats of black CC118, then paint
flowers and leaves over the black (3 coats on flowers and leaves) and the black
will not show through. CoverCoats can be tinted using EZ Strokes or other
CoverCoats, to create unique custom colors. Or paint 3 coats of a darker color,
then sgraffito (gently scratch through the color to reveal the clay color
underneath) a design onto your piece. When piece is to your liking, bisque fire
to cone 04.
Note: Some CoverCoats can
be painted on bisque. However, it should be noted that after CoverCoats
application the piece must be fired to cone 04 to 'set' the paint and make it
adhere to the bisque. Then is should be glazed and fired to cone 06.
EZ Strokes are translucent and very reminiscent of painting with watercolors. They can be used alone on greenware or bisque, and can be used over CoverCoats for shading and detail work. EZ Strokes can also be used with Concepts Underglaze for Bisque. Remember that E-Z Strokes are like working with watercolors and are very translucent. Brush strokes are highly visible. E-Z Strokes can also be used to 'antique' your ceramic piece. Just wash the watered-down color onto the detailed areas of your piece (greenware or bisque), then sponge off the high sections and smooth areas, leaving the color just in the crevices. And lastly, EZ Strokes can be painted on over your unfired glaze (which has been applied to bisque) for a Majolica look.
If you are
painting on bisque ~ If you prefer to detail paint on bisque you
should use Concepts Underglazes for Bisque or Stroke n Coats Wonderglaze for
Bisque. The first coat is translucent, the second is semi-opaque, the third
gives full opaque coverage. If you apply three coats you don't have to put a
clear glaze over this product as it will be shiny. However, if any of your
bisque shows through you will need clear glaze to seal the item. Also,
underglazes for bisque are not considered to be safe for dinnerware until they
are sealed with clear glaze. You can use either Concepts Clear Dipping Glaze -
CN2000D or Pure Brilliance brush on glaze - PB2639 over Concepts.
Both
EZ Strokes and Concepts are great for Majolica design. Simply cover your bisque
with three smooth, even coats of white satin glaze, drying between each coat.
Paint your design onto the white glaze with either EZ Strokes, Concepts or
Stroke n Coat, then fire to cone 06.
