Classic
& Timeless
Underglazes
were the first product line Mayco produced in 1954 and continues to be a staple
for many ceramic artists. Mayco Fundamentals Underglazes are highly versatile
and may be used for complete coverage or in design, applied to clay or bisque
and have a broad firing range from Cone 04 to Cone 10.
Whether used by a student making his first pinch-pot or by a fine
artist making gallery quality work, Mayco Underglazes will stand the tests
of time and demand in performance.
General
Use
Apply to green-ware or shelf cone 04 bisque. For best results,
apply color in a flowing motion, keeping brush adequately loaded with
glaze. Allow first coat to dry. Apply second coat at a right angle to
first coat. If desired, apply third coat at right angle to second coat. If
applied to green-ware, fire to shelf cone 04. If desired, apply clear
glaze and re-fire to shelf cone 06/05. If applied to bisque, clear glaze
can be applied directly to the unfired Underglaze and then fired to shelf cone
06/05.
Application
Recommendations
The following application recommendations are based upon the
original product development intent and use for the product.
·
Underglazes can be used directly from the jar but should be put
out onto a tile to avoid possible contamination of the remaining product
in the jar. Make sure the consistency is like melted ice cream.
·
Apply to greenware, clay or bisque. Lightly dampening the ware
with a moistened sponge before painting allows better adhesion to the
ware.
·
Dip a dampened, blotted brush into the color. Fully load the brush
without dragging the brush on the side of the tile. Apply the color in a
flowing motion; if it starts to drag, reload the brush. The clay will
absorb the moisture from the color, so care has to be used when applying.
·
As you flow the color on, avoid ridges and runs. Brush these flaws
out as you apply the color. On an embossed piece do not allow excess
color to build up. Brush the excess out of the crevices as you apply the
underglaze.
·
Apply the first coat. When the dark wet look has disappeared,
apply the second coat at a right angle to the first. The third is then
applied at a right angle to the second coat. This will assure better
coverage.
·
Underglazes can also be applied by sponging and spattering.
·
Generally a clear glaze finish is applied after to bring out the
true color and vividness of the product.
·
If applying to greenware or clay, fire first to cone 04 then apply
a transparent glaze and fire to cone 06. If applying to bisque allow the
Underglazes to dry and apply clear glaze and fire to cone 06/05
·
Opaque Underglazes are not true color out of the jar. Firing is
required to mature their color.
·
Colors can be intermixed for custom colors. Underglazes can
be fired to higher temperatures.

Q. What is meant by "polishing" an Underglaze?
A. While opaque underglazes can be applied to ware in many ways
from brushing to sponging, there is an interesting technique that has
survived the tests of time. One of the most striking looks can be achieved
by polishing the surface of the color to produce a soft sheen, and then
leaving it unglazed. The finished surface resembles earthenware.
This technique cannot be obtained by any other method and is unique to
opaque underglazes. The beautiful surface is achieved by buffing the
opaque underglaze while it is still damp. While the surface is somewhat
sealed, it will not be waterproof. This technique is only used on
decorative items and is not suitable for surfaces that come into contact with
food or drink. This technique creates a great background for spot glazing
using a gloss or matte glaze. A smooth surfaced piece works best for
polishing Underglazes rather than an embossed piece. Care must be taken to
avoid removing the color from sharp angles and rims. It is easy to scratch
the ware accidentally with your fingernails, etc. Be careful when
applying the color as any ridges or buildup of color will affect the end
result. Use a silk sponge to apply the color to eliminate some of these
problems and to give a different look. Some colors polish better than
others do. Apply three coats of underglaze with a brush, in the usual
manner, to assure all over coverage. Apply the colors very evenly and
smoothly. Do not allow prolonged drying time between the coats. Thin the
same color with water in equal proportions, mix well. Using a ball of soft
facial tissue or soft T-shirt material, apply the thinned mixture to
a small area about the size of the palm of your hand. When the shiny wet
look disappears and the color will not stick to the pad, polish that area
briskly. The pressure should be light and the movement fast. It is the
friction from the polishing that develops the sheen. Continue to apply the
diluted color mixture to a small area at a time, each one slightly overlapping
the previous one, until the entire piece has been polished. Now buff
the entire surface again, without wetting, until a high sheen has
developed. If the color looks blotchy, this will disappear as the piece
dries. If you wish to add a design using other opaque Underglazes, be
careful not to mar the surface. Use a soft cloth to hold the piece to
protect it from body oils and moisture. Wait until the piece has
thoroughly dried before tracing the design so the pressure of the transferring
does not mar the surface.
