Application Recommendations
The following application recommendations are based upon the original product development intentand use for the product. Information on alternative application methods is listed in the section UsageVariations and FAQ’s.
Underglazes can be used directly from the jar, but should be put out onto a tile to avoidpossible contamination of the remaining product in the jar. Make sure the consistency islike melted ice cream.
Apply to greenware, clay or bisque. Lightly dampening the ware with a moistenedsponge before painting allows better adhesion to the ware.
Dip a dampened, blotted brush into the color. Fully load the brush without draggingthe 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 usedwhen applying.
As you flow the color on, avoid ridges and runs. Brush these flaws out asyou apply the color.On an embossed piece do not allow excess color to build up. Brush the excess out of thecrevices as you apply the underglaze.
Apply the first coat. When the dark wet look has disappeared, apply the second coat at aright angle to the first. The third is then applied at a right angle to the second coat. Thiswill 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 vividnessof the product.
If applying to greenware or clay, fire first to cone 04 then apply atransparent glaze and fire to cone 06. If applying to bisque allow the Underglazes to dryand apply clear glaze and fire to cone 06/05
Opaque Underglazes are not true color out of the jar. Firing is required to mature theircolor.
Colors can be intermixed for custom colors.Underglazes can be fired to higher temperatures.
Usage Variations and FAQs
Q. What is meant by polishing an Underglaze?
A.While opaque underglazes can be applied to ware in many ways from brushing tosponging, there is an interesting technique that has survived the tests of time. One of themost striking looks can be achieved by polishing the surface of the color to produce a softsheen, and then leaving it unglazed. The finished surface resembles earthenware. Thistechnique 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 onlyused on decorative items and is not suitable for surfaces that come into contact with foodor drink. This technique creates a great background for spot glazing using a gloss ormatte glaze.A smooth surfaced piece works best for polishing Underglazes rather than an embossedpiece. Care must be taken to avoid removing the color from sharp angles and rims. It iseasy to scratch the ware accidentally with your fingernails, etc. Be careful when applyingthe color as any ridges or buildup of color will affect the end result. Use a silk sponge toapply the color to eliminate some of these problems and to give a different look. Somecolors polish better than others do.Apply three coats of underglaze with a brush, in the usual manner, to assure all overcoverage. Apply the colors very evenly and smoothly. Do not allow prolonged dryingtime 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 asmall area about the size of the palm of your hand. When the shiny wet look disappearsand the color will not stick to the pad, polish that area briskly. The pressure should belight 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 slightlyoverlapping the previous one, until the entire piece has been polished. Now buff theentire surface again, without wetting, until a high sheen has developed. If the color looksblotchy, this will disappear as the piece dries.If you wish to add a design using other opaque Underglazes, be careful not to mar thesurface. 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 thetransferring does not mar the surface.
