Very bright lemon yellow. The cleanest yellow stable at high temperatures.
Specific Gravity: 4.0-4.75
Excellent in all types of glazes and bodies for firing at temperatures up to 1300C. Should preferably be fired in an oxidising atmosphere. Where slightly reducing conditions are encountered, zircon-praseodymium yellows have considerably greater stability than tin-vanadium yellows.
Suitable for blending with all other types of ceramic colors. Widely used in blends with zircon-vanadium blues to produce very clean, bright and stable shades of green, the specific gravities of the two being similar enough to avoid the risks of color separation.
Note: This description is taken from information provided by Blythe Matthey and may or may not apply to stains of this family from other companies.
Best results are obtained with leadless glazes having low alkali contents.
Either tin oxide or zircon may be used as an opacifier. The use of zircon helps to prevent solution of the stain by the glaze.
Underglaze Color: The exceptionally clean shades and excellent stabilities of zircon-praseodymium yellows make them ideal for use under all types of glazes for firing to temperatures up to 1300C.
Suitable for all types of bodies and slips for firing at temperatures up to 1300C. Displays no tendency to strike or flash. May be fired under reducing conditions.
