Velvet Underglazes

AMACO VELVET UNDERGLAZES offer two finish possibilities. When left unglazed, they have the appearance of soft velour or velvet. Under a matte glaze (like Duncan SN351) they assume a soft, satiny finish. The colors intensify under a gloss glaze (like Duncan IN1001). All the Velvets are very rich colors and can be used for all-over coverage similar to opaque underglazes. They fire true to color as applied from the jar and can be intermixed to product hundreds of colors. Fire to cone 05, but can be taken up to cone 6-10 with some changes.

Gallons are available only in the following colors by Special Order:
V308 Yellow - V326 Medium Blue - V360 White - V361 Jet Black - V387 Bright Red

--- V390 Bright Orange - mold and black coloring issues ---

Reds, oranges, and some bright yellows were only a dream in minds of potters for any temperature
over ^05, without the use of lead and stability up cones 10-11. This is because the glazes were made
from leaded frits and raw cadmium-selenium sulfides. They would essentially burn away if slow fired
or fired over cone 05.

Today due to the invention of cadmium-selenium sulfide encapsulated pigments in the 1970s and
their continuous improvements since then, we now have safe reds, oranges, and yellows. The same
materials are used to make the pigments themselves (cadmium-selenium sulfides) but now they are
encapsulated in a protective high-temperature ceramic shell. This is what protects the pigment from
burning out.

These pigments can sit in the jar for a year or better before they are opened for use. A very small
amount of the pigment shells may have cracks in them and allow some small solubility if the sulfides
go out into the glaze. This is what you smell. It smells like rotten eggs because the smell is the sulfide
from the pigment which is the same as in bad eggs. A few drops of bleach will get rid of the smell.
When the cadmium stains break down the sulfur it releases, it accelerates the molding process,
turning the glaze black.

** The discoloration of the raw underglaze will not affect the fired color **

 

Zinc-Free Clear

Zinc-Free Clear is a glossy transparent glaze that produces attractive high fire glossy effects at the mid-range temperatures. Zinc can cause some pigments in slips and underglazes to shift in color, this clear glaze was formulated to prevent those color shifts. -- Safety Warning -- Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
