From Spectrum about Spectrum Underglaze:   
We offer a full palette of rich, vibrant underglaze colours that are opaque with 3 coats, semi-opaque with 2 coats and semi-transparent with 1 coat.  They are compatible for use under most clear glazes.  Unlike many other brands of underglaze, we use a frit base rather than a slip (clay) base for our underglazes.  The advantages to the user are that our underglazes can be applied on greenware or  bisque and they can be used with or without a clear glaze covering.  When used without a clear glaze cover they have a matt velvet like surface.  Our color charts show the unglazed colour in the upper left half of the tile and the colour when covered by a clear gloss glaze in the lower right half of the time.  The color chart samples were fired at cone 05.  When fired hotter you may get some variation in the colour.

AMACO Velvets are fabulous! They are so versatile and consistent. I could talk for days about the things I like about them, but instead, I'd like to share a fun idea I heard from Steve Howell at the Las Vegas NCECA conference: Start with a plaster surface. Next, tear up strips of newspaper and lay them down on the plaster in an interesting pattern, leaving parts of the plaster still showing. Then pick a Velvet and brush it on over the plaster surface. Then pull up a strip or two of newspaper. Pick another color of velvet and brush on over the newly revealed plaster. Pull up a few more strips of paper, etc. Then, when all the strips of newspaper are removed, pour liquid slip over your velvet design. Let it sit until it drys. Then, carefully transfer the slip to a hump mold placed on your wheel. Use some more of the slip to throw a foot. let it dry on the hump mold until it is dry enough to support its own weight. Then turn it over to dry. At this point, you will ! be able to view the design of your velvets from the torn newspaper. It's really cool. Steve showed slides of some of his pieces that he had created in this way. Remember in using this technique, that the first color you apply will be the frontmost color and the last will be the backmost color. Good Luck and have fun!
