Spectrum Cone 06 - 6 Underglazes

(501 - 570): A full palette of rich, vibrant colors that are opaque with three coats, semi-opaque with two coats and semi-transparent with one coat. They are compatible for use under most clear glazes. We suggest that you try them with one of Spectrum's clear glazes (700 Clear cone 06/04, 250 Satin Clear cone 06/04, 1100 Transparent cone 4/6, 1120 Satin Clear cone 4/6 or 1200 Transparent cone 9/10).

Unlike many other brands of underglaze Spectrum uses a frit base rather than a slip (clay) base for the 500 series underglazes. The advantages to the user are that these 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 matte velvet like surface. However, when used without a clear glaze cover they are not considered dinnerware safe because the rough surface can be difficult to clean and can encourage bacteria growth.

The color chart below shows the unglazed color in the upper left half of the tile and the color when covered by a clear gloss glaze in the lower right half of the tile. The color chart samples were fired at cone 05. The 500 series underglazes generally have good temperature stability up to cone 6 and for many colors to cone 10. When fired hotter than cone 04 you may get small color variations from those shown on our charts, so please test them for your application. Our underglazes can be intermixed to create your own colors. However, Spectrum recommends not mixing 561, 562, 563 with any of the other colors. These colors are based on cadmium encapsulated stains that do not mix well with other ceramic stain colors. All of the underglaze colors are lead-free, dinnerware safe and A/P non-toxic.
