Aqua Liquid Underglaze is a soft blue green that is very pastel at cone 05, becomes a much deeper blue green while fluxing into a soft glaze-like surface at cone 6, and ends up losing a lot of color at cone 10. Though the underglaze does become glaze-like, a clear gloss glaze can give Aqua an impeccably smooth surface with good color at cone 05 and cone 6, but can burn out some of the color at cone 10.
