Amaco LUG 21 Medium Blue Liquid Underglaze, Pint

Medium Blue Liquid Underglaze is an electric blue color that is soft and bright at cone 05, becomes more intense and fluxes into a soft glaze-like surface at cone 6, and maintains a strong blue tone with a soft sheen all the way to cone 10. Though the underglaze does become glaze-like, a clear gloss glaze can give Medium Blue an impeccably smooth finish with good color at cone 05 and cone 6, but tends to cause some transparency in the surface at cone 10.
