Lilac Liquid Underglaze is a soft orchid purple that is light and powdery at cone 05, becomes slightly deeper and fluxes into a soft glaze-like surface at cone 6, and begins to burn out at cone 10. Though the underglaze does become glaze-like, a clear gloss glaze can give Lilac an impeccably smooth surface and can help preserve some of the color at cone 10.
