Light Yellow Liquid Underglaze is a light daffodil yellow that is pale and powdery at cone 05, becomes a deep lemony yellow and fluxes into a soft glaze-like surface at cone 6, and lightens slightly at cone 10 with some slight pinholing. Though the underglaze does become glaze-like, a clear gloss glaze can give Light Yellow an impeccably smooth surface with good color.

Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
