Its normally used in combination with a wide range of oxides and stain colorants to produce surfaces that are much more visually interesting

Brushing Medium, Laguna Speckled Stroke & Coat Underglazes Lithium carbonate reduces thermal expansionA glaze additive that can be added to any glaze or underglaze to improve brushing characteristics. Lengthens the drying time after the glaze is brushed on, and assists in glaze suspension. Can be used to convert a dipping or spraying glaze into a brushing glaze. We recommend adding 1. 5% of the dry glaze weight.
