Cone 06 oxidation (larger image) : Glo-Worm is a heavily pigmented, viscous Stroke & Coat®glaze that can be used for brush strokes or opaque coverage. One coat will create a translucent finish with subsequent coats adding opacity. We suggest two to three coats for full opacity and all over coverage. Will fire to a gloss finish without clear glaze. Cone 6 oxidation (smaller image) : Opaque. No color change.
