Cone 6 oxidation (larger image): Winter Wood is a matte white glaze that contains a variety of brown crystals that melt.
Cone 10 reduction (smaller image): Color changes to a translucent golden brown.
TIP: SW-106 Alabaster is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-106 Alabaster with a third coat of SW-155 Winter Wood.
