Cone 6 oxidation: Muddy Waters is a matte brown glaze with crystals that melt into a glossy blue. Heavier crystal application will produce more color variation.
Cone 10 reduction (second image): Glossy blue becomes more prominent. Increased movement.
TIP: SW-174 Leather is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-174 Leather with a third coat of SW-179 Muddy Waters.
