Cone 6: Weathered Blue is designed to produce a blue to white variegation depending on application. One coat will produce a sky blue matte finish with little white variegation. Subsequent coats build a white variegation, muting the sky blue. Cone 10: Off-white variation darkens. TIP: Thinned coats produce a sky blue satin finish. Thick applications will increase white variegation. Brush stroke application is visible in finished results. We recommend applying coats on bisque in different directions (crosshatch). Although finish appear sopaque, surface decoration can be easily seen through glaze.
