Following your design, our Black Wax Resist leaves a black oxide line when fired. Fire cone 06 to cone 10. If fired higher, the black will fade then disappear altogether at Cone 10. Thinning is not recommended. Allow to dry for at least two hours before firing or applying a second coat. To darken the line from gray to black, use a clear overglaze. To use:Pour a small amount into a separate container, use as needed, then dispose of excess. DO NOT pour used wax back into the original container. Clean up with warm soapy water. To help with cleaning brushes, dip the brush in liquid soap then wipe off excess before using! Note:Aftosa Wax Resist has a shelf life of three years. Always keep the lid tight on the original container. The wax will FREEZE in cold climates and will not resist effectively. If frozen, it will get lumpy and separate.
