Wax Resist is a water-based coating to prevent color from adhering when glaze is applied to bisque or greenware.
Wax Resist acts to repels glaze from the surface to which it is applied. As the kiln is fired the wax dissipates, leaving the surface beneath as it was prior to firing. It can be applied to unglazed greenware or bisque or it can be applied over previously applied, unfired color.
