Grape Jelly is a highly pigmented, dense Stroke & Coat glaze ideal for brush strokes or complete coverage. One coat yields a see-through appearance, with additional coats increasing opacity. For full coverage and maximum opacity, we recommend two or three coats. When fired, this glaze will achieve a glossy finish without the need for a clear glaze. At Cone 6, it becomes semi-transparent and transitions to a deep blue hue.
