This transparent glaze adds a little manganese and iron, just enough to give color, but still maintain transparency to highlight the decorative crack-network in the engobe below. However this glaze is not as brilliant and transparent as it could be. As apparent in the surface reflections, it has somewhat of an "orange peel" texture on the glass surface. This is due to a combination of factors (e.g. not enough melt fluidity, gassing of the manganese during melting, cooling the kiln too quickly). If the colorants were transplanted into a more fluid-melt transparent, this glaze could be improved. Photo courtesy of J. Decker.
