To achieve good color results, thicker application is better, as this glaze is incredibly stable and does not run much. If firing in oxidation, a medium firing ramp with a 15-minute hold at the top temperature is sufficient to let any off-gassing pinholes seal over. 


The test tile on the left was fired to cone 6 in oxidation. The test tile on the right was fired to cone 10 in reduction.
