Sometimes a piece comes from the kiln and you feel you can make it better with more glaze and another firing. It is also a great time to experiment.
This bowl had pinholes and several craters. I sanded the rough edges with fine grit sandpaper. Then, I heated the bowl in my kiln ( glaze will stick to a warm surface). I poured Steven Hill Water Color Green into the bottom of the bowl, made marks with Amaco Saturation Metallic ( many dark “dots”) and reapplied Spectrum Cactus Ash glaze on the rim. I have found that commercial glazes are great for repairing flaws….they are stable and fire true to the cone intended.
I refined this bowl in my next cone 6 electric firing.
