This was my first real fine art ceramic piece that crosses the line between utilitarian and purely decorative. This is one of a series of “black iron” ceramic pieces. The glaze is a cone 10 glaze over white stoneware. I created this glaze on a whim one day trying to achieve the blackest of blacks with a slight metallic feel. The trick however was to fire it to cone 6. This gave the glaze its black iron appearance. The glaze become molten but not hot enough to glassify and run. The glaze itself would be enormously expensive to produce in today’s market. It has a very high metal content. The highest percentage being Cobalt Oxide. So not only is the cobalt EXPENSIVE it is toxic as are a couple other chemical in that glaze. So working with it required a bit of caution. At cone 6 this came out much more amazing than I had expected. Firing the glaze to cone 10 produces a very shiny black glaze which my studio mate Ben Owen was even pleased with. I think I gave him the recipe to work out for his own super black glaze. I hope he still uses a descendant of that glaze.
