So for this large batch of pieces I used a dark, red stoneware clay called “Brooklyn Red”. This clay is heavy, groggy and due to the iron oxide content will stain anything it touches (before firing of course). It’s actually the kind of clay used to make red bricks and in is incredibly durable once fired. It is great for hand building pieces as it has minimal shrinkage during drying and and attached parts really hold together.
I also love this clay as it gives you a rich, dark ground to work off of- perfect for the metallic glazes I wanted to use for these pieces-I used 2 different combinations of Potter Choice Glazes from Amaco. In group one I applied 2 thick layers of Saturation Gold to the piece. Then I coated that in a blotchy layer of Temmoku (a dark, translucent brown/black glaze) and Saturation Metallic. After those layers dried I applied a little more saturation gold to the edges and rims of each piece for a little pop of gold.During firing the glazes melded beautifully. In the areas with a thinner layer of Saturation Gold the glaze developed a dark bronze coloration that flashes iridescent blue when viewed at certain angles. The splotches of Temmoku and Saturation Metallic gave silvery, pewter-like touches and in areas where the Saturation Gold pooled and dripped you can see these patches of rich gold with little coppery flecks.
In the second group (which turned out to be my fav) I applied a couple thin layers of Saturation Metallic glaze over the dried clay body then a splotchy layer of Temmoku with thick blotches of Saturation Gold.This combination of glazes developed a rich and complex black metallic finish with patches of pewter and ancient bronze. On these little dishes I made with torn edges (the clay had started to dry out and had become unmanageable) the finish almost makes them look like shards of a meteorite-It’s always nice when an experiment turns out even better results than you were expecting!
