I tweaked the iron content, feldspar, and my firing cycle. The increased iron and g200 fluxed the glazes which will allow me to fire a cooler. I was having to hit ^11 which made my reds almost burn out in hot spots. Now I can barely drop ^10 and I can get the melt I was looking for. As with any discovery there is a cost. I lost about $500 in pots from running in this load.....Oh well. Such is ceramics!
