2nd copper red firing

Second firing of copper reds in gas kiln. Got new shelves and soaps for the lower level of the kiln since this gets so hot. Raised the first shelf up to full soap height. Fired again trying to slow down the firing but was unable to get the kiln into reduction by 1650 F so ended up with all copper greens. Cooled too fast and some pots were broken. Top again no cones melted in 8/9/10 pack bottom shelf ^10 melted.
