New tableware. Copper reds and greens

I have been focusing on controlling the kiln atmoshere to affect the colour of the glaze. With a heavy reduction I can create a deep blood red, but by alowing oxygen to be sucked into the kiln unevenly, early in the reduction it becomes flashed across the surface.
With a later reduction, I can create a azure blue, and a pale vermillion also using copper.

Having an old kiln means that I can control the amount of oygen going into the kiln by adding or taking the insulation that is around the kiln. But a new kiln would need to have air holes built in.
