2017-10-25 - Wednesday - Scummy

While the glazed pots sat on the shelf overnight the soluble salts surfaced in the shino glaze in what we call "scumming up". The salt crystals trap the carbon during the reduction firing making the shinos work, so scumming up is a good thing.

We finished loading the kiln and started candling it for tomorrow's firing. When I left it was up to 573 F with a long way to go.
