Alkaline green glaze test
Here's an non barium, alkaline copper green test tile from my last firing, on Phoenix, a light stoneware from Highwater, . I designed it for cone 8- 10 but this was in a section that had cone 12 starting. The expansion is pretty high which accounts for the crazing, which probably was increased due to it overfiring.
I love the color, so I'll be interested in seeing what this will do at Cone 10. I was hoping that it would be more of a turquoise; but when you have to add enough silica for cone 10, it tends to shift the alkaline to a more acidic environment which makes you lose that brighter, turquoise color. I need to try lowering the expansion without losing the color - more testing to come!
It was an eventful morning with the sound of fire trucks coming down the road, only to realize they were at a neighbors house across the road. Unfortunately, it looks like the house was gutted. No one was home. If they were, the house might have been saved. The information I got from a friend is that it looks like it was a chimney fire; and it was only when the roof seemed to be on fire that another neighbor noticed it and called 911. I can't imagine having to deal with the devastation of coming home to fine your home and everything gone - too sad to even contemplate.
Our long driveway is covered with a new layer of snow, so we're going to stay put for a few days until these snows stop, which should be Thursday or Friday. In the mean time I'm pretending it's spring and ordering seeds, starting some seeds of cold tolerant vegetables, cooking and enjoying the Olympic events.
Dinner is already prepped, other than making a salad later, so I think I'll get another loaf of cinnamon raisin bread started. Somewhere in this huge pile of papers is the bread machine manual and recipes!
