Our solar kiln build is progressing nicely. We got most of the roof (except the ridge cap) installed at the weekend, and insulation in the south wall.

Already, even on a cloudy day in February in #vermont (peaked at 24,000 lx), we still saw a temperature differential of +14°F vs outside.

Just need a sunny day to see how it’ll really perform! Hoping to get more done this weekend.

Yesterday was #KilnChristmas, so I'll show you guys some pots later. (Have to wait until the light gets brighter in our condo for the best photos.) #Pottery #Ceramics
