After seeing the water curtain spray booths of Bill Campbell and Paul Lorber, plus photos of the ones by Tom Turner and Avi Harriman I figured "What the hey, huh!?" I always planned to outfit the "booth" Ginny did her spray demo in at the Electric Reduction Symposium with water guts. Phil has been a tremendous help this summer with the fabrication (and the trials and tribulations of doing something tweeky for the old man) and put a great system together.

| I guess I keep torturing this poor pot hoping to learn something. |
Hopefully these glaze catchers machined from scrap insulation will work well after a surface coating. |
Alumina Hydrate makes a nice slurry @ 1:1 with water and casts quickly on this 90% porous material. |
Zircopax casts much slower and mud cracks to death on drying. It's probably of no value as an impenetrable layer. |
More and more people have been asking to take photos on the yard. This weekend's happy couple had a great day, never mind that it was 98 in the shade.

7-14-10 I refired and held in oxidation for 4 hours. The pieces came out about as I expected although I'd prefer the deep red to be a little less deep. I do like the red speckled background though. Decisions.....decisions!!!!!! Do I re-oxidize more? Do I scrub them down with a little abrasive cleaner and elbow grease? Do I just plain leave well enough alone and move on?

7-8-10 The latest collaborative effort - a new set of shelves (oak and cherry with walnut & mahogany inlays) was just installed at the bottom of the staircase. I moved all (well most of) the "non - PDH" pieces that were up in the studio to them and am rearranging things to make way for the next wave of work.

| A selection of new work by Steve Boehme. He wrote "The under-glaze painting was protected from the glaze by the slab built frame. I carved a small channel around the frames so the glaze could flow around the images." The middle one - Green Fish - is my favorite. | Kat, always "The Poser", started to work in the office this summer. She is hot stuff with just about everything she touches. | ||

6-28-10 The reduction firing went as planned but I came home to an "E3" due to a power interruption. The load only saw ~ 5 minutes in oxidation at peak temperature.

Oxidizing with the plugs out. |
Firing Curve | After 5 minutes of oxidation at 810°C. |
6-27-10 I fired another group of pieces trying to attain the same level of reduction in a single firing and a less dramatic re-oxidation to try and retain more red. The previous firing saw about 8 1/2 hours of re-oxidation over the course of the 4 firings.
6-23-10 This piece is glazed with a 413 base with 1/2% cobalt carbonate and 2% copper carbonate. After the initial ^11 oxidation crystalline firing it has seen 3 reduction cycles and 4 oxidation cycles to 1500F with various hold times.
