  1. It could be that too much lead has evaporated from these ^6 glazes if you fire too slowly. I found a ceramics journal from 1904 which quantifies the percentage of the lead in a glaze, fired in a sagger, which vaporized per hour. Journal of the Society of Chemical Industry, Volume 23 - Society of Chemical Industry (Great Britain) 1904 http://books.google.com/books?id=lkLOAAAAMAAJ&pg=PA470&dq=kiln+firing+%22lead+glaze%22+loss+per+hour&hl=en&sa=X&ei=qhTnUpKpAYPvoASxlIGoCw&ved=0CDsQ6AEwAA#v=onepage&q=kiln%20firing%20%22lead%20glaze%22%20loss%20per%20hour&
  2. Metallic Rain, which I have not tried, is similar in chemistry to Spectrum Metallic Mirror and Amaco Palladium. Amaco says their leaded Palladium is not dinnerware safe, but Spectrum says leaded Metallic Mirror is food-safe based on the glassy non-leeching finish of the glaze "Contains some heavy metals and/or cadmium compounds but passes test for lead and cadmium release.". You need a small amount of lead to create this type of look. But they don't use enough lead to make these glazes reliable. I think you'd be far happier with a standard ^05 lead-manganese glaze like these s
  3. I think a lot of commercial ware has to be made using Metal Vapor Deposition in a vacuum like Canadian artist Trudy Golley outlines in her article. Thanks so much for sharing this. It seems obvious in retrospect. It's how mylar is aluminized for tinsel and emergency blankets. Hardly a surprise that Golley learned how to do this in the ceramic village of Jingdezhen. I'm beginning to find that village annoying - what haven't they perfected there? Am I going to have to move there to satisfy my vexation end envy? Titanium and Chrome are certainly less expensive and more durable th
  4. The pine cone is a collection of bisqued leaves assembled into a core of non-shrinking ceramic paste, then rebisqued and glazed. Manganese glaze covers the core and inner part of the leaves.
  5. Return of the Duck in Orange Sauce. An assemblage of a variety of ^6 glazed clays and porcelain pieces assembled with low-fire glaze and low-fire glaze mixed with orange COE 96 glass frit. The New Zealand Frost Orange wedge is filled with orange COE 96 glass frit, with an orange mason stain on the rind covered by a thin layer of low-fire clear.
  6. I tried to capture the look of photos of various ducks landing on water. This particular duck had to land in a pool with a wingspan no wider than our kiln, so he had to be captured at the moment he began tucking his wings back into a retracted position. I made it with Laguna WC-370 Amador clay which has so much grog it's almost like using paper-clay. The companion piece, Return of the Duck in Orange Sauce, is an assemblage of a variety of ^6 glazed clays and porcelain pieces assembled with low-fire glaze and low-fire glaze mixed with orange COE 96 glass frit.
  7. You can do much the same thing with Copper Carbonate or oxide with Ferro Frit 3269.
