THe DRUM WAS SLICK ENAMELED STEEL. I USED A blue ladies' DRESS NETTING stuck to a wet (non toxic) ASPHALT EMULSION PAINTED ON TO MAKE A SCRATCHY "TOOTHY" SURFACE, THEN I COVERED WITH A CLAY & AE [RUB-R-SLATE] MIX, left bumpy for more grip, THEN THE LIME-paper PLASTER. And TADELEKT IS A PURE LIME PLASTER, not sure how they make a sink of it, as it needs to be thin layers to cure like any lime- a 1-2" thick lime plaster will stay soft for years or decades if sheltered from air. Since the lime is turning back to limestone ALSO, the waterglass was an aide, not a full solution I think. soaking a thin wafer of the paper -lime Does crumble if kept under water. Charmaine I question man-made global warming and have NO financial or emotional interest in the status quo. real science tells the truth-everything is cyclical On Feb 6, 2007, at 12:44 PM, Ron Becker wrote: This comes as a surprise as I read in a few places that waterglass is not water proof and disolves in water. It's dangerous to get most of my info from reading. The drum was a cool idea and again I'd have bet the plaster wouldn't have stayed. What was the surface to the drum like? Ron Those who question global warming have a financial or emotional interest in the status quo.
