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.

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

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?
