[papercreters] Ken's experiments: waterglass & AE

KEN CAINE  SAID:   Ingredients are water, paper, clay, lime, flour, borax. Have been playing
with various quantities of asphalt emulsion in it over the last 14 months
(in small mixes), and am now wondering if water glass might convey the same
-- or better -- water resistance and perhaps a stickier wet mix and harder
cured wall?
+++++++++++++++++

Ken---I think the cost of adding water glass inside the mix of sandy clay and paper  is too expensive, and not the best application for large wall surfaces.
 if you were making pottery maybe that would be fine.      AE is so sticky I don't think anything else can beat it.

I only had a small jar of it to paint on the paper lime mix.  I DO know that cobbers found that cob failed if covered with a coat of waterglass, as it didn't let moisture out of the clay.. clay naturally is hygroscopic..'water loving' so it will take  in a lot of moisture  and release it  easily...unless  moisture is trapped

 as an additive to coat clay particles AE is much cheaper if you need water resistance and can be added to clay and paper easily.    The basecoat of my metal drum-- a smooth enameled steel surface was coated with a  sawdust-clay-lime and AE mix that dried hard.  to get it to grip  the smooth metal I painted on a  thickish coat of AE and embedded strips of 'dress netting' while the AE was still wet ... it provided a  mesh  toothed surface to grip any plaster I could have added, and worked very well    I could have used  apple sacking, onion bags cut up,  or any wide open mesh  material, plastic or fabric.

Here is the specific web page he has on burlap/clay.paper.. also check out all his papercrete info...
a lot of great design ideas, and work he as done!

Also adding clay to coat the  burlap and taking it to failure with running a hose on it proves you can't leave it unprotected.   But why would you do that?
