I had tried twice to make sand casting follow the article of Kari
Brovold Hagen in the lovely book "Creative Ideas For Clay Artist, was
published first in CM.
As I don't intend to copy the article I will go forward and backward in
a way that I will not get a literature price for this letter.
It was a mistake to follow her great Idea of adding oil, to avoid
using too much water. On the other hand it was interesting to use
bentonite as an add. We know what bentonite and water do, We read that
Bentonite is being used to stop oil, from running. An emulsion. Nice
material. (Perhaps we can use it for Mayonnaise).
The first problem was What to do with the left over oily sand?
The second problem was What if I live in Texas or Shoval, where the
water dries fast, what for I need the oil in the mix?
Except making it all around dirty?
I suggest to start from the beginning. If you live New York or North
read her article and follow her directions. Actually this is not a
recipe but direction. as I said according to your climate.
If you live somewhere between Shoval L.A. San Diego or Johannesburg.
take sand add water and build a "negative" sand palace, in a wooden /
box cardboard full with sand.
The writer calls for a wooden box, similar to the kind you use
for preparing the plaster cast: Strong, but you can easily remove the
walls.
This is how I made it: Took a cardboard box wrapped it around with
plastic the kind you wrap around packages to reinforce the box. Inside
I put a plastic bag , to protect the paper box from the humidity of the
wet sand. Than added the sand and followed the explanations.
I failed twice. Yet It have learnt something.
I might repeat it in the summer.
I added a JPG to "Development of ideas" in my site. Perhaps If I would
a bigger studio and bigger patient. It would not have to be dumped.
