Subject: Re: [Puptcrit] Make your own detail loop tols.


Hi Robert.
I'm using plastalina.

The loop tools would work on a lot of modellin compounds, as long as they 
are not too hard for the tool.


Just in case some of you don't know, Plastalina is an oil-base clay that 
does not dry out.
In theory.
(I read that it is usually made of real clay, a mineral oil, some 
waxes(beeswax is more expensive than parrafin, so there often is a mix) and 
some color.
My experiments modifying the clays seem to confirm at least the clay 
content.

I am currently working with inferior-grade stuff, because I was on a tight 
budget for when I made the 7 Commedia masks I just finished. I could get the 
pro stuff because o the huge quantity I needed to work on all 7 masks at 
once. What I have right now is, believe it or not: Giotto Pongo, a very 
cheap kids modelling clay. I of course tested it before buying it bulk. It 
accepts details very well and smooths well when you know how to do it. Once 
re-conditionned(a little mineral oil or vaseline added when clay is heated), 
it works the same way as Chavant Lebeautouche, a brand I was using before 
(much more expensive).

I dream of re-equipping myself with Roma Plastalina, or Chavant 
NSP(non-suplhur formula).

The kids stuff still works very well when the weather is not too cold, but 
it gets crumbly fast (a week)when put on plaster forms (plaster absorbs the 
oil), so I need to re-condition it from time to time (using a double boiler 
at low heat, I add a few drops of mineral oil to the clay and mix well until 
it is all liquid, then let cool.

For the puppets I'm making right now, there is no plaster involved at the 
sculpting stage, so no prob.

I am looking for a permanent way to seal plaster of paris.
Nothing I've tried resists the clay so far, the clay pulls any sealer right 
off the plaster, and I'm left with raw plaster again. So the oil keeps 
getting abosrbed.
I even tried heating some mineral oil and rubbing it into the plaster, 
hoping to saturate it.
No success.

My next attempt should be to use real old-style floor wax, as a pro sculptor 
reccomended.
Unfortunately, I cannot locate any. People no longer wax their floors, it 
seems.
