Subject: [Puptcrit] TECH: speeding Latex with vinegar: results2


I'm persistant.
I was able to control the flow of vinegar between layers of latex , finally. 
I just poured some vinegar inside the latex covered mold, moved it around, 
made sure to get into all details, and finished spreading it with a very 
soft watercolor brush. Then I poured the excess out, into a bowl to re-use 
for future coats.
Then I proceed with pouring the latex in and rotocasting, letting it drip 
all its excess.
Since there is less vinegar involved between latex layers, the setting takes 
more time, about 10 minutes per layer.

I did 5 layers of the latex in reccord time. There are still problems, the 
main one being that the latex does not grab the vinegar-treated mold as 
well, therefore shrinkage and some separation does happen on the sides, and 
at the 4th layer, the borders kept lifting and falling into the mold when I 
was rotocasting by hand. Very annoying.

For the last latex puppet on this project, I'm going back to the non-vinegar 
method, because there is no shrinkage nor separation, and I can still 
speed-dry every layer at about 15 minutes, using a regular fan. For closed 
one-part molds, I use a hairdryer, at cold setting, with nozzle inserted 
inside. I sometimes use medium heat, when I need to, if I notice a thicker 
lump.


I'm glad to have tried it all. I learned a lot that can be used for other 
specific purposes for puppetmaking!
