Lost foam with packaging peanuts.


The current system:
Packaging peanuts are glued together with hot glue and pour spouts are made out of pink insulation.I have used both drywall mud and plaster and found that plaster is much better for holding the shape.

After the foam is coated with plaster it is buried in play sand and the metal is pour over burning out the foam.

Cleaning the plaster off is a pain. Currently I do it by soaking the piece and working out the plaster with a fine metal tool and a wire brush. I was thinking a pressure washer or sand blaster might work well.
The hot glue sometimes obstructs the profusion of the metal. In this piece one of the rear legs is not getting the metal.

  1. I'd of never thought to do that. by golly packing peanuts!

  2. what is the purpose of burying the plaster in sand? could i just dig a hole in my yard and stick it down in it? :)
    (I casted once in college sculpture but do not remember the processes at all- i really want to try this though)

  3. I bury it is sand so I can use less plaster the nice thing about sand compared to dirt is that it has no moisture to heat up and steam.


i'm not here right now but leave a message and i will get back to you as soon as possible.
