I chose plaster of paris because I have never used it before and I'm familiar with cement and masonry. Here are the experiments I will be running to determine its properties. Obviously each experiment will be more detailed and thorough, however this is just the basics.
Experiment I: Casting a part using a mold
a.) find or make a mold, mix and pour plaster, let cure, remove from mold
b.) Materials: plaster, water, mold, mixing utensil
Experiment II: Series of adding foreign objects and materials
a.) mix and pour plaster, add objects while curing or over mold before pouring
b.) Materials: plaster, water, mold, different objects
Experiment III: Series of finishing techniques
a.) mix and pour plaster into simple mold for repetition, sanding, wet sanding, painting
b.) Materials: plaster, water, mold, sandpaper, spray paint
MATERIALS: Plaster of paris
Water
Rubber gloves
Mixing bucket
Mixing utensil
Acrylic paint
Acrylic primer
Styrene for molds?
Different objects for impregnating
