2014-02-14 03:02:23

This is a craft recipe to make extra strong plaster of Paris for casting. Objects that you make using this plaster of Paris recipe will dry very hard and smooth. This plaster dries so hard that you can sand your objects with a fine grain sandpaper to give them an extra smooth finish. You can use extra strong plaster of Paris with any plastic or rubber molds that are suitable for plaster casting. Casting molds are available at any craft or hobby store and are not expensive. You can also household items as molds such as cardboard boxes, cans, muffin tins, ice cube tray, etc. Simply apply a good coat of Vaseline petroleum jelly to the entire surface of the mold you are using so the plaster will not stick. If you are using a cardboard box as a mold, you can rip the cardboard off the plaster when it is dry.

from rain damage.
