PLASTER OF PARIS

ca: GUIX DE PARÍS

es: YESO DE PARÍS

Plaster of Paris: Is an industrially made powder used for many different purposes from mending broken bones to making molds. It is very easy to work with, just pour water into a bucket and tip the plaster of Paris into it until rises above the water level. Mix, stir and smooth out all the lumps by hand, using a large metal beater for cooking or a paddle paint mixer which can be attached to an electric drill. In about 3 minutes it will start to thicken and when it acquires a heavy texture, pour it over or into the piece you have prepared to make a mold from. Read more about: Mold
