Make your own plaster cast for Cast Drawing

You can make a plaster cast for little money because plaster is a very cheap material and plaster casts can easily be made.

There are two different techniques which I recommend for making your own plaster cast. Alginate is a powder which thickens when mixed with water and can capture fine details.

Plaster bandages are a very cheap alternative but since they are not flexible as the Alginate you can’t make moulds with deep undercuts and which go all around.

So if you would like to make a hand cast you should use Alginate and if you would like to make a face cast plaster bandages are the better alternative.

Alginate

There are several kits available for making castings of body parts but I recommend the Alja-Safe Lifecasting Starter Kit. Watch the video below on how to use it. As you can see it is very easy and can also be fun for you and your family. Imagine you could make a casting of your child’s hand and later make a Cast Drawing of it.

You can also cast other body parts as an ear like in the video below.

Or you can make a cast of your hand resting on a flat surface.

Plaster bandages

It is also possible to make a plaster cast with even less money. With plaster bandages you can make a mold for cheap. Watch the following video on how to make a plaster cast of your face. You’ll need the help of another person with this techique. Also be careful with your hair – cover your hair with toilet paper and use plenty of vaseline for your eye brows and eye lashes.

Always rub the wet plaster bandage thoroughly to get rid of the pattern texture from the bandages and get a smooth finish.

When pouring the plaster of Paris into the face mould knock the side of the mould several times to let air bubbles come to the surface. If they do not burst on the surface try to burst them by blowing on them with your mouth.
Then pour the plaster into the mould while taking care not to get air bubbles into the plaster again.

You can put a paper clip half way into the wet plaster and fixate it so when the plaster has cured you can hang the cast on the wall.
Let the plaster cure for several hours before you try to carefully release it from the mould.
I recommend to let the still wet plaster dry for at least a week or so on a warm place.
