Techniques and processes- Alginate and Plaster

Following on from my sketches of hands and objects they can hold i started to experiment with 3d modeling and casting.
I mixed up a large pot of alginate and placed my hand into it and waited about 4 minutes for it to set.
When it was set i then carefully wiggled my hand free trying not to damage the mould too much in the process but it is quite flexible so it made the process a little easier.
From that point i mixed up a tub of plaster and poured it into the negative to create a positive.

The process is a one off only as you have to break the mould to get the plaster out. As you can see from the images below it worked very well and the alginate picked up little detail like the folds  by the knuckles and even some skin pores and texture.


i painted the second cast using oil paints to create a realistic hand
