Grandpa Pencil
learns how to make
Plastic from Milk


Make your own easy plastic at home from milk curd (casein) to build your own ornaments.
After a few experiments to get your volumes right and determine your drying times,
you will be able to make a range of personalised plastic objects.
Make buttons, beads, brooches, models, dolls or even a pencil box that is exclusively yours.

 

Ingredients

  • 300 ml Milk

  • 1 tablespoon vinegar
 

You will need

Straining cloth, spoon, saucepan, a bowl that will hold the milk and a suitable mould.

 

Directions

  • Warm the milk in a saucepan without boiling it
  • Add a tablespoon of vinegar and stir in.
  • A thick, white material will form in the milk. This is the cassein that will make your plastic.
  • Strain the milk through a straining cloth, into the bowl, and squeeze the straining cloth until it holds only the sludgy stuff.

  • Form the cassein into your chosen mould and allow to dry and set.
  • The moulds might be interesting chocolate moulds of jelly moulds or just about anything else that takes your fancy.
  • If you are making brooches or drops push your pins, clips or rings in while the mix is still wet. Then you can paint or decorate it with glitter.
