Agar Ag06 (Solid, with Plasticizer)

Read the notes first!

Ingredients:

  • Water (10 mL)

  • Agar agar powder (3 g)

  • Glycerol (3 g)

Procedure:

  • Mix all the ingredients into a pan or pot

  • Heat up all the ingredients to 85-90 C on the stove

  • Mix thoroughly

  • Lower heat if bubbles are forming on the bottom of the pan

  • Take off heat after about 4 minutes of stirring or until the agar is fully dissolved (the solution is at least 85 C and thicker than when started)

  • Let dry for a few days on an ice tray or other suitable/mold surface

  • Done!

Properties:

  • Before drying: like a very grainy blob

  • After drying: grainy, sandy lump

Notes:

  • This was just for fun to see the minimum required water to make bioplastic

  • Do not try at home! This is not strong, and there was not enough water to thoroughly mix everything together, so the agar could not bond.
